I had reached a severe low point in early 2021, post-pandemic, having already suffered several years of ill-health. I realised I didn’t have the required knowledge and expertise to tackle so many symptoms on my own, especially as I was feeling demotivated, deflated, tired and on top of all of that I had been dealing with insomnia for 18 months. Zara Wilkinson was reassuring, patient, kind, understanding and motivating. For the first time ever, I felt I had someone in my corner, someone who didn't treat me like a hypochondriac or look at me and say "...But you look so well?". It made such an impact to feel like I could count on someone to be there when in need, aswell as to have someone validate my struggle, and recognise and praise all of my work and efforts. Not only does she have such lovely personal characteristics but professionally she’s quick to respond, super knowledgeable, and insightful across a range of topics, and she's continuously expanding her knowledge, undertaking courses and workshops, and broadening her skill-set. One of my favourite things about Zara is that she's conscious of how clean a supplement is prior to recommending it - it's one less thing for me to think about. In short - Zara is incredible. I’m so happy to have come across her, I cannot praise her highly enough, and I’ve already recommended her to many of my friends and family. I’d highly recommend Zara if you’re looking for an expert to help you with your journey. Someone that can really process and make sense of your symptoms, lab results, and lifestyle factors. Thank you Zara, your time and effort have meant more to me than you will ever know, and will continue to do so.

I’d been unwell for many years when I approached LCON – all the team there are caring and very helpful. I took out a care package and had a series of appointments with Dr Oliver Barnett. He always listened carefully to what I had to say, and it was his flexible adaptable approach that turned my life around – literally. (I don’t say that lightly!) In a nutshell, I have mould toxicity issues, a leaky gut as well as other related health issues, but I’m now well on the road to recovery. My life is no longer on hold and I can plan for the future – so a huge thank you to Oliver and the LCON team!

Came across LCON after watching a video that Oliver did on the treatment of Lymes which made it clear that they understood the treatment path. Super experience with LCON, any healing process is slow & somewhat complex, but Paul Foleys advice has always spot on and 100% trustworthy. Highly recommended

One of the best decisions I've ever made was coming to this clinic. I decided to to see Oliver Barnett about four years ago with skin issues and just an overall feeling of being unwell. Within weeks of changing my lifestyle a bit and taking some recommended minerals and vitamins, I was on the road to feeling like myself again, my younger self:) I still refer back to his advice to this day. I have sincere gratitude for this practice.

I am so thankful to be working with Oliver. I have had digestive issues that I had been living with for over 15 years. Since working together with Oliver, all my digestive issues have subsided to a point where I feel like I am in my 20s again. I used to have painful swelling in my breasts before my periods, and used to have adult onset acne on my face constantly. Those too, have subsided. My skin is clear without using anything topically, and do not need to wear foundation, or tinted creams. I guess you really are what you eat. I had tried many routes and eating plans before over the years but had not gotten results close to the ones I am experiencing now. This has been brilliant and will definitely keep a long term relationship with Oliver.
