Meet Sarah
The clinician who connects the dots others miss.
I'm Sarah Belcher — physiotherapist, functional medicine practitioner, and certified health coach. After 26 years working in both the NHS and US private practice, I kept seeing the same pattern: brilliant, driven people being told their labs were “normal” while they felt anything but.
Fingerprint Wellness exists because healthcare should be as individual as a fingerprint. I help you understand the bigger picture, identify what matters most, and create a clear path forward — whether that means foundational lifestyle changes, advanced testing, or connecting you with the right specialists.
Whether you're in California or the UK, I work with you to interpret your data, build your plan, and guide you through real, sustainable change.
Personal care. Practical guidance. A clearer path forward.

“I sought Sarah out after feeling dismissed by my primary at Kaiser and being told everything was fine when it was the exact opposite. She sent me a thorough questionnaire before we even met, asked for all my labs, and the first meeting was two hours going over everything from birth to now. With Sarah's help, I'm starting to feel like myself again.”

“There are not enough words to thank Sarah for her knowledge, care and expertise. Her work has given me my life back and more, and I am so grateful. You feel very seen and cared for. She listens very deeply and is devoted to helping you thrive again. Her wealth of knowledge and encouragement gives you confidence you will heal.”

“Within 1 session I had a game plan on how to start tackling my issues. She's so knowledgeable — anywhere else would have taken a team of people in different fields to come up with all-encompassing solutions. Each visit I walk away with new knowledge, education, and practical exercises. After visiting multiple doctors, seeing Sarah was the first time I started getting results.”

“Working with Sarah has been a game changer. She taught me how important strength training is — at any age — and my blood sugar has lowered significantly. She taught me how weight training moves sugar to the muscle, not my blood. She listens, encourages and empowers. Can't recommend her enough to anyone who wants real results in an approachable way.”

“Sarah is so knowledgeable when it comes to supplementation and gut health. She got me on an amazing supplementation plan that healed up my gut within 3 months. I felt so much better and my skin improved so much — I have never felt so good! I'm so lucky I found her.”

“Her approach is thoughtful, personalized, and focused on getting to the root cause rather than just treating symptoms. I felt heard, supported, and guided every step of the way. The functional approach made a huge difference for me, and I finally feel like I'm on the right track with my health.”
