- I saw Dr Raja virtually for stomach and immune system issues and, after having undergone testing, have identified the underlying problems, which has been very helpful. I would recommend Dr Raja.
- Dr Nicki Gill is an extremely knowledgable functional medicine dr who has empathy and the skill to create a treatment plan that targets the issues. She ensures her presence to support you along that journey in available online and via email which really supports the patient. I was in safe hands throughout and could not have asked for a better dr than Dr Gill - if only more drs were like her!
- It has been such a relief to find someone who can connect all the different symptoms and explain the root causes of what my daughter was struggling with. After 5 years, it all just makes a lot of sense. Dr Gill has offered tests and then solutions that actually address the underlying causes rather than just attempting to treat the symptoms. If the traditional 'medical' route isn't working for you, this is definitely worth a try.
- Dr Rajah has a wealth of knowledge and a strong support network. Kind and thoughtful, she listens to your needs and acts upon them with the greatest of care. Thank you for all your help so far in my journey to optimal health :)
- I am incredibly grateful to the functional medicine practitioners who helped me identify the root cause of my health concerns with such clarity and efficiency. Their thorough, insightful approach gave me a real sense of understanding and confidence in how to move forward. I would highly recommend them to anyone feeling uncertain or overwhelmed about their health.
- Dr Rajah took time to fully understand all my symptoms, which really improves my confidence that I can finally resolve my symptoms. I would highly recommend.
- Great at finding the route cause of my problems. Professional and friendly. Would highly recommend!
- Thorough analysis and consultation that leads to an individualised and very effective plan for my health! Highly recommended! Thank you Dr Meera ❤️
- Very happy with service and treatment.
- Couldn’t recommend more, kind, professional, caring and goes above and beyond to fit us in on short notice.
