Patient Comments (6)
in Norwalk, CT |
Most incredible person I ever met. His compassion for his work and his patients is overwhelming. He is on a mission to save lives and eradicate breast cancer. Couldn't be in better hands. Thank you Dr. Rich Zelkowitz.
in Wilton, CT |
I would highly recommend this doctor to any and all needing his expertise. It is his internal law to make sure no stone is neglected or left unturned regarding your health factors ever, period. If you fail to keep any detail of protocol current, he will personally find you and will fight for you to be diligent in monitoring your own health.

You could go on and on about how wonderful Dr. Zelkowitz is. To put it simply he is just the best doctor around as well as a caring, kind human being.
in Westport, CT |
Dr. ZELKOWITZ is an incredible oncologist. Not only is he extremely knowledgeable and thoughtful about medical issues he is also incredibly caring and accessible to his patients. I could not recommend a physician more highly.
in Milford, CT |
I had cancer. I was terrified, felt alone and confused. Dr. Zelkowitz reassured me that I would be fine, explained every step of the way, put me in the hands of a terrific surgeon, and I felt he saw me as an individual. Whenever I had an appointment he would stick his head in the waiting room and apologize for being late, even if it was just 5 minutes late. He felt my time was just as important as his. Follow-up care has been just as thorough and caring as my first. Dr Z is great!

Dr. Z as I call him is the most caring doctor I've ever known. He takes a personal interest in all of his patients. He is extremely dedicated to his work. I have no idea when he rests. You will never wait for test results as he will inform you of your results the moment they are complete. Eleven years after my treatment for stage II breast cancer he is still just as warm and caring as he was the first time I met him.
