Brittany Stankowski Senior Group Coach
Ben Cotton Senior Group Coach
Reagan Lucas Age Group Coach
Kyle Poland Age Group Coach

I have lived in Springboro for over 10 years now with my wife, Stephanie, and two children, both current Coffman swimmers.  I grew up in Danville, Kentucky where I was an all-state cross-country runner and sprint freestyle swimmer.  I continued running and swimming collegiately at Centre College where I was fortunate to set school records in the 50 and 100yd Freestyle events.  After graduating with a bachelor degree in Psychology I moved to Ohio and began racing all distances of triathlon, running half and full marathons, and competing in road cycling events.  I won my age-group at the USA Triathlon Long-course National Age-group Championship, completed 3 full Ironman distance races, and worked up to racing at the professional level.  During this time I was also a USA Triathlon Level-2 certified coach, and head swim coach for Waynesville High School.  Triathlons led me to my current hobby of open water “marathon swimming”.  The complete opposite end of the swimming spectrum from sprinting, marathon swimming encompasses anything longer than a 10k.  My favorite marathon swims so far have been completing a swim across the English Channel in 2013 and swimming the full 27 miles around Manhattan Island in 2017.  To say swimming has been a big part of my entire life is an understatement, and I look forward to being on deck coaching for the next few years, along with continuing to do some in-water training.  I will be helping Coach Reagan and Coach Danielle with the White Group at Coffman this season.
