    I believe Dr. Hazan is absolutely the most wonderful person in his field. I trust him and his judgment with all things that go wrong with me and my husband. After all, people need to trust your doctor. I will recommend Dr.Hazan to everyone I know who needs his expertise.

    I have been battling an autoimmune disease and developed ulcerative colitis unknowingly. I had some huge trepidation about having a colonoscopy and along came Dr. Hazan. After the first consultation, he had me booked in less than a week. I have never felt better. I’m very grateful to Dr. Hazan and the professional staff.


    Mr. Ohlenkamp is very thorough and is capable of providing diagnostic care for patients. He does not hesitate to confer with the gastroenterologist if he needs to confirm results with the doctor.
