Matthew Patrick O'Brien, Sr., age 58, of Collegeville, PA passed away peacefully on Monday, January 2, 2023, surrounded by his loving family. 

Matthew, the beloved son of the late Robert F.X. and Barbara (Mulford) O'Brien was born in West Chester, PA on February 23, 1964. He honorably served in the U.S. Army from 1982 to 1986, received his undergraduate degree from West Chester University in 1989, and graduate degree from Widener University in 1995. He was proud to be an Associate Director at Marinus Pharma.  

Everyone who met Matt agreed he was one of the best people they had the pleasure to know. He was selfless, supportive, affable, brave, kind, always a supporter of “the little guy” and encouraged his children to “do good things” and “not let the man bring them down.” He was passionate about researching his family history and loved caring for the family dogs Bowie, Porter, and Lacy. 

Matt is survived by his wife, Lea (née Worthington); daughters, Hannah and Emily; son, Matthew Patrick, Jr.; sisters, Marianne White, and Maureen O'Brien (James Black); brother, Christopher (Pamela Eitzen); and many beloved nieces, nephews, cousins, aunts, and uncles. 

He was preceded in death by his two brothers, Robert F.X. Jr. and Thomas J. O'Brien.
