John D Leff

Dr Leff was super kind and explained my surgery thoroughly. He has the best bed side manner and made me feel more relaxed going into surgery knowing he was the surgeon! Thank you, Dr Leff, for being compassionate and so caring.

I call him my nice Dr House. He has literally saved my life twice. Great diagnostic doc and great surgeon. Does his research and helps. He’s honestly a nice guy too and I always have hope after seeing him. Oh, he’s not quick to cut either which is nice for a surgeon. Ask for him if you are at Riverside.

Dr. Leff is a fantastic doctor! His office staff and nurses are very helpful and friendly.

Dr. Leff has been my surgeon twice: once for gallbladder removal and in April, 2018 for hernia repair. He is very professional, personable, and explains the procedures clearly and in language understood by his patient. I would highly recommend him.

I had appendicitis, ruptured. I can not say enough about the wonderful care I received. Being from Arizona and in Ohio and needing emergency surgery was very scary to say the least.

I am beyond blessed to have been referred to Dr. Leff. My daughter has been battling issues for a year and we could not find a doctor to listen to us...he actually LISTENS to the patient. Tests are not always 100% accurate sometimes you have to listen to the patient and their symptoms to know the problem. Amazing!

Dr Leff is a good surgeon. He is however a part owner of the Knightsbridge Surgical Center. My wife had hernia surgery two weeks ago. Today we received a bill for $16,000 for facilities use, reduced to a little over $2,000. Who paid the difference. Dr. Leff did not let my wife know he had a financial interest in the surgical center, a violation of medical ethics. The facilities use fee is separate from any other charges. Michael B Fiske

Dr. Leff saved my life...twice between 2010 and 2012.. He also left me with functioning kidneys when others were recommending more precipitate action that could have rendered them useless.

Great guy....but you can arrive 40 minutes late for your appointment and still be early. All in all a very laid back doc with excellent bedside manner. Like all docs- they could be a little more forthcoming with information for patients and after care instruction but that seems to be the way it is with everyone these days.

Never have I felt so comfortable speaking with a surgeon. He listened and performed services as promised. He's great with "at risk" patients like myself. If you need surgery, he's the guy to have do it.

Dr. Leff is a great surgeon with great people skills. He is a good listener and provided an excellent explanation of my surgical procedure and what I could expect afterwards (which was spot on). He answered all of my questions related to the surgery and didn't give the impression that he was too busy to spend time answering them. He actually remembers you at your follow-up visit. I would recommend him to anyone.
