When you have diarrhea that won't stop you don't want to wait weeks to get an appointment to stop this mess. Got to see his assistant and what she subscribed didn't help.

February 19, 2020
Make an appointment and you will be seen in a very good timely manner. Dr. Lah is an excellent surgeon and his diagnosis is always right on. If you want a "bandaid" for your medical issue, go elsewhere. If you want a 'cure or treatment', please go to PIH and see Dr. Lah, Gastroenterologist. Thank you!!!!
February 19, 2020
What PIH can improve is the telephone system. It takes too long to talk to a real person!
