From there, Mark went on to become the Head Coach at Truman State University. While at Truman, the women’s team won two NCAA Division II National Championships. His peers recognized his extraordinary contributions by awarding him the National Coach of the Year -- twice. He coached four individual (two national records) and three relay National Championship performances. Both the men and women had numerous NCAA Division II All-American performances in the pool and in the classroom.

After Truman, Mark became the Head Coach at William Jewell College in Liberty, MO. Mark had the task of starting the swim team from scratch. Mark built the program from the ground up and succeeded by consistently carrying strong roster size and sending swimmers to the NCAA Division II National Championships for the past four seasons. His men’s and women’s teams have been named College Swimming Coaches Association of American Scholars on multiple occassions. In addition, his teams won the Sportsmanship Award in the Great Lakes Valley Conference for five straight seasons for the men and four straight seasons for the women.

Mark brings great experience and results, a strong passion for swimming, strong communication skills, and exceptional stroke technique knowledge. We are confident that his strong character and commitment will ensure a fun, exciting, high-performing, and safe environment. Additionally, Mark will also serve as a coach for Bentonville High School.

Early in our process it was clear that Mark’s interest in our program was sincere. As he expressed in his cover letter, “I am extremely passionate about the sport of swimming and do my best to share that passion with every swimmer that I work with [at NWAA].”

Mark is married to Emily and they have two children, Emma (age 6) and Mason (age 4). He is looking forward to getting started soon. We are working on a time for our families to meet Mark and get to know him in person.

In 1990 she moved to Evanston, Wyoming where she was lucky enough to be involved in middle school and high school swimming as well as her club, Red Devil Aquatic Team. Her senior year she co-captained a team that placed 3rd at 4A State Championships. This has remained the highest placing for Evanston High School since moving to 4A in 1987.

Tonya began teaching swimming when she was 15 for the Swim America program that her club started. When her family moved to Bentonville, AR in 1996 she began teaching swimming lessons and swimming on the Masters team at the Walton Life Fitness Center (WLFC). This led to a brief coaching job with the Walmart Swim Club (soon to be re-named Northwest Arkansas Aquatics).

Tonya attended the University of Canberra (Australia) 2002-2004 and coached with the Capitol Belconnen Swim Club.
