Summit Health Avis 

I was diagnosed with Polymyalgia Rheumatica (PMR) in May this year, and the only treatment my GP offered me was long-term steroids. I decided to take some time to research the condition for myself and look into whether there were other ways I could support my health alongside managing my PMR.

That’s when I came across Dorian and Nicola at Summit Health. I had an initial call with them, and so much of what they explained made sense to me. What particularly appealed to me was that, as functional medicine nutritionists, they don’t simply focus on nutrition. They look at the whole picture — diet, lifestyle, stress, sleep, movement and other factors that can influence how you feel.

Over the three-month programme, I made significant changes to both my diet and lifestyle. The combination of educational videos, weekly one-to-one calls and weekly group calls gave me the knowledge, support and accountability I needed to make those changes.

For me, the results have been transformational. The pain and stiffness I had been experiencing gradually receded, and I began to recognise some of the triggers that seemed to make my symptoms worse. Understanding those triggers has given me the ability to make changes and take a much more proactive approach to managing my condition.

I have kept a diary from day one, which has been incredibly useful in seeing just how far I have come. Looking back at where I started compared with where I am now has been really encouraging.

I finish the three-month programme with my blood inflammation markers in the normal range, and my pain and stiffness much more under control. More importantly, I leave with a much greater understanding of my body, a better understanding of what supports my wellbeing, and a significant improvement in my mental resilience.

I know that PMR is a condition I may have to manage for some time, and I hope that one day it will go into remission. But I now feel that I have the knowledge, tools and confidence to move forward and live as normal a life as possible with it.

A huge thank you to both Dorian and Nicola for their expertise, encouragement and continued support throughout my journey. I’m incredibly grateful that I found Summit Health when I did.

The Summit Health Reversal Formula has been a great experience for me. Both Dorian and Nicola are extremely well informed and brilliant at their job. I had severe symptoms of Autoimmunity before the Program but with their help, my health has improved sigificantly. I wouldn't hesitate in recommending them to others.

I found summit health through Instagram after months of searching for the right programme and course for me after being diagnosed with an ultra rare autoimmune condition. They’ve been excellent at helping, guiding and encouraging me through this difficult time. As well as teaching in a way that is scientific yet understandable. I would highly recommend, they’ve been an instrumental support in my recovery journey.
Thank you Team summit health!

I was looking on Instagram and saw Dorian explaining his story about his personal recovery turnaround - his dedicated work with helping people with long term health issues - I had an immediate intuition to go deeper and find out more about his work.

I was careful because obviously there are so many ‘so called’ practitioners selling themselves and maybe their cures or supplements etc - but Dorian is not this - he has incredibly wide knowledgable and truly supportive in wanting to help his clients to grow their health again and take their lives back after often much pain and frustration from mainstream medical practitioners who don’t have the ability or time to support and explain the deeper issues that lead to possibly true recoveries.

Working with Dorian and Nicola together has taught me so much more about what has happened to me (and from me) and how to follow a new way to change the root causes of my many years of thyroid issues, compromised immune system with histamine inflammation and consequences from living in foreign countries and some overwhelming diseases which had left my life restricted and painful for many years.

The program that Dorian and Nicole have created and are helping me navigate is at first seemingly obvious but truly needs determination to make step by step root changes to feel the absolute blessing of have more well days than I ever thought would be mine again. It seems easy to say but it is hard work to confront habits and beliefs.

I am just coming to the ending of the initial 3 months of the Summit Health program but the heart felt support and amazing information from Dorian and Nicola has been and is superb. Its not easy to deeply explain in a review how important it is to have such sincere and informed support from Dorian and Nicola and the Summit Health course they give.

Anybody who has been unwell for years and gone through the agonies and fears - those walls of helplessness alone - knows much of what heals is honest knowledge and kind support. I am gaining more foundations to continue working on those very fundamental healing roots knowing I am not alone and have profound information and support from Dorian and Nicola. My fears are becoming my new road maps... with Guides!

When I first came across Dorian and Summit Health, I had been living with Hashimoto’s Disease for over 10 years. I’d gone from being fit, active, and able to take part in triathlons — even completing the Ironman in 2015 — to feeling completely lost in my own body. By the time I met Dorian, my health was poor, the symptoms were overwhelming, and I couldn’t see a way back to feeling like myself again.

Over the 12‑week programme, everything changed.

Dorian helped me understand why my body wasn’t responding to the prescribed medication and uncovered the true underlying issues affecting my health. For the first time in a decade, I finally understood what was happening — and more importantly, what I could do about it.

The knowledge, support, and genuine care I received from both Dorian and Nicola have been exceptional. This isn’t just a programme; it’s a journey of discovery that empowers you to rebuild your health, your confidence, and your life. I now feel like a new person — and I know this is only the beginning.

I would recommend Dorian and Summit Health to anyone who wants to take control of their health and truly understand their body. It has been nothing short of life‑changing.

Thank you, Dorian and Nicola, for everything over the last 12 weeks. I’m genuinely excited to continue as part of the Summit Health community.

i would really recommend starting the program, i was in a real mess with a huge Arthritis flare and was in huge pain, the internet was just sending me round in circles with misinformation, the Program is not the cheapest but i have had full support and given information that i could fully trust, i've learnt a lot about myself and how to look after myself, this course is not for people who can't commit to it fully but its a game changer .. i will be sticking to the principles of the program for the rest of my life, if your unsure just book in for a chat and see how you feel.. good luck..

I felt supported all the way through the programme. Dorian and Nicola's knowledge around autoimmune is exceptional and they really encourage you along your journey. I saw a vast improvement, from being unable to leave the house most days, to taking the dog for his daily walks. It is completely correct that to do the programme you MUST put your trust in the process and put the effort in. You will have dips throughout, but keeping a record makes you see the improvements.

■ I am an ex ward sister, in my mid 60s and was diagnosed with Rheumatoid and Osteoarthritis less than 3 years ago. Before that I led an active life, keeping horses, enjoying gardening and painting, swimming, traveling and walking.
■ Until joining the Summit Health programme just before Christmas 2025, pain and swellings were barely managed by steroids and limited pain killers. Arthritis medication did not seem to kick in. I did much research and tried lots of different things suggested online or in library books to improve things but pain and mobility just got worse.

IT IS WORTH READING EVERY REVIEW HERE ON TRUST PILOT

Things I could NOT do ~
● Walk more than a few steps without assistance,
● Dress / undress as my back, neck and arms hurt
● Do up buttons / belts
● Or do any artwork as my hand and fingers were swollen and sore,
● Walk upstairs to bed as my knees were so painful ,
● Cook a meal, do household chores

My mood was low as I was in constant pain, gaining weight and I felt I was becoming too much of a burden to my husband .
Acupuncture did help short term as did various topical gels , ice packs and hot water bottle, but nothing lasted very long.

I prayed for guidance as there were so many things suggested online and an overwhelming feeling of dread ~ who is real and who is not ? What would work, wasted money or not? (For me, it was NOT wasted as I had trust and the right kind of support)

Have to say I am SO glad to have met online Dorian and Nicola of Summit Health, gone through a programme devised just for me after an initial assessment and lots of forms.
It is not a magic wand, it is hard work, changing habits, mindset and diet.

After 12 weeks , what CAN I do?
● I can walk further without assistance
● Completely wash and dress myself
● Including doing up buttons and belts
● Do more correspondence and artwork
● Carry cup of tea upstairs !
● I can cook a meal without help
● Do light housework and potter in the garden

I have not been prescribed any more steroids since starting and have not needed to take any pain killers for quite a few weeks. I have lost weight despite eating more and am able to go swimming every week in the local pool.

I still have a way to go, but am feeling so much better than before. Am Very pleased with the education, support and guidance given by Summit Health Team.

I recommend reading all reviews and having a look at the Facebook group. It is not for everyone but there is chance to speak about it before having to pay .

I came across Dorian/Summit Health via Instagram, he just popped up one day on my discovery page. All i can say is that he is very knowledgable, extremely passionate and very kind. His 12 week programme is very detailed and the support you get from him and Nicola (his colleague) is second to none. I have worked with a few functional nutritionists over the years but the support and guidance you get is like nothing i've experienced before. He is better than any GP !!!Yes its not cheap but your health is worth the investment. Ive learnt so much from this programme, I would 100% recommend .

I chose to start working with Dorian and Nicola after exhausting all of the medications available to me. The programme gave me options, and for the first time in decades I felt more in control of my health. I was no longer in free fall and I had hope.

I was given the information I needed to explore areas of my health that I hadn’t realised were key to improving my particular issues. It helped me understand my body’s needs in a completely different way. I now have tools that I can use for life.

If you’re willing to take their advice and put in the work, it can be incredibly empowering. I’m so grateful for the knowledge and support they gave me and wouldn’t hesitate to recommend them to others who feel like they’ve run out of options or who need a fresh perspective on their health.

I would highly recommend undertaking this program, as long as you are prepared to make life changes Dorian and Nicola will guide you through, I have struggled for over 30 years with multiple immune sytem diseases and I now know what to do to support my body to have a better quality of life from nutrition, exercise, sleep, stress management things that i would never have considered to try or understood were negatively impacting my health, i have learnt so much for a lifetime to put into practice. You will be supported and have Dorian and Nicolas experience to draw on, I felt supported for the first time by people who really understand, i have the confidence and knowledge now i wish i had 30 years ago, good luck to anyone wishing to try to improve their life and give it your all you'll feel the benefit.

Where to start!
After much searching I found Dorian. From my first point of contact I felt confident that he knew how to turn around my illnesses.
After being unwell for many years and finally developing Graves’ disease I was at a loss. Even as a nurses of 30 years experience I was not able to navigate a way forward.
Dorian and Nicola gave me the skills and confidence to move things forward and turn things around.
I was able to fulfil my goals and enjoy a family skiing holiday and this did not set me back.
I have been able to successfully incorporate the changes I have made into my daily routine around my work and family and have even managed to get my close family onboard with dietary and stress management advice.
I firmly believe if I have not found this program I would have been in a very bad place now.
Instead I fill more fulfilled with a new sense of purpose and I am able to enjoy my life with renewed joy.
Nothing is too much trouble and no question too stupid.
I now understand how to keep myself and my condition on track in the future. But know Dorian will always be there if I run into difficulty.
Thank you for everything 👏🏻

When I felt I had ran out of treatment options with the NHS, Dorian provided me with light in a dark tunnel. Working with him I was able to put my autoimmune disease into remission and come off all of my medication. Dorian is one of the most intelligent, inspirational people I have met. He always has another option which will help, he is a God send.

I came to Dorian at a point when I was very ill, at that point I was pretty much bed bound. I decided to take the leap of faith with him after following him for some time and some serious discussion with my wife.

I can tell anyone who is thinking to give it a go to go for it. It's the best decision I've made, I am not fully in remission but I am certainly a lot better than I was.

I am able to play with my children, to go to the gym for the first time in a long time. My gut issues have massively reduced. Some histamine symptoms I was showing have improved. And Nicola who works with dorian has given me some invaluable knowledge.

Guys if you have brain fog, tiredness, you have internal pains or just generally feeling unwell when the doctors keep telling you your bloods look normal.
Dorian could well be able to help you with the missing piece.

Thank you dorian and Nicola for giving me some resemblance of my old self back!!

I gained so much from working with Dorian and Nicola and would highly recommend. They are both very knowledgeable and helped me work through my Hashimotos recovery. The program is very clear and manageable and both are very responsive to questions or any clarification needed. The plan is to set you on a healthy path for the rest of your life, in terms of the emotional buy in to this and the 'upskilling' on how to do it. Dorian does a free initial chat, to see if you feel this is something that could benefit you. I am UK, but know he works internationally.

I had a wonderful experience working with Dorian and Nicola. I came to Dorian with quite a complex medical history that was flummoxing many experts. I was feeling emotionally exhausted and as if I was constantly battling with my body and that no one would be able to make sense of it. Very quickly, he worked out the root cause of my symptoms, which was later confirmed by testing. There was a fair bit of trial and error with trying new supplements but I knew I could always contact Dorian or Nicola with a question and they would be very quick to respond, reassure me and find a new way forward. I'm still learning but I have a much greater understanding of my body and what I need to do to get it back on track. I really encourage anyone who is feeling overwhelmed and unsure of how to get their health back on track to work with them.

When leaving a review, Trustpilot asks "what made your experience great?" In this case, that would be Dorian and Nicola. Throughout the process they were both always very responsive and keen to help. Whilst not everything worked exactly as intended, they continued to offer alternative solutions.

As part of the course, you are given significant amounts of information about what's could be driving the issues you're facing, but ultimately it's down to you to put in the work and make the most of it. The only change I would make is maybe condensing this information into shorter & less detailed format.

Doing this course has taught me so much I didn't know, most importantly regarding my diet! it's been really eye-opening and I would highly recommend giving it a go!

This was a true collaborative experience between an engaged and knowledgeable health practitioner and a desperate but willing client. I came to Dorian with lifelong gastrointestinal issues that forty years of standard US medical doctors and prescriptions had failed to fix.
We worked together for several months, met on Zoom once a week, exchanged thousands of WhatsApps. Dorian saw me and listened. He thoughtfully crafted a plan that included very informative videos/lectures about the mechanics of the digestive system and the many causes for its deregulation. It was fascinating to finally SEE and UNDERSTAND this complex system - no doctor had ever bothered to explain this to me as fully and effectively as Dorian did. It all made perfect sense.
We worked on goals, education, diet, hormone levels, exercise (prepare to work!), nutritional supplements, weaning off Proton Pump inhibitors, etc. At the end of our time together my lifelong IBS and Acid Reflux were all but GONE and my protein/muscle mass was up. Truly a miracle in my life.
Dorian is uniquely qualified having suffered his own medical issues that failed to be fixed by single-focused, standard medical practices. He gets the hopeless, confused, frustrated client - and he is remarkably knowledgable, effective, kind and just a great cheerleader. If you are prepared to work, follow the program, be patient and realistic then Dorian is the person to help restore your health and quality of life.

At the start of the year, it seemed like every job I went to I would be getting ill. I am an electrician and if I worked in a damp location, I would have a reaction. This would cause something in my chest to change and any food that I consumed that evening would become stuck. My only option was to vomit to remove it from my chest.
Over the past ten plus years I have been to the doctors many times and to the hospital for the camera down my throat twice, to be told it’s all normal. Then to be prescribed omeprazole of increasing strengths every time I went back. This medication did not improve my situation. Doctors were telling me that what I was describing could not happen. They could not help me.
Over time my diet became increasingly limited as I seemed to be having reactions to all different foods. It was also affecting my mood and causing me anxiety, to the point where I would no longer go out for a meal or on holiday.
I am self-employed and was considering starting to look for a job doing something different, every time I answered the phone to a potential customer, I would be thinking is this job going to make me ill and I was dreading the phone ringing.
For the past year or so, I had been working with a nutritionist and gone gluten and dairy free. Only eating whole foods and had a healthy diet but i seemed to be getting ill every week. It was a desperate situation. Allery experts’ advice was just to avoid those situations. i thought this was it for me, for the rest of my life.
I came across Dorian and Summit Health online and decided to have an online meeting with him. During that meeting, I decided that I wanted to work with him, as he said he thought he could help me. The way he explained things just really connected with me and gave me some hope.
Dorian’s program made me understand and learn so much, his detailed information leading you every step of the way. You may have been told these things before but not understood the value and importance of what you have been told, he has a knack of getting the information across and I had absolutely no doubt of what I needed to do.
It’s been about twelve weeks now and I have not been ill; I have been on a plane (which a hypnotist could not help me with) on holiday and managed to eat out every night. It’s completely changed my thought process. I now have so many tools to deal with and enjoy life so much more. I feel so lucky to have been on Dorian’s program.
I never give reviews but feel with this I must, as it has changed my life so much for the better. Just look at his testimonial videos, all real people with amazing results. Have a look at his Facebook group and the amount of free information he provides on there.
My advice would be to just give him a call, he may be able to help.

Dorian is a thyroid wizard!

Having been through his own thryoid journey he has empathy and practical experience. Using a logical and well thought out approach, (he has a degree from Durham uni before his journey started) means you can challenge him allowing for open and personalised conversations. He was the perfect compliment to my western medicine input and in the end I got exactly what I wanted which was to be well enough for the IVF clinic to allow me to restart trying again. The bump and I am forever grateful!
