Heather Heffernan Assistant Coach

Coach Heather began her coaching career in 1999 in North Platte, NE as an assistant coach for North Platte Swim Team.  As part of this role, she learned the ropes and handled the "dry" side of the sport with team administration duties while also assisting on the deck with the wet side.  Over the years, Coach Heather also assisted with summer-only GNST club teams in Cozad and Valentine, NE, sharing her roles with both the administrative and coaching duties.  In 2005, Coach Heather and her late husband, Archie, started the Greater Nebraska Swim Team with its first satellite locations in North Platte and Kearney.  In 2012, she took on the role of head coach for the North Platte GNST team.  In addition, she served as an assistant coach for the North Platte High School swim team from 2015-2019 and provided over 15 years of private and group lessons and clinics for hundreds of athletes in the North Platte area. During the winter of 2020, Coach Heather began her "PRN" status in helping cover all levels for GNST in Lincoln and continues in this capacity today.

With two children in college who have been involved with swimming from a very young age, she is also very familiar with the swim parent role as well.  

She first began her "career" as a stay-at-home and homeschool parent for over 14 years and has since transitioned into outside employment, working primarily in public schools and early childhood education programs. While Coach Heather is still refining her future vision and goals, she hopes it will always include sharing the sport of swimming with others.

He continued to compete with Norfolk High through his senior year, when he qualified for State in the 100 Breast and 200 IM.

While back in Lincoln, Chris began teaching stroke technique lessons with Great Plains Aquatics Club (now known as HLA), and began swimming with the Psuedo Master’s group under GPAC coach Terri Hermes. Coach Chris is excited to help other swimmers continue their love for the sport, and maybe they’ll make it a life-long passion as he has.
