April 08, 2020
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.

Doctor and team were great
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!!!!

FOR SUCH A PERSONAL MEDICAL PROCEDURE, THE DOCTOR IS A VERY UN PERSONABLE PERSON. WE MAY HAVE SAID 20 WORDS BEFORE MY PROCEDURE.THE STAFF WAS WONDERFUL AND A PLEASURE TO HAVE DURING A SENSITIVE PROCEDURE, THEY WERE ALL SO NICE AND HELPFUL, AS FOR THE DOCTOR, HE ASKED ME A QUESTION THEN WALKED AWAY BEFORE I GAVE HIM MY ANSWER. NOTHING POSITIVE TO SAY ABOUT HIM EXCEPT I FELT NO DISCOMFORT AFTER THE PROCEDURE SO HE MUST HAVE DONE A GOOD JOB.
