Mary Ellen Trevino, Owner, P3S Corporation, No. 17

The daughter of a Mexican immigrant mother and American father, Mary Ellen Trevino grew up in Port Isabel -- a town on the Texas-Mexico border -- under difficult financial circumstances. Her father was a stroke victim and unable to work, so Trevino studied hard in high school and earned a scholarship to attend college at St. Mary’s University. She went on to get her MBA and began a career in the federal sector. She started P3S Corporation in 2005 to provide a variety of business solutions to the federal government.
