Coaching Staff

Brent Moore

Head Coach


   Hello, my name is Brent Moore I’m very excited about being the head coach for the Sheridan Swim Team. I grew up swimming in Fort Collins, CO. I swam for our neighborhood summer club team, and for Rocky Mtn. High School where I still hold a record with my 200 free relay team. I began coaching during my high school career in 1992 and have continued ever since. I attended Whittier College in CA where I played water polo and swam. While there I earned all conference water polo honors and formerly held school records in the 100 and 200 freestyle. I also earned a BA degree in exercise science. While in California I began coaching at the high school level while continuing to coach summer club teams in Fort Collins over the summers, eventually moving into coaching year round. I have coached all levels of swimmers in my time with various teams ranging from summer league to high school, masters to year round teams; with athletes ranging from beginners to adults, 8 & unders and All-Americans. Most recently I have come from Poudre High School, where I had been the head coach for 12 years. While at Poudre I had been named Front Range League Coach of the year 7 times, coached state champions, and placed consistently in the top 10 state team standings. Somewhere along the way I managed to complete a master’s degree in education administration, marry the love of my life, and begin to raise my own children. I’m very excited about the possibilities here in Sheridan. I’m looking forward to getting to know each athlete, creating a very positive team atmosphere, and developing great swimmers with outstanding character. I hope to give swimmers sound stroke technique work balanced with aerobic training to help them reach their goals in the pool. I believe first and foremost in personal improvement and becoming the best you can be. With that as the primary goal having fun and winning will eventually come.

Avery Karns

Assistant Coach


Hello my name is Avery Karns and I am thrilled to be a new Assistant Coach for the Sheridan Swim Team as of Summer 2017. I started taking summer swim lessons when I was about 7-8 years old at the closest pool my country childhood home 30 minutes away. Around 10 years old my parents and I decided this was something I loved so much it was worth some real training. So I began swimming for Longhorn Aquatics at the University of Texas at Austin. I had the great priviledge of working with some of the top coaches and athletes the sport had to offer at the time. Whitney Hedgepeth and occasional 4-Time Olympian Jill Sterkel were among  I had to work really hard to catch up since most kids around me had been training at the year round level since 7 or 8 years old. I was determined to show everyone that even if you started "late" you could still catch up and maybe even take the lead sometimes! By the time I was 13 years old I was swimming on the National level team at Longhorn Aquatics. I later switched to the Circle C Ranch Swim Team under the coaching of Randy Reese a former U.S. Olympic Coach. It was with Randy that I learned a lot more about swimming itself. I learned about how to stroke clinic, structure work out sets for specific results from swimmers, and taper (prepare for an upcoming swim meet). While at Circle C Ranch I also had the privilege of swimming alongside, watching and learning from Olympic swimmers like Josh Davis, Ron Karnaugh, Jeremy Knowles of the Bahamas, Sandy Neilsen-Bell, and many more.
In 2003 my senior year of high school I joined my high school swim team along with a few of my fellow Circle C swimmers and together we won the first State Championship in our schools history. It was then we set State records for the 400M Freestyle relay and 400M Individual Medley relay of a 5A high school.
While attending Texas A&M University I chose to mix it up and try out Water Polo for the first time. I joined the team, played hard, and enjoyed a truly rewarding 2 years with a great team of people. It was in water polo that I came to appreciate even more the importance of a cohesive and well bonded team.
After completing my B.S. in Biomedical Science at Texas A&M in 2003 I headed off to Parker University in Dallas,TX to pursue and Doctor of Chiropractic degree. It was at Parker that I met the man of my dreams, Tyler Karns. At the time he was the captain/coach of our intermural swim team at Parker as well as current Chiropractic student. I was able to become a great asset to the team and eventually began coaching. Our team won 3 consecutive "International" Championships among our American and Canadian Chiropractic Schools. I completed my Doctor of Chiropractic in 2007 and am currently licensed to practice Chiropractic in Wyoming. Tyler and I were married in 2009 and began our family soon after. We moved to Michigan to be close to family and work. I practiced Chiropractic for 3 years and Coached the Grand Rapids Community College Masters there while Tyler was a professor of Anatomy and Physiology. Eventually we moved to back to Texas and then to our forever home Sheridan, Wyoming in 2014. Our kiddos are Sebastian, Malachi, and Evangeline. You will surely see them around the pool from time to time and maybe in the pool as part of the team one day!
Now I take all the experiences from the water sports I love and channel them into effective and fun training for all my swimmers. I am so blessed to get to coach our Sheridan Swim Team, GO SHARKS GO!

Adam Martin

Assistant Coach


Hey everyone! I'm Adam Martin and I'm glad to be able to coach for the Sheridan Swim Team.  I began my swimming career in high school where I was a state finalist in Wyoming in 2009 and a club swimmer for the Casper swim Club for 2 years.  I continued swimming at Colorado Mesa University and helped my team win their first ever Rocky Mountain Athletic Conference championship in 2014.  Today I am also ranked in the all-time top 20 in 6 events for CMU and I played for their water polo club for 3 years.  My coaching career began in 2010 as a volunteer coach for record-breaking athletes at the high school level as I fell in love with sharing our sport with others.  I have worked with swimmers of all age groups, from teaching pre-school swim lessons to coaching triathletes in their 70's.  This year I decided to continue my career in Sheridan because I enjoy this town and this area.  As your coach I hope to help every athlete achieve their max potential and have fun in doing so!  We will be making memories here in SST that will last a lifetime.
