Frank J. Mammano, 84, passed away peacefully at his home in Forestville, MD on Saturday, June 4, 2022. Born on April 27, 1938 in Washington, DC to the late Rose and Joseph Mammano, Frank graduated from Holy Name Elementary School and from Gonzaga High School in 1956. After graduation he enlisted in the Army Reserves, where he served a total of 8 years. Frank earned a Bachelors of Science degree in Electrical Engineering from Catholic University and after graduating in 1960, he married the love of his life, Judy Rohan.  Judy and Frank resided in Forestville, MD, where they raised their eight children.  While raising his family, Frank also earned a Master of Science Degree in Civil Engineering from Catholic University in 1969. He retired from the Federal Highway Administration in 1996. During his career working in the Research and Development for FHA, he was part of a team of engineers that received a patent for the subcarrier communication system. Frank was an active parishioner at Mt. Calvary Catholic Church and School for many years. He served as Athletic Director, ran spaghetti dinners with many Mt. Calvary families, parish councilman, lecturer and Eucharist minister, to name a few. He could always be seen up on the altar helping. Frank truly loved doing whatever needed to be done at Mt. Calvary. Frank had a passion for sports and believed kids should have access to a well run athletic program.  You could find Frank coaching his sons and grandchildren in baseball, officiating WCAC football games or golfing with his friends.  He became more involved at Bishop McNamara High School, after Judy passed away. Frank took up coaching the Bishop McNamara’s Girls Softball Team with his daughter, Angelina, for ten years. He was the #1 fan for the men’s and women’s basketball programs. He had his own parking space, provided by the booster club, and his own chair (with the tennis balls on the bottom) in the gym. The chair was strategically placed for Frank to high five each player as they exited and returned to the locker room. He was also known to give a little advice as well.  All coaches, athletic trainers, players, and even the spectators were supplied with fruit snacks and Rice Krispie treats. If his clothing did not have the BMHS logo on it, he didn’t wear it. Frank was preceded in death by his wife, Judy; his sons, Michael and Anthony Mammano; his parents, Joseph and Rose Mammano; his father and mother in law, Arthur and Mary Rohan; his brothers in law, Larry and Charles Rohan and his sister in law, Roseann Rohan He is survived by his children, Rose (Jeff) Ayres, Angelina (Charles) Diehlmann, Joseph (Beth), Vincent (Nancy), Frank (Laura) and Nicholas (Cindy) Mammano; his daughter in law, Sandra Mammano; his sister, Frances (Leo) McConnell; his grandchildren: Brian (Rachel), Lisa Ayres, Stephanie (Kevin) McKeown, Mark (Mary) Ayres, Anthony, Jeremy, Ryan Diehlmann, Michael (Tiffany) Mammano, Marie (Cody) Wylie, Gabriella, Joseph, Isabelle and Lucas Mammano, Victoria (Chris) Salzano, Celena (Tim) Wineand, Anthony, Jr., Frank (Sarah), Dominic, Sydney, Sophia, Giovanni, Jared and Samantha Mammano; his four great grandchildren, Lucy, Henry, Chloe, William; his brothers in law, Lex (Kathy), James (Cece), John (Mary), Franny and Tom (Jeryl) and his sisters in law, JoAnna and Marilyn.
