I have been one of Dr. K.T. Marks' patients for over 5 years. I highly recommend him along with his staff. They are all a very professional, knowledgeable and a considerate, caring and genuine team. Never a long drawn out wait. Whenever I have come to Dr. Marks, he takes his time with me not rushing to get to the next patient. I really appreciate that and so will you! Paul Franek

I have been going to Dr. Marks for about 2 to 3 years. He has been an excellent Dr. and has great staff. I have had an instance where I needed assistance ASAP he was very accommodating. I wouldn't hesitate to recommend him to anyone. The office visits are hit or miss as far as time wait but I don't think that is unusual.

Dr. Marks is very kind, friendly, and courteous. He has always given me the time that I needed and answered all of my questions. The wait was about the same as my other doctors. This indicates that he must be trusted by a lot of people because he is a very busy doctor!As for those of you who are upset that he did not give you the results right after surgery, all he can say is that it went well. He does not know the results until he receives them.

Had Endoscopy and Colonoscopy. He left without going over the results with me saying he didn't know i wanted to hear anything from him or that my son who was in the waiting room wanted to. Is he dumb? he is an experienced doctor and he didnt think my son and I wanted to hear about my results from him? so he instructs us to make an office appointment with him next week... I will make an appointment, but with another doctor. Never seeing him again!

Dr Marks is amazing. Very caring and compassionate. He took the time to listen to my concerns and address them
This has to be the worst dr office and they are all about money...the doctor is saw is Kevin marks. Whenever I call the office, nobody ever picks up. I always get a voicemail. I had a procedure done and after the procedure, he never explain to me the results or findings...A good doctor will normally talk to you after the procedure but he did not. I had to wait for my biopsies. Then two weeks later a lady called me regarding my biopsies who was very rude and did not know nothing. She said to tak

Short, impersonal visit time. Left waiting for long period of time post endoscopy for any results.
