Patient Comments (15)
Dr. Kumar's diagnosis and the medicine prescribed truly changed my life. I feel 100% better, and am very confident in this doctor. The staff is so nice and caring. I had an issue with my insurance, and they were all very helpful in resolving my problem, including Dr. Kumar. I have never experienced that much interest, and resolve at any doctors office. Excellent experience.

Dr. Kumar is an excellent doctor. He listens to my issues and finds way to help me. His staff is friendly and are on top of getting what I need when I need it. My appointments always run smoothly and I never have a long wait. I highly recommend him for any GI issues.

All these reviews are right on point. Dr. Kumar is terrific. He connects to you in a very respectful way and is clearly a highly skilled professional. I was referred to him by a co-worker with similar reviews. I can't speak highly enough of him.
Crown Point, IN |
Dr. Kumar was absolutely wonderful! Very compassionate and patient. I am recovering from four spinal surgeries and he was great preparing me for a colonoscopy. Wonderful bedside manner, great explanation of findings both immediately after the procedure and follow up appointment. Thank you.
Crown Point, IN |
A wonderful doctor! Was so happy to find a personable and knowledgable gastroenterologist. Sensitive to any issues or problems. Meanwhile, he is up to date with the newest therapies.
Naperville, IL |
We are extremely likely to recommend Dr Kumar. Several family members already go to him.
in Crown Point, IN |
I was referred to Dr. Kumar for an issue concerning my throat. As with any issue not being solved by my family practice doctor, I was a bit alarmed. Dr. Kumar's excellent bedside manner put me at ease from the start. He was very good at explaining what his testing would be and after he performed the scope procedure gave me an in depth review of the results along with what I would need to do to address my condition. I would without an hesitation recommend him his fine staff of Vanessa & others.

Really listens to patient's concerns & questions & takes the time to explain in a way you can understand. Very thorough and excellent rapport with his patients. Highly recommend!
in Lansing, IL |
Excellent physician. He always takes time to explain, in detail, what is the problem(s) and goes over all actions so you don't feel pressured to do anything. That is important.
in Schererville, IN |
I was referred to Dr Kumar by my regular doctor and he preformed my first colonoscopy on June of 2016. His reputation with the nurses and staff at the hospital is nothing short of remarkable. In the short time that I have gotten to know Dr Kumar, I have found him to be straight forward and caring. I would recommend him to anyone that needs his services.
Madison, WI |
Dr. Kumar was dismissive off my symptoms and unhelpful about how to recover from my serious GI problems simply because he couldn't see anything obvious during the colonoscopy. His clinic seems to be run to maximize profit. Overbooking patients a on rare office visit days and focusing on doing scopes for new patients which pays more.
Crown Point, IN |
I had issues for over 8 years that no one had answers for. I saw numerous doctors that could never give me a decent answer to my symptoms. Dr. Kumar was able to successfully diagnose me with an uncommon disorder within a few visits that none of my previous physicians or specialists had even mentioned. He's very friendly, knowledgeable, and easy to talk to. I cannot be more thankful for Dr. Kumar.
