How likely are you to recommend Dr. Kowalsky?

(Select your rating)
Dr. Kowalsky is a fantastic orthopedic physician. He operated on my shoulder about six months ago and did a wonderful job. He is honest even when it is hard to hear and does not waver from what is the best way to proceed . He also consults with others if there is even the smallest issue, So you always have the benefit of best and a most informed decision. Dr. Kowolsky is a gifted physician. In addition, he has time and gives it to his patients; he listens intently and is available. I recommend Dr Kowolsky without reservation to anyone who needs a shoulder repair.
