My family has been going to Regency for over 15 years. Doctors Aziz and Patel are wonderful. The medical assistants are kind and caring. If you are in need of a diagnostic and knowledgeable primary physician Dr Aziz is simply the best. He’s kind, caring, listens to concerns, explains his approach, and answers any questions you have. He does not refer you to a specialist unless it’s necessary, explaining the tests he’s ordering and why. He can save you an extra appointment for an X-ray or ultrasound at times. If you are in need of an emergency appointment he will get you in. There’s a reason he has a lot of patients, GREAT QUALITY CARE, it’s hard to come by. I agree waiting is frustrating but once you, or a family member, need that emergency appointment you’ll be grateful. When you have a serious health condition, you’ll wait to see the best.
