David Michael Trembley (born October 31, 1951 in Carthage, New York) is a former manager of the Baltimore Orioles. Before managing the Orioles Trembley was a minor league manager for twenty seasons compiling a 1369–1413 record. He won two league titles and earned Manager of the Year awards in three leagues. In December 2001, Baseball America selected him as one of minor league baseball's top five managers of the previous 20 years. He served as a coach in the inaugural Futures Game in 1999 and also served as manager for the Southern League and Double-A All-Star Games that season. Trembley worked in the Baltimore Orioles, Chicago Cubs, Pittsburgh Pirates and San Diego Padres farm systems.
Trembley is one of the rare figures in Major League history who have ascended to the position of big league manager without ever having played professional baseball at any level. Only eight such managers have ever achieved that distinction.
High school and minors
He began his career in professional baseball as a Los Angeles-area scout for the Chicago Cubs in 1984. The next season, he became an instructor in the Cubs minor league system until June, when he was named to coach at their Wytheville club in the Appalachian League.
Trembley left the Cubs organization to embark on his managing career with the unaffiliated Kinston Eagles franchise of the Class A Carolina League in 1986. It began a stretch in which he would manage in the minors in 20 of the ensuing 21 years (the lone exception being the 1990 season.) 
He joined the Pirates organization in 1987, and skippered their AA Harrisburg Senators of the Eastern League for three seasons, capturing an EL title and being named the loop's Manager of the Year. In 1990 he served as Director of the day-to-day operation of Pittsburgh's minor league complex and spring training facility at Bradenton, Florida.
Trembley was hired by the San Diego Padres in 1991, and managed their Class A South Atlantic League affiliate Charleston (SC) Rainbows in 1991 and 1992. He spent the 1993 season guiding the AA Wichita Wranglers before rejoining the Cubs organization, where he managed nine years (1994–2002) at three different levels. Trembley earned his second league title and Manager of the Year honor in 1995 when he led Class A Daytona to the Florida State League title, and also was named Manager of the Year in the Southern League in 1999 after guiding the Class AA West Tenn Diamond Jaxx to first place finishes in each half of the split-season.
Trembley joined the Orioles organization at AA Bowie in 2003. In his first season with the Baysox, he was named winner of the organization's Cal Ripken, Sr. Player Development Award. In two years at Bowie, his teams went 142–141. Trembley managed the Orioles' AAA team at Ottawa in 2005 and 2006 combining to go 143–144. 
He was promoted to Baltimore when he was named its bullpen coach on February 14, 2007. He succeeded Rick Dempsey who joined the Mid-Atlantic Sports Network as the primary studio analyst for Orioles game telecasts.
In addition to his tenure in organized Minor League Baseball, Trembley also managed one winter at Navajoa in the Mexican Pacific League, and coached third base for two years for Magallanes in the Venezuelan Winter League.
Trembley was named interim manager of the Orioles following Sam Perlozzo's dismissal on June 18, 2007. He inherited a 29–40 ballclub that was mired in last place in the American League (AL) East and in the midst of an eight-game losing streak. As a result of a 29–25 stretch, he had the interim tag removed from his title as his contract was extended through the 2008 season on August 22. Later that same night, the Orioles began a nine-game losing streak by surrendering the most runs in AL history in a 30–3 defeat to the Texas Rangers in the first game of a twi-night doubleheader at Camden Yards. The team avoided the AL East cellar despite losing 28 of its last 39 contests.
The Orioles exercised their option on Trembley's contract through the 2009 season on September 5, 2008, even though they were in last place at 63–76. They finished at the bottom of the division this time by dropping 17 of its final 22 games, including ten in a row. His contract was similarly extended again a year later on October 2, 2009 despite another last-place finish, a worse record and a 24–50 performance after the All-Star break. The moves were made because the team was in a rebuilding phase, and it was hoped that his emphasis on fundamentals would help the development of its young players.
With the Orioles still stuck in the AL East basement with a major-league-worst 15–39 record and an eight-game losing streak, Trembley was fired on June 4, 2010 and replaced by third-base coach Juan Samuel. The ballclub's 2–16 start was the second worst in franchise history. They were also stricken by a rash of injuries and the lowest run production in the majors a third into the campaign. Trembley had become a target for increasing criticism from fans who felt his disciplinary approach was too soft and that he mishandled the bullpen. Details of the latter included overworking his relief pitchers and putting them in situations to fail. His tenure lasted just under three years with a 187–283 record. His .398 win percentage was the second-lowest in club history behind Jimmy Dykes' .351 mark in 1954, the franchise's first season in Baltimore.

Trembley has a bachelor's degree in physical education and a master's degree in education, both from the State University of New York at Brockport. He also did graduate work in sports psychology at Penn State. In the off season, Trembley, his wife, Patti, and their son, Kevin, live in Daytona Beach Shores, Florida. His son Kevin is teammates with John Sgromolo, Andrew Brodbeck, Tyler Vanover and Cade Smith at Flagler College, Division 2 baseball in the Peach Belt Conference.
