A Palmyra, Pa., native, Seibert has the distinction as Dean of the Green Terror staff, entering his 37th season at the helm of the Green Terror baseball program.
In 1984, Seibert coached the Green Terror to the Middle Atlantic Conference Championship. In 1989, his squad won the Southwest League championship.
In 1995, the team set a then-program record for wins in a season (19), resulting in Seibert being named Maryland’s College Coach of the Year by the Maryland State Association of Baseball Coaches.
In 2012, Seibert guided his Green Terror squad to its best year ever. The team amassed a 24-13 record for the first 20-win season in program history and returned to the Centennial Conference (CC) playoffs for the first time in 10 seasons and its first-ever postseason berth with an appearance in the ECAC South Championship.
The 2012 McDaniel squad recorded its first perfect spring training trip with an 8-0 record in Winter Haven, Fla. The end of that stretch coincided with Seibert’s 400th victory. The Green Terror added two more wins onto that streak for a program-best 10-game winning streak and later added a seven-game winning streak.
For an encore, the Green Terror made it consecutive 20-win campaigns. The squad finished 22-16 and advanced to the championship game of the ECAC South tournament.
McDaniel returned the postseason in 2015 with berths in the CC and ECAC tournaments, including advancing to the championship game as the top seed of the ECAC Southeast tournament.
In the 2016, Seibert took his squad to new heights, guiding the team to a 31-10 record. The 31 wins established a new program-best mark and was good enough to get McDaniel into the CC tournament once again, where the Green Terror captured its first tournament win.
With a 6-2 home win over Ursinus on the final day of the regular season, Seibert joined the 500-win club as head coach.
Seibert is also a member of the American Baseball Coaches Association’s “Century Club,” amassing more than 500 career wins.
Seibert’s coaching experience extends beyond the baseball diamond. For 14 seasons, he served as the defensive coordinator of the Green Terror football team. The veteran coach then oversaw the squad’s quarterbacks for four seasons, coaching two of the Centennial Conference’s best signal-callers – Brian Van Deusen and Ron Sermarini.
In 2009, Seibert produced the program’s first player to be drafted to play Major League Baseball. Harold Baines, Jr., son of former White Sox and Orioles great Harold Baines, Sr., was taking by his father’s White Sox in the 45th round and spent the summer playing for the franchise’s Advanced Rookie team in Bristol, Tenn.
Seibert is a senior coach lecturer in the Exercise Science and Physical Education department, teaching the popular course, “America’s Game: Baseball,” which is offered as a first-year seminar.
Away from the College, Seibert is the director of the Central Pennsylvania Rotary International District 7390 Youth Leadership Conference.
The 1978 Western Maryland College (now McDaniel College) graduate received his bachelor’s degree in physical education and earned his masters degree in educational administration in 1981. As an undergraduate, Seibert played on both the football and baseball teams.
