    Dr. Hazan is very knowledgeable and a great doctor. He diagnosed me in AFib during a visit and sent me to the hospital. I was, in fact, in AFib and have been treated. A few weeks later, I had a colonoscopy by Dr. Hazan. His bed side manners were impeccable and put my mind at ease. I would definitely recommend Dr Hazan.

    I believe Dr. Hazan is absolutely the most wonderful person in his field. I trust him and his judgement 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 autoimmune disease and developed UC unknowingly. I had some huge trepidation on having colonoscopy and along came Dr. Hazan. After the first time consultation, he had me booked in less than a week for colonoscopy and endoscopy. He was attentive to my worries, explained in detail the process, addressed my autoimmune and had a genuine caring concern. Fast forward to now, Dr. Hazan diagnosed me and provided me with a full treatment program. I have never felt better than now. I’m very grateful to Dr. Hazan and the professional staff.


    Mr. Ohlenkamp is very thorough and is very 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.
