“As a radiation oncologist, I approach each patient as a whole person rather than just their diagnosis. There is so much to be learned from each patient as an individual – their goals, motivations, emotions, family, and support systems – that, in addition to the technical side of medicine, lead us to the greatest likelihood of success.”

Dr. Kerwin is a consummate professional. He explains medical conditions and important test results in a relaxed and readily understandable manner. He takes his time and answers all questions thoroughly.It's evident he values developing a rapport with a patient moreso than some in the medical profession today. Most important to me, he instills confidence, trust and optimism with his engaged approach.

Dr. Kerwin is great.I went there for prostate cancer to get radiation. He read the scans and found two other cancers that I have that no other doctors found on the scan. He called it opening up pandoras box.He got a team of doctors together that are the best oncologist and ENT surgeon. After several procedures, he last PET scan wasgreat and I have a good and new outlook on life. THANK YOU Dr Kerwin

I had two prostate derived cancer tumors on my pelvis. Dr. Kerwin and his physician assistant were very patient and polite with my questions relating to the situation, and the concerns that I had regarding the radiation treatment that I received. His responses were thorough and presented in a manner that I could easily understand. I did not feel rushed in our meetings and he took the necessary time to explain the procedure and intended outcome. Both he and his assistant were empathetic to my plight. The medical staff in the radiation room were very courteous and acted professional at all times during my radiation sessions. I had a very positive experience in his care during this stressful period, and fortunately, a positive outcome occurred from the treatment I received.

Very nice, kind doctor and staff. He explained what my husband’s treatment will be, what it will accomplish, and what he can expect. He showed us the X-rays to see where the cancer is, too, which was also helpful.
