Dr. Marie Bailey
The most rewarding aspect of practicing gastroenterology for me, is the ability to use my skills to help my patients. There is also significant opportunity for prevention. I hope to communicate to my patients the true privilege I feel in caring for them.

testimonials

My Experience with DR. GERALD BERTIGER
Dr. Bertiger and the Hillmont Staff provide OUTSTANDING, PROFESSIONAL and VERY HIGH QUALITY Medical Service which on scale of “10” are rated at least an “11”.

My Experience with DR. VICTOR ARAYA
Dr. Araya spent time with me explaining everything. I never felt like he was rushing to get to the next patient but felt he was trying to make sure I understood what was happening. I highly recommend Dr. Araya.

My Experience with DR. STEVEN NACK
Dr. Nack is an astute physician with an excellent bed-side manner. He is a person who actually connects with the people he sees, and is happy to redirect them to other places when it is a matter that he cannot handle. I give him 10 stars out of 5.
