3 days out of surgery and I feel a thousand times better! Insane to think but anyone suffering with fissures and so on seek help for your embarrassing torture. He did such an amazing job, I felt extremely comfortable with him and I couldn't have expected such immediate results right after surgery. He took amazing care and orchestrated the surgical room perfectly before I passed out. Even what I was most scared of in reality felt like a breeze.
Don't ignore your pain anymore there are professionals who can help and Dr. Leiboff is the one! He also performed just enough for my problem and was very careful to diagnose me for surgery, which I promise you is NOTHING/ NADA in comparison to a fissure!

I found Dr. Leiboff to be an expert in his field and not too quick to recommend surgery. He is very patient in answering all questions and providing detailed information on available options. Both he and his office call to follow up to see how I'm doing. His staff are friendly, helpful, and went out of their way to make me feel comfortable during and after my illness. I always recommend my family and friends to Dr. Leiboffs practice knowing they will get the best care available.

Report
I just completed my last session with Dr. Leiboff and am very pleased with the treatment and outcome! I came to him with what turned out to be a very painful perianal abscess and complicated fistula which he immediately ascertained and proceeded to treat. Dr. Leiboff performed out-patient surgery on me and used his years of experience to properly correct my condition. I am now pain-free and very grateful for his expertise! An excellent Colorectal Specialist and Surgeon in our area, he is a serious and "no-nonsense" physician who listens patiently and gives all alternatives and recommendations for your particular problem.
His excellent and caring staff made my visits that much more pleasant all the way to the last day. Paperwork and communication always proceeded smoothly and professionally. I don't usually write "Google" opinions at all, let alone a glowing one like this, but I couldn't resist! KUDOS! to Dr. Leiboff and his staff and a big THANK YOU!
