Rep. Dom Costa's Biography

State Rep. Dom Costa has dedicated his life to public service.

As a child, he dreamed of being a police officer and was always prepared to protect classmates from bullies. He was greatly impacted by the stories family friend and police officer Mayer DeRoy would tell him about life in law enforcement.

Following in his father Albert's footsteps, Costa began working as a plumber following his graduation from Penn Hills High School in 1970. He taught the trade through the Mon Yough Plumbing Apprenticeship Program, received his master plumber's license, and later opened his own plumbing business. It was there he gained firsthand appreciation for the challenges and rewards small-business owners experience.

In 1977, Costa's inherent desire to protect and serve his community resurfaced. He became a part-time police officer in East McKeesport. He then joined the Pittsburgh Police Department in 1979. There, he rose through the ranks from patrolman up to commander. In February 2002, Costa retired from the police force after being shot in the line of duty.

In 2005, he was called to serve as the chief of police by late Pittsburgh Mayor Bob O'Connor. O'Connor encouraged Costa to run for public office. Mayor O'Connor passed away in 2006 and Costa followed his advice. He ran and won the state House seat for the 21st Legislative District.

Costa serves as the Allegheny County Delegation Chairman. He is a member of the House Gaming Oversight, Insurance, Judiciary, Policy and Rules committees. His legislative priorities include public safety, animal protection, education and mental health services.

Costa resides in Pittsburgh with his wife Darlene and their two West Highland White Terriers, Rocky and Max. He has three children, Tina, Julie and Scott. Tina is married to Tom Delaney, Julie is married to Devin Malcom and they have blessed Dom with two grandchildren: Quinn and Liam. Scott works in the technology field and resides in Pittsburgh.
