William O'Dwyer (1936-2026)

Closed the afternoon of June 18th, 2026

With the increase in some local practices closing we have been inundated with transfer patients. In order to better serve our current patients we are at this time only accepting newborn children to the practice.

Shaker Pediatrics PC is saddened to share that one of our founding members of the practice, William A. Petersen MD has passed away. Originally known as Boland, Petersen & O'Dwyer MD's, Dr. Petersen was an integral member of the elite group of pediatricians for Latham and Loudonville. Dr. Petersen retired from the practice back in 2015 after devoting his life to caring for many of the Capital Region's children and their parents for 50 years. Always an impeccable dresser, Dr. P was known for wearing his amazing plaid pants at every staff Christmas party and his salmon Bermuda shorts to each summer party we had. Every Halloween (also his birthday) he came dressed up in his Army uniform from 1957 which always fit perfectly! He was loved by each and everyone of us, always bringing a smile to our faces with his familiar "greetings" whenever he came back to visit us after retirement. We'd like to think we were his second family but we all know he was family to everyone he knew! While we hadn't seen his face in a while at the office, we know he still thought of us often and had just recently called to say hello and that he missed those of us who still remembered him at the office. Dr. P was a true gentle man with exceptional bedside manner to each and everyone of his patients and their parents. We will miss him immensely and will continue to carry on with his practice!
