Dr. Kumar is an excellent GI doctor, both my daughter and I see him. I had suffered with chronic diarrhea since 20 years of age and 37 years later he was finally able to get to the root cause of it and I feel like a new person. My daughter is doing so much better as well and really glad he was able to diagnose her properly at her age (22) so she didn't have to go through what I went through for years.

Dr. Kumar is the best doctor I have ever seen. He is intelligent, kind and very compassionate. He is very committed to proving excellent, timely care to his patients. I seriously have never gotten an MD or test appointments so fast. If a patient needs to be seen sooner than the average wait time, he makes an earlier appointment happen. I had a test done and he called me by the end of the day to discuss the results. What more can a patient ask for? I wish he could be my doctor for everything.
