Craig Parthemer

Craig Parthemer is returning to lead the Bellevue High School Baseball program with strong local roots as a player, parent, and coach at the high school, select, and collegiate levels. Through it all, he believes firmly that together, a team can have fun, work hard, and win.

Craig was the Head Coach at Sammamish HS in 2004 and 2005.  The Totems earned KingCo playoff berths during both years.  In 2004, he coached Sammamish to an 11-7 record and third place finish in KingCo 3A after the team had won only three games the prior year.  He was selected the Seattle Post-Intelligencer (now merged with Seattle Times) Puget Sound Area Baseball Coach of the Year in 2004.  He resigned from Sammamish in 2005 to concentrate more efforts towards following the progress of his son T.J., who was entering high school ranks as a premier player in the state.

Following TJ’s local playing journey, Craig began coaching high school again in 2009 as Varsity Assistant Coach at Eastside Catholic HS through the 2010 season.  He then moved to Mount Si HS as a Varsity Assistant Coach from 2011 to 2013.  In 2011, he helped coach Mount Si to the 2011 Washington State 3A Baseball State Championship for Head Coach Elliott Cribby, now Assistant Head Coach/Pitching Coach at University of Washington. Mount Si also won three straight KingCo 3A Tournament Championships, reached the regional finals in 2012, and a fourth place finish at State in 2013. Parthemer was also a Varsity Assistant Coach at Bellevue HS in 2014. The team won the KingCo 3A regular season title. His local east-side journeys then took him to the position of Varsity Assistant Coach at Interlake HS 2015 and 2016.  The Saints qualified for KingCo 3A Tournament in 2016. Craig then took an assistant coaching position at Bellevue College from 2017-2018.


Craig is well established in the youth summer ball circuit, starting as the Head Coach of the Boys of Summer program (sponsored by Poulsbo RV) from 1999 to 2004.  Team changed sponsors to become Baden Baseball Club in 2005.  He was an assistant with Baden 2005 and 2006.  He returned again in 2010 with Boys of Summer.  He was an Assistant Coach with 18U in 2010, 2011, 2012, 2013, and 2016, and was Head Coach at 15U in 2014, and 16U in 2015. He has been an Assistant Coach for 18U since 2016.



Parthemer has helped coach five current or former Major League players, 27 MLB drafted players, and over 96 Division I players. Most notable famous players are retired Major Leaguers and World Series Winners Tim Lincecum of the San Francisco Giants and Jason Hammel of the Chicago Cubs. Parthemer’s extensive experience with high level players and longevity have made him an excellent resource for helping hundreds of players move on to college baseball.

Craig was a former All-KingCo football and baseball player at Sammamish HS.  He was Team Captain in baseball, and won the Blocker/Tackler award in football.  He was nominated for the National Football Foundation Scholar/Athlete award.  His summer ball days were spent under the legendary Coach Bob Albo (member of the state coaches’ hall of fame) with Memorex Legion.  He played baseball at the University of Washington from 1980-82.  The Huskies won Northern Division of the PAC-10 in 1981.  He played three years of Semi-Pro Baseball in Western International League 1980-82, playing for the league Champion Cheney Studs in 1982.

Parthemer has been married for 39 years to wife Joni, who runs her own small business.  His son T.J. (32) lives and works in Santa Monica, CA, and is married.  He is a former Bellevue College player (2009-10) who transferred to Cornell University.  TJ played on the 2012 Ivy League championship baseball team at Cornell and pitched in the 2012 NCAA Tournament at the regionals in Chapel Hill, NC.  His daughter Shelby (26) is a Certified Athletic Trainer after receiving her undergrad at UW and Master’s at the University of Arkansas.

Craig has been an Insurance agent for 37 years and currently co-owns a brokerage firm.
