Katz Gregory MD

The best referral I ever received was the introduction I received some 30 years ago that brought me to become a patient of Dr. Katz. Through sickness and injury never once was I anything but grateful to have been treated, cured, and healed by such a brilliant and caring person. I hold him and his staff in the highest regard and congratulate every new patients lucky enough to have found him.

Dr Katz takes care of my elderly mom, as well as many family members and friends. He is extremely thorough, caring, and doesn't rush you through an appointment. I am thankful for his expertise and thoroughness.

Dr. Katz has been my doctor and my husband's doctor for over 25 years. He is always on time; he listens; he provides detailed information; and he cares. He is a wonderful doctor and a good person. The girls in the office are friendly and fun. I look forward to going and seeing everyone.

Dr. Katz is a marvelous doctor who is timely in keeping your appointments, takes plenty of time with whatever you need and is extremely thorough. Until I found Dr. Katz, I would drive all the way to Cedars Sinai, where I had a doctor who I had seen for many years. I feel very lucky to have found Dr. Katz in Orange County, and I would most highly recommend him.

Worst experience with a physician ever. Dr. Katz has zero bedside manner nor does he acknowledge the patient seated before him. He is my elderly father's doctor. At each visit, this so-called doctor barely acknowledges my father, only speaks to me, and treats my father like a piece of old meat. Poking him with disgust. My father is very jovial, and pleasant and no patient EVER deserves to be treated in this manner. Katz is unapologetic about his treatment of my father, and was "appalled" when I brought his lack of care for my father when to his attention. Very disappointed with his care. I am in the process of switching doctors to remove this unprofessional and unsympathetic individual frommy dad's team of care.
