Sean O’Connor was announced as the Knights’ head baseball coach on August 16, 2019. He is just the Knights’ fourth baseball head coach since 1984.
Prior to CCBC Essex, he was the head varsity coach at DeMatha Catholic High School in Hyattsville, Md. (2008-2019) During this time, he led his alma mater to over 200 wins, including two Washington Catholic Athletic Conference Championships (2008 and 2013) and six finals appearances (2010, 2011, 2015, 2017, 2018 and 2019), and three Maryland Private School Championships (2010, 2011 and 2017).
He has garnered five Coach of the Year awards from the American Baseball Coaches Association (Region II Coach of the Year, 2013 and 2019), Maryland State Coaches Association (2008 and 2013), and WCAC (2009). Prior to taking over the varsity team at DeMatha, O’Connor spent nine seasons (1999-2008) coaching the Stags’ freshman team and as an assistant varsity coach.
O’Connor has been the owner of CrabFest Baseball since 2011 and head coach since 2016, guiding the team to a fifth-place finish at the 2017,2019,2021 All-American Amateur Baseball Association (AAABA) National Championship, and second place in the National Amateur Baseball Federation (NABF) Senior Division National Championship in 2016. In his five seasons at the helm for American Legion Greenbelt Post 136 (2012-2016), his teams won the 2012 NABF Regional Championship and were the 2013 Frank Riley League Champions. As the head coach of Canes Baseball (2013-2016), O’Connor led his teams to three championships, one runner-up finish, and a finals appearance.
He attended and played baseball at DeMatha (1990-1994) before playing collegiately at Western Maryland College (now McDaniel College) until 1996 when injury cut short his career. He holds his Bachelor of Arts degree in Business Administration from Western Maryland.
O’Connor has owned and operated All in Broadcasting, a video, and audio streaming company, since 2001, and is the state director for National Identification Team Selection (USA Baseball) where he plans and implements player identification programs for the state of Maryland.
He currently resides in Silver Spring, Md.
CCBC Essex Baseball Head Coach Sean O’Connor named Tim O’Brien as the Knights’ pitching coach in August 2019. O’Brien is a former Major League Baseball associate scout for the Florida Marlins (1993-2002) and Baltimore Orioles (2004-2007).
He spent nine years (2001-2009) as a pitching coach, Junior National Program site supervisor (Florida), and Junior National Trials team coach for U.S.A. Baseball. Under his leadership, the Women’s National Team earned a bronze medal at the 2010 International Baseball Federation World Cup, and the Champion’s Program captured gold at the 2007 Pan American Games.
From 2009-2017, O’Brien was an assistant coach for the University of Maryland Baltimore County. During his time at UMBC (which also included the 1992 season), the Retrievers’ team earned run average decreased, and in 2011 no one on the pitching staff missed time to injury thanks in part to O’Brien’s tutelage and rigorous fitness program. Under his coordination, Retriever’s baseball student-athletes also supported Cardboard 2 Leather, a donation drive organized by the Baltimore Oriole Advocates that aims to collect new and slightly used baseball equipment for those in less fortunate situations around the world.
Prior to UMBC, O’Brien was the head coach and general manager of the Columbia Reds 16u baseball team (1999-2008). His teams advanced to the National Amateur Baseball Federation (NABF) World Series in 2005 and 2006, earning a finalist appearance during the latter season. In 2006, O’Brien was also an assistant coach for the Maryland Bombers of the Cal Ripken Sr. Collegiate Summer League.
O’Brien spent 16 years as a head baseball coach for Wilde Lake (1992-1993), Oakland Mills (1994-1996), and Long Reach (1997-2008) high schools. He earned numerous awards, including American Baseball Coaches Association Regional Coach of the Year (2005) and The Baltimore Sun and The Washington Post Howard County Coach of the Year (2002).
O’Brien, a former Maryland State Association of Baseball Coaches president and athletic director at The Cardinal Gibbons High School, earned his bachelor’s degree in education at Niagara University (New York) and his Master of Education in administration and supervision from Loyola College Maryland. He was an educator for over 40 years, and currently teaches American Government, Advanced Placement Government and Politics, and Leadership for Long Reach High School.
O’Brien lives with his wife, Mary Beth, in Columbia, Md. They have two sons, Robbie and Kevin, both of whom played collegiate baseball.
