Good Morning, I had CK in Dec. at Winthrop University Hospital, Jonathan Haas, MD Dr. Haas heads up the CyberKnife Center there. He is a wonderful doctor, compassionate and most of all is available for any concerns or questions, whether on the phone or at an office visit. He runs a tight ship and all at the facility are a great group always willing to be helpful. I am post CK 6 months, with a few problems i.e. numbess, continued tinnitus (which will probably never go away) and feeling wonky most of the time. I can't seem to articulate the words that are in my head...but...the tumor is under control and eventually I will feel way better..but getting back to Dr. Haas, I highly recommend. His recommendation came from a physican at The Ear & Eye Hospital in Manhattan. Good luck and feel free to contact me for any further info. JLR
