Dr. Gredysa saved my life. I had carotid artery surgery done in January of 2018 and I feel great. Lucky for me Dr. Gredysa came highly recommended, without his expertise the outcome would have been very different for sure. I thank him and his wonderful staff for being there for me every step of the way and saving my life.

Dr Gredysa and his staff were accommodating, attentive and caring. They communicated clearly and, while under their care, I felt I was getting the best possible medical care. It is, in my opinion, the way medicine should be practiced.

Dr. Leslaw Gredysa recenyly performed colorectal surgery on me to remove a tumor. My experience with him was totally positive. The speed in which everything was scheduled and performed was exceptionally fast. His staff was responsive to the urgency of the situation and extremely helpful in the scheduling process. Following the surgery, Dr. Gredysa was with me every day and careful to explain in detail what had occurred and respond to all my questions. Overall I was extremely impressed.

Dr. Gredysa performed my emergency surgery. I was impressed by his level of expertise/competence and was greatly reassured by his self confidence. All medical information was explained to us in a manner that was "patient friendly." Dealings with his office and staff were very satisfactory. I highly recommend Dr. Gredysa.

I had an unexpected emergent medical problem that required surgery. My shock, fear and concerns were immediately 110% relieved and alleviated when the nurse in the E.R. informed me that Dr. Gredysa "was on his way". Imagine knowing you were heading into surgery without one concern and total confidence? That is exactly what you will experience with Dr. Gredysa. My procedure was flawless and his communication was impeccable. Dr. Gredysa's skills as a surgeon are incomparable.
