Bethany has always been a lover of water, spending every waking hour possible in the rivers and lakes around her home town of Forest Grove. She decided to try the High School Swim Team her freshman year and ended up falling in love with competitive swimming (butterfly and backstroke were her favorite strokes), followed by joining the High School Water polo Team as their goalie. She competed and lettered in both sports throughout her years at Forest Grove High School and continued to swim and play Water polo at Western Oregon University.  


While taking a weight lifting class in college, Bethany realized she wanted to learn everything about health, fitness, and coaching. She helped coach and train the Western Oregon University Women's and Co-Ed Water polo teams before receiving a Bachelors Degree in Health and Physical Education from Western Oregon University in 2004. After graduating, Bethany proceeded to get certified for Personal Training, Water Aerobics, and Pilates, teaching in multiple local gyms and private sessions. Shortly after, she and her husband decided it was time to start a family and she's been waiting ever since to start up the coaching career she dreamed about since college!
