Robert "Bob" William Sines, 52, of Hagerstown, MD, passed away on Sunday, April 11th, 2021, at UM Prince George's Hospital Center. Born December 17th, 1968 in Oakland, MD, he was the son of Patsy Sines. Bob was a 1987 graduate of Boonsboro High School. He spent his life doing construction, in which he found great joy. He was a very skilled carpenter and craftsman in which he was creative both at work and home. His favorite pastime was fishing and watching western TV shows. Bob is survived by his daughter, Brittany N. Donarski, her husband Evan, and her mother Pamela Sines. In addition, his dear friend, William Cobb. He was separated from his siblings at a young age, but he remained in contact with his sister, Pam Ritchie. Bob was preceded in death by his loving pet companion, Nikitia Grace. We are confident he is finally reunited with her and at peace. Per Bob's request, no services will be held.
