Patient Comments (9)
Houston, TX |
Dr. Umoh provided quality care and has a wonderful bedside manner.
in Tomball, TX |
Great experience considering I was in extreme pain and looking for help when I made the appointment. Dr. Umoh and his nurse Elizabeth went out of their way to make me comfortable and to preserve for me at least a shred of dignity (given the area they were working on, if you get my drift). The procedure performed in the office gave me near instant relief, relatively speaking, and healed well. They followed up the next day to check on me and were available to answer questions by phone.

Dr Umoh is an awesome surgeon. He took care of my hemorrhoids. No more pain from hemorrhoids! He is highly recommended.
in Houston, TX |
He preformed MAJOR surgery on my Dad then left the practice. We had to see his old partner who thankfully was a great doctor, but he was unprofessional just to leave like that. He could care less about his patients, and didn't even let anyone know where he was going. HORRIBLE QUALITY OF CARE!!!!
in Sugar Land, TX |
Dr. Umoh is, hands down, among the best physicians and specialists who have treated me. He is extremely skilled, with great bedside manners and attention to detail. He has a very high level of empathy for his patients and their loved ones, which is something that was greatly appreciated by my family while I was under Dr. Umoh's care. I am fortunate that my PCP referred me to Dr. Umoh.
in Houston , TX |
Dr. Umoh was very professional and he explained everything to me. I would highly recommend him ,He was very kind and to the point. He made me feel safe and that I was being heard. He knew exactly what was wrong and treated it immediately. I'm back to 100%. Wonderful practice and would certainly recommend.
in Houston, TX |
Excellent service, Dr.Umoh took his time to thoroughly explain my condition to me, he also explained the proceedure to me in a very clear and simple manner. Follow up visits were very easy to schedule. For the first time in 5 years, I feel really better.
in Houston, TX |
Dr. Umoh was very great to me during my initial consultation. He is well versed in the Colon & Rectal surgery specialty. He also showed compassion during my visit and discussed options to help me decide the best course of treatment. I will recommend Dr. Umoh without any reservations. Mr. Paul D.
in Houston |
Dr. Umoh showed a lot of professionalism and compassion to my sibling. Starting from the wait time at the office, up till the post- op visit was an excellent experience. He explained the diagnosis and made it easy for us to understand. I will definitely recommend Dr. Umoh to my family again. He was very compassionate and he listened.
