Dr Leff's staff is professional, courteous, efficient, supportive. I can't say enough good about Dr. Leff who has been caring for me since my diagnosis of rectal cancer 3+ years ago. He takes the time to address all of my questions and concerns, does what is an embarrassing uncomfortable exam quickly and efficiently and is reassuring and supportive. The office is calm and I never feel rushed. Dr Leff is a part of the team that treated my cancer and I am now 3+ years cancer free. I feel that every day is a gift and I am forever grateful for my oncology team at Midstate.

Dr Leff and his staff were all wonderful. They are amazing efficient (never had to wait even 5 minutes) and they are so genial. I told Dr. Leff I wanted to work there because everyone seemed so kind and joyful. Dr. Leff's personality helped allay any fears I had going there for small surgery. All around, it's a great practice!
