MESA Coaches & Board

MESA Swim Team employs a team of professional coaches. They are the only paid positions on the team. The coaches put in a lot of work during the season, and the Head Coaches help out with planning in the off-season. Most of the staff is comprised of MESA Swim Team alumni – so not only do they have the skills and enthusiasm to coach our Pirates, they also carry the spirit of the team!

If you have a question about practices, training, events, meets, goal setting, and other swimming questions, contact your Coach.

For questions about the team, such as registration, dues, safety, or policy issues, please contact one of the Board Members.

Coaching Staff

Lauren Sampl

Head Coach


Lauren has been around the pool her whole life, swimming on summer league and club teams in Fort Collins, at Fort Collins High School, and then with the University of Colorado club team. She graduated from CU in 2010 with a degree in Integrative Physiology and is a licensed massage therapist and personal trainer in addition to coaching! She has coached Mesa Swim Team since 2011 and the Colorado School of Mines since 2014, and previously coached the Fairview High School boys team and RallySport club team. Lauren loves Mesa and is thrilled to be back for another ASEM summer!   

Laurie Johnson

Assistant Coach


Laurie has been swimming competitively since she was seven. Unfortunately, her parents did not know about Mesa or BVSSL, so she instead swam with CARA until going year-round with the then Boulder Poseidon’s at the age of 12.  She swam at Fairview High School and then Cornell College.

Laurie began coaching as an assistant for Boulder Burst, when the City of Boulder started a team that was a part of BVSSL. She became the head coach after one season.  After graduation from Cornell, she continued to coach Burst in the summer, and began coaching Boys’ and Girls’ swimming at Green Mountain High School, while also working a full time position in Healthcare.  Laurie received a job opportunity in Healthcare she could not pass up, so she moved with her husband, Rob, to Lexington, Kentucky. While in Kentucky she also coached with Wildcat Aquatics, a year round club team.

In May of 2001 they moved back to Colorado and Laurie started coaching that summer with Mesa. After her second season with Mesa, about 10 days after finals in 2002, Laurie had her son, Avery. She stayed with Mesa through the summer of 2005, and then took the next two summers off (2006-2007) from coaching after her daughter, Lainey, was born.

Her love of swimming and Mesa brought her back to the team in 2008.  Laurie loves being a part of the Mesa program. In her day job, Laurie is the Director of Patient Financial Services at Estes Park Medical Center.  To maintain balance in her family and work life, she does not manage an age group, instead assisting the age group coaches with practices, line-ups, new family orientation or wherever she is needed.

She also swam for Fairview High School and the club team at Northwestern University, where she graduated with a B.S. in Journalism and a B.A. in Psychology. Jenny recently moved back to Boulder after stints in Chicago and New York City, and can't wait to meet and work with the awesome Mesa swimmers this summer!
