Jonathan Haas, MD

I saw Dr. Haas for a prostate cancer consult and he was light years ahead of the other oncologists and surgeons I met. He went through all options, gave me a chance to ask all my questions and actually gave me answers to many questions I didn’t ask. I never felt rushed even though he is famous and my wife and I fell in love with him. He also has a really nice nurse named Brian who works with him and has been following up with us as well. We are having cyberknife with him shortly. Great doctor and we are lucky to have him as my doctor.

My title says it all

I had Cyberknife with Dr. Jon Haas and I am very happy. He is professional, responsive, and the experience was good given the fact that I had to be treated. I had Gleason 7 so I couldn’t watch it. I was glad I chose him and the Winthrop team.

Dr. Haas is just a wonderful man. I recently had my 5 year anniversary of him curing me of my prostate cancer. He offered to let me"graduate" from him. I said absolutely not. My wife and I look forward to seeing him yearly at this point. We know everything about him and his family and we absolutely love him. A mensch!

After being diagnosed with prostate cancer I decided to see Dr. Haas about Cyber Knife radiation treatment. This was one of the best decisions I have ever made. He guided me through the entire process and was very caring. The entire staff at Winthrop was incredible. I had no side effects and it only took 5 days. I highly recommend Dr. Haas and Winthrop.

I had seen Dr. Haas over the two years of my prostate cancer considering radiation, but instead chose surgery. Despite this his consultations and advice were stellar, kind and very informative. The fact that I decided to stay with my original practice had no impact on his sage counsel. I highly recommend him! Great guy!

I have seen Dr. Haas over the past few years. He is one of the most compassionate doctors I have ever seen. He explains things in great detail, without pushing his treatment on you. I feel like I'm in the best of hands with him. its easy to make and appointment and the office is modern and well staffed. I can highly recommend him!

I used Dr. Jonathan Haas for my prostate cancer treatment. He was really great. I had a cyberknife with him 3 years ago. My PSA is 0.3, I had no side effects and see him twice a year now for follow up. I've called him a few times with questions and he always returns my calls. Several of my friends from my community also have used him and are also very happy.

I wish I could give 10 stars instead of 5 stars. Dr. Haas is incredible. He treated me for my throat cancer 8 years ago with regular radiation and my prostate cancer more recently with the Cyber Knife. Both cancers are gone. He hasn't aged in between and I owe him everything!

Love my Dr. Johnny!!
