The doctor and the staff at the clinic are very kind.

and a colleague recommended it. For those who don't have many days off or have fixed days off, I highly recommend this place.
Conveniently located near home...it doesn't take long to get there.
Good service, the doctor and staff are very nice and speak very well.
The doctor took excellent care of my case. The other staff members also provided great advice and showed great care for the patients.
The service was terrible. They even gave me the wrong change. I had to transfer the money back to them. This is the last time I'll ever get my money back.
I'm not a customer, but I was walking by when the clinic splashed yellow liquid out the second-floor window, which hit my head. The Siam security guard also looked up and then closed the window as if nothing had happened. Stop being so selfish if you want your business to flourish. Splashing some kind of liquid on the heads of passersby is itchy, too.

We apologize. The clinic would like to request additional details to investigate the branch staff. This is because the Siam branch does not have a window on the 2nd floor. We sincerely apologize.
