Phoenix, AZ |
Quiet, efficient doctor and a pleasure to see. The whole family goes to him.
Texarkana, TX |
I really liked Dr. Leff. He is the one doctor who was able to help me with my digestion problems. He seems to genuinely care and takes time to figure out the problem and come up with a solution. Five stars for him!

Dr Leff has an over inflated ego which effects his job performance. His staff member "Kimmy" is a lazy inaficient liar. This was a HORRIBLE experiance
in Chandler, AZ |
Waited 3 days in hospital before he saw me despite a rather urgent issue. He shook me awake and immediately started to interrogate me without waiting for me to wake. I told him a local ER had sent me to the hospital for specific tests. He said, "No, they sent you here to see ME." Epitome of arrogance. When I described my medical history he laughed. Tried to correct me about my own life. When I challenged him, he said we weren't a good match. I agreed. NEVER trust a Dr. that doesn't listen!
Chandler, AZ |
Dr Leff came to my room for a consult on a very complex GI issue. He argued with me about my symptoms, did not offer any assistance and I was glad to see him leave the room.
in Mesa, AZ |
I just met Dr. Leff in my hospital room waiting for an operation. I'd never met or heard of him before but he started questioning me about my conditions and other doctors. Said he KNEW ALL THESE GUYS and was working with my surgeon . Didn't have a business card and refused to produce any ID. Tried to lift my shirt (gown) and examine me without asking. Became offended at my skepticism; fact he was accompanied by hospital nurse was supposed to be all I needed. VERY weird experience.
