About Tangchitnob MD

Timeless Health MD, by Dr. Tangchitnob, is a technology-integrated consumer-focused functional medicine practice offering in-personal and virtual care. We aim to offer customized care through a blend of human-centered office visits, technology, and an exceptionally trained team. Our patients enjoy seamless access to annual screening visits, hormone evaluations for those undergoing menopause (and andropause for men), effective medical weight loss programs, and minimally invasive face and body aesthetics treatments - all performed on-site in our large, state-of-the-art Timeless Health Procedure room. Located on Emanate Health Queen of the Valley campus, our office is conveniently located in West Covina, where more of our board-certified robotic surgeons perform advanced endoscopic procedures - should you need them using the latest Da Vinci XI system.
Timeless Health MD's patient experience is powered by intelligent uses of technology, including the incorporation of Phreesia, which helps new patients on board to our practice, schedule appointments, and check in to the office digitally - all without the hassle of traditional paperwork. Consistent, quality care is ensured through up-to-date digital health records with Allscripts Professional. So, if you can't make it to the office, Timeless Health can make access frictionless with face-to-face care over video chat. 
The team offers the latest in plant-based bioidentical hormone replacement for men and women using high-quality BioTE pellet therapy, advanced robotic surgery for hysterectomy, pelvic floor reconstruction and ovarian cysts, body sculpting with Beautifill Laser Liposuction/Coolsculpting and advanced facial injectables with Juvaderm, Botox and Mint PDO threads.
