The Doctors

Two physicians. One philosophy.

Healthi Life is doctor-led, not doctor-on-call. Every protocol and every recommendation carries the name of the physician who prescribed it. The two co-founders work the same way: measure before deciding, understand before acting.

Longevity Programs

Dr. Sarassawadee Suwanjinda, MD (Petch)

Longevity & Functional Medicine Physician
Co-Founder Β· Chief Medical Strategy Officer

Dr. Petch leads the Longevity Programs at Healthi Life. She is a longevity and functional medicine physician trained at Davao Medical School Foundation, Philippines (MD, 2016), holds Thai Medical Council License No. 63464, and is a Diplomate of the International Board of Lifestyle Medicine. Her approach is guided by the analysis of up to 300 biomarkers across six pillars of biological aging, with quarterly reviews and monthly physician follow-up. She reads the biology first and builds the protocol around it, so a guest knows which system to act on and in what order.

About our physicians

Credentials, licensing, and who is responsible for your protocol.

Who will actually treat me at Healthi Life?+

One of two physicians, both co-founders. Dr. Petch (Sarassawadee Suwanjinda, MD) is Chief Medical Strategy Officer and leads the Longevity Programs and Advanced Check-Up. Dr. First (Napat Hunsajarupan, MD) is Chief Medical Officer and leads Recovery & Performance Medicine. The physician responsible for your protocol is named before you commit.

Are the doctors licensed to practise in Thailand?+

Yes. Dr. Petch holds Thai Medical Licence No. 63464. She earned her MD at Davao Medical School Foundation in the Philippines in 2016, and interned at Police General Hospital and Ananda Mahidol Hospital, Lopburi. Dr. First earned his MD at Thammasat University, with an MSc in Dermatology from CICM, Thammasat, and previously served as a General Practitioner with the Royal Thai Army Medical Department.

What are their qualifications in longevity and regenerative medicine?+

Dr. Petch is a Diplomate of the International Board of Lifestyle Medicine (IBLM), certified in cellular therapy by the International Society for Stem Cell Application (ISSCA), holds CBAM certification from the Certified Board of Anti-Aging Medicine, and is a member of the American Academy of Anti-Aging Medicine (AAAM). Dr. First holds AAAM, the Practical Cell Therapy Symposium, H.E.A.T. (Hormone, Endocrine & Anti-Aging Training) and Integrative Dermatology.

Which doctor should I see for which treatment?+

Dr. Petch for longevity programs, advanced check-ups and biomarker work. Dr. First for recovery and performance medicine, skin, and peptide protocols. If you are not sure, the consultation sorts it β€” you are not asked to choose before being assessed.

How many biomarkers does a longevity program actually measure?+

Up to 300 biomarkers, across six pillars of biological ageing, with quarterly reviews and monthly physician follow-up. The exact panel depends on your program and what the first results show.

Does a physician decide whether I am eligible before any treatment?+

Always. Eligibility, medical history, current medication and contraindications are reviewed before a protocol is offered, and the answer is sometimes that a treatment is not appropriate for you. Stem cell and regenerative protocols are investigational; outcomes vary and are not guaranteed.
