Following are comments provided by some of Dr. Keisch’s breast brachytherapy patients:
Maria Diaz, Hialeah, FL
I thank God and Dr. Keisch every day for giving me a second chance. Dr. Keisch is marvelous, and I will follow him wherever he goes. I went to another hospital and they wanted to perform surgery, but my daughter insisted I get a second opinion. Dr. Keisch gave me radiation therapy and saved my breast. I am eternally grateful to him. May God bless him.
Debbie Arbelo, Hialeah, FL
Dr. Keisch always made me feel as if I was a partner and a participant in my medical care, not just a patient. He did the MammoSite, and everything turned out very well. Through it all, Dr. Keisch always made time to listen and answer all my questions. He was very down to earth, and he didn’t talk in terms I couldn’t understand. Just as important, he has a wonderful sense of humor, and I never left his office without a smile. It means a lot that he could make me laugh during such a difficult time in my life. His office staff members are great too, and they had a very positive impact on my life.
Jane Gross, Miami Beach, FL
The brachytherapy allowed me to be finished with treatment in one week instead of 6 weeks of daily sessions. That meant by Thanksgiving instead of New Year. It was over so fast and the holiday season was joyous to say the least. Dr. Keisch is not only a competent, cutting-edge radiologist, he is a kind and compassionate man with a great sense of humor who instills confidence and as much information as you want. He is a rare combination of medical excellence and personal warmth. I highly recommend his services.
Jose Lacera, Miami, FL
I have only good things to say about Dr. Keisch and his staff. The quality of the care is superior, and I always felt I was in the best hands. The entire team is professional, dedicated, and gives personal attention. They go out of their way to make sure that all your questions are answered and make you feel comfortable.
Gerard Attardi, Plantation, FL
Dr. Keisch saved my life. I had been going to a Urologist for a few years who kept giving me biopsies and kept telling me I was okay, and when I finally got to Dr. Keisch I found out I actually had prostate cancer, so I went ahead and did high-dose radiation with Dr. Keisch. That was more than five years ago, and I haven’t had any problems since then. I have met a lot of doctors in my years, and there are many few of them I feel I would recommend. However, I would recommend Dr. Keisch to anyone. He’s very thorough and precise, and he’s a great doctor.
Leon Srebrenik, Surfside, FL
Dr. Keisch is a great doctor. He’s very thorough, and he has very good bed-side manners. He’s very caring and compassionate with his patients. I will follow him wherever he goes.
