Dr Cosmi is spectacular. Hes got his stuff together. He is smart but also very compassionate and present. he takes his time. clearly explains what he sees is going on with you and the procedure options. I had some sort of serious stuff going on but I always felt safe with him and his NAs. Also it was really good that he was part of a group. there is always coverage and i did call twice on a weekend and received a prompt return call from the doctor on call. support staff is also super nice..

Dr. Cosmi is a breath of fresh air. When you hear his voice and see his smile, you know that you are in good hands. I have been his patient for 12 years. He saved my life. His caring, calm demeanor puts you at ease. He is so caring and loving and really cares about you! I am sure he has 100's of patients, but he always makes me feel special. Thank you Dr. Cosmi, if not for you, I would have missed being and playing with my 4 beautiful grandchildren. I am truly thankful! Joanne Loya

I had my first office visit with Dr. Cosmi today and found him to be warm, patient, and very knowledgeable. He took his time and explained my test results and the choices going forward. His office staff, from reception to the intake nurse, were also warm and friendly.

Dr. Cosmi is a wonderful doctor and extremely professional. He has done not one but two serious procedures on a family member of mine in the last 10 years. Not only is he compassionate with the patient but he shows respect to the families as well. He takes his time explaining exactly what the situation is and answers any questions. Today because of him my daughters still have a father. Thank you John Cosmi for we are truly grateful and appreciate everything you have done.
