Yevgeny A.

"THIS DOCTOR SAVED MY LIFE. I came to her after going to another GI who ran no tests on me and when I told him I couldn't eat and was in pain he said maybe that's not such a bad thing". Being plus sized I was shocked and searched for a female doctor. She ran all the tests and they found a large tumor in my colon. I was admitted and she came to explain everything to me while I was in the hospital. Today I am leaving her office thanking god put this angel in my path because I have colon cancer. She did more then her job. She treated me as if I was family. I'm so so very grateful for her."

Dr. Haq & her entire Anaheim staff answered all my questions, kindly, was very informative and put my mind at ease. When my appt. came, everyone was wonderful and professional. Through the entire procedure, from 1st appointment to finish they had a way of making you feel you were their only patient! I I wish all doctor's and staff were like this! I would recommend Dr. Haq and her entire staff to everyone!"

If you need an excellent GI Doc in the Anaheim/Garden Grove area, I would highly recommend her. Not only is she highly intelligent in her field of medicine, but also one of the most compassionate, kind and caring Doctors I have ever seen. She is beautiful outside but, more importantly, on the inside. She truly cares about her patients. Her staff is very accommodating as well. Please go to her if you're ever in need of a GI Doctor. Thank you. Dr. Haq!"
