Bill McGregor, who turned DeMatha Catholic into the premier high school football program in Maryland and one of the nation’s elite, resigned Monday after 29 seasons at the Prince George’s County school.

“I am moving on to a different phase of my life and am exploring different options,” McGregor said in a statement. “DeMatha has been great to me and my family. I cannot thank the administration, faculty, staff, and DeMatha family enough for all of the support throughout the years. … The DeMatha players made DeMatha what it is today. DeMatha was a great place before I got here; it will be a great place after I leave.”

The Washington Post reported Monday McGregor will join Gilman School coach Biff Poggi in a business venture. Poggi and McGregor are longtime friends as well as rivals as the two private powerhouses have met yearly since 2000.

An attempt to reach Poggi was unsuccessful.  

McGregor went 280-39-3 in 29 seasons with 18 Washington Catholic Athletic Conference championships, including six straight from 2003-2008. His teams finished No. 1 in the Washington metro area eight times and the statewide media football poll a record five times.

More than 350 of McGregor’s players received a college scholarship and he’s been credited by several coaches for getting their players scholarships. Five former Stags are currently in the NFL including Baltimore Ravens safety Josh Wilson.

McGregor was named NFL’s High School Coach of the Year in 2004.
