In May 1999, the Big Beaver Falls Area School District took a risk by hiring a 28-year-old assistant coach away from rival Aliquippa High School.

While as an assistant coach to both James Deep Sr. and Mike Zmijanac, Doug Biega was part of two WPIAL (1994, 1997) and 2 PIAA (1994, 1998) Championship Aliquippa High basketball teams.

The two seasons prior to his taking over the reins for the once proud Beaver Falls basketball program, the Tigers won 1 and 3 games, respectively. Coach Doug Biega quickly returned the program to its rightful place atop the state of Pennsylvania. Coach Biega has won 78% of the games in which he has coached, winning 372 games against only 107 losses in 17 seasons. His teams have won 11 section titles. Beaver Falls Basketball under his leadership has captured four WPIAL Championships: 2005, 2012, 2013, and the latest in 2016 where the Tigers voluntarily moved up in class to AAA, despite AA enrollment. The Tigers have also been WPIAL Runners-up (2002, 2004, 2008, 2015), have won two PIAA Championships (2005, 2013), and have been PIAA Runners-up twice (2006, 2012). The Tigers under Coach Biega have won 179 out of 193 section contests (93%) and own a career playoff record of 74 wins versus 24 losses (76%).

Doug has been voted Pennsylvania Coach of the Year by the Associated Press in 2005 and 2013. The Pittsburgh Tribune Review (2005), the Pittsburgh Basketball Club (2012), and the Pittsburgh Post-Gazette (2012) have also named him their Coach of the Year.

Doug coached in perhaps the most memorable game in the history of Pennsylvania high school basketball, where his Beaver Falls Tigers won the 2005 AA WPIAL title in a three-overtime thriller against rival Aliquippa High School 79-78 in front of an overflow crowd in the AJ Polumbo Center.

Known for his defensive coaching style, his 2012 and 2013 AA WPIAL Championship game winning efforts were record setting defensively, as the Tigers held #1 seeded Monessen to 27 points in 2012 and Burrell to 33 points in 2013. In the 2016 AAA Championship, Doug's Tigers held Highlands 29 points below its 74 ppg average in a 56-45 victory.

Doug Biega graduated in 1993 from The Pennsylvania State University as an Elementary Education major. He and his wife Cary have been blessed with over 11 years of marriage and have a six-year-old son, Jack Douglas Biega.
