Needed a check-up for a new insurance policy. Found Dr. Possathorn online. Appointment was straightforward. He was efficient, asked the right questions, didn't waste time. Got my paperwork sorted quickly. Exactly what I needed.

I was really worried about some ongoing stomach issues. The hospital is big and I was nervous at first, but Dr. Possathorn was very calm. He listened quietly, explained things in a way I could understand without being scary. He ordered some tests and called me himself with the results. I feel much more at ease now.

Oct 12, 2025

After moving to Bangkok, I needed a reliable GP. Tried Dr. Possathorn at BPK 9. Parking was a hassle, I'll admit. But the visit was great. He's sharp, remembered details from my file at the follow-up. Fixed a lingering cough two other doctors missed. Really glad I found him.

Dec 29, 2025

I had a bad fever that wouldn't break. Went to the emergency department at Bangpakok 9 and Dr. Possathorn was on duty. He was direct, clear about what he thought it was (turned out to be dengue), and laid out the plan. No sugar-coating, but he was kind. The nurses were great too. Recovered fully. Huge relief.
