About
Chiang Mai University is the common thread in Dr. Chanchai Sumonwong’s training and early career: he earned his M.D. there, served as a staff physician at Suanprung Hospital in Chiang Mai, and then completed specialist practice at Phramongkutklao Hospital — Bangkok’s large military-affiliated teaching hospital — before moving to his current obstetrics-gynecology post at Phyathai Sriracha Hospital (career sequence per his ZeekDoc physician profile; the official Phyathai CMS biography fields are empty).
He holds a Diploma of Fellow in Obstetrics and Gynecology from Phramongkutklao Hospital and an advanced medical science certificate from Mahidol University (per the same third-party profile). At Phyathai Sriracha he appears in the hospital’s Obstetrics & Gynecology doctor directory, the department that feeds the hospital’s Infertility Treatment Center with gynecologic diagnosis, workup and pregnancy care.
As with most physicians on Thai hospital chains’ English sites, no publications or procedure counts are published for him; patients comparing doctors should request details directly through the appointment line.
