Robert "Bob" M. Sontag

June 22, 1941January 9, 2021

Robert (Bobby/Bob) Michael Sontag of Dedham entered into rest at the age of 79. Beloved companion of the late Avis (Goldstein) Stiller. Loving and devoted father of Jodi O’Keefe and her partner Sean O’Leary of Foxboro and Kristi Slavin and her husband Brian of Brookline. Dear step-father of Scot Stiller and his wife Kim of Upton and Dawn Stiller of Stoughton. Cherished Papa of Kasey, Kylie and Matthew O’Keefe; Paige and Brynn Stiller; and Waylon, Easton, Nash and Harlo Slavin. Robert is also survived by close cousins Leslie and Richard Saltzberg, Stephen Freedman and partner Carol Sneider, and Karen Sontag.

Bob was a well-respected salesman working in the printing and publishing industry, but was forced to give up the career he loved due to his health. He dutifully served as President of the YMHA Alumni Association since it was founded in 1975. Most of all, Bob cherished his time with friends and family and was always there to help with whatever people needed him for. Bob loved watching sports whether it be professional or his grandkids various activities and enjoyed spending summer days at the beach. He will be dearly missed by all who knew him.

When we had our summer get together Bob was always willing to help out with the grilling. Just a great guy who would help you in any way he could.
Our thoughts go out to his family

Bob was a special human being who was always 1st to console family or friends during sickness or rough times. Nothing was more important to Bob then spending time with his family & friends. He will truly be missed.

Please accept our sincere condolences. We are very old friends from the YMHA. Most of us didn't have a lot in those days, but we had each other. Our friendships were very special. We cherish those memories. We will miss Bob. Stay strong.

Anita(Caswell) and Jay Wassersug
