Jonathan A Haas

Excellent Doctor and staff. Very caring treat patients with excellent care and love ????. Other patients friendly. O y

Very rude receptionist. She hung up on me after calling our policy “ridiculous”. Did not get her name but she’s very rude when calling other practices.

I am posting on behalf of my father Sal. The entire staff was excellent and very caring. Dr. Haas made the treatment process very easy and painless. I would recommend this practice to anyone.

Great bedside manner. Professional and personable. His entire staff are great.

Dr Haas is one of the finest doctors I have ever been involved with. He is thorough and caring and makes you feel as if you are a part of his family. My treatment for prostate cancer could not have gone any better. There were no side effects and no problems. It is 5 1/2 years since I was diagnosed and treated and I am cancer free. Dr Haas and his team saved my life and my feeling is that if Dr Haas says you are a candidate for CybeKnife you would be foolish to undergo any other treatment.

Most unpleasant experience

Best doctor for prostate cancer. Great bedside manners. Follows up with patients every week.

I absolutely love Dr. Haas. For a famous doctor, he is the most down to earth genuine person I have ever met. There is no ego and I have access to him anytime I want. He did cyberknife on my prostate cancer 3 years ago. I am doing great, my PSA is 0.2 and feel I am in the best of hands with Jonathan Haas. I cannot recommend him highly enough.

The diagnosis of prostate cancer is breathtakingly shocking at any age, and the options though limited are very complex and the prognosis depends on many factors. All of that said, if you are a candidate for and choose the option of Cyberknife with Dr. Hass, as I did in 2019, you will find him to be frank and honest with prognosis, but at the same time caring, thorough and with such an authentic enthusiasm that you walk out of his office feeling encouraged and not discouraged. His staff was the best and caring as well. My PSA went from 6.5 to 0.4 on my first followup and I now look forward to a positive outcome thanks to Dr. Hass and his staff.

I have seen Dr. Haas multiple times over the past few years for my prostate cancer. He is one of the most compassionate, informative, and friendly doctors I have ever encountered. He also does not push his treatment on you unneccesarily. He takes his time and explains all your concerns. I can highly recommend him.

The Best

Dr. Haas was extremely thorough and clear regarding my upcoming radiation treatment - exactly what I was looking for. He patiently answered all my questions so that by the time I began treatment I knew exactly what to expect. I met with Dr. Haas regularly during treatment - once a week - and he even fit me in when a problem arose. His staff at the treatment center are caring, friendly, and supportive, aside from being extremely professional and knowledgeable. They were an amazing support team during my treatment and I am so very grateful to Dr. Haas and his entire team for helping me get through what, as you can imagine, was a difficult time. I highly recommend them!!!!

Amazing Ihad the cyber knife in 2010. Never missed a day or work. Had mild managable side effects for about a week after. Since then I’ve been 100% and cancer free. Dr. Haas is the best.

I don't care what your review are about dr Haas md is my personal experience with him he ruined my life his radiation treatments will leave u impertinent. Avoid this guy by all means

I was dianosed with prostate cancer and after careful research, chose Dr Haas for cyber knife. He was great to work with. Very professional and caring. His team was great as well. The treatment was 5 half hour treatments mon-fri. I had no side effects other than a slight urge to urinate for a week or so. I was able to walk my daily 4 miles and I even played golf right after treatment. I just had my 3 month follow up and my psa dropped from 4.6 to 1.6 and should continue to drop. I am very happy

I came in not knowing what to think. Dr. Haas was so kind and soft spoken. He portrayed the confidence I needed to feel comfortable with the decision I made to go forward with Cyberknife vs surgery. The staff was so warm and friendly. I felt like I was there only patient.

Doctor Haas and his staff are the nicest, kindest, most professional people I have ever met. They literally saved my life with their knowledge and the use of Cyberknife. I highly recommend these medical professionals to help you, guide you and most of all treat your cancer. I spent countless hours and days researching and interviewing various medical professionals in order to determine the best course of action for me. Hands down it was Cyberknife and Dr. Haas. I am forever grateful.

I was a world class triathlete who found out in April this year that I had Prostate Cancer...Shocking and yet understandable since the # skew as you reach 70. After a few conversations with colleagues, and I was fortunate one of my business partners was a urologist by training, and understood the issue at hand. We discussed all the options, and came away with the lead horse was the Cyberknife program at Winthrop and Dr. Haas. Today I completed my 28th and last treatment under his direct supervis
