She attended Mountain View High and lettered in swimming all four years of her high school career. Her favorite swim stroke is the butterfly- she once swam a 500-yard butterfly race because she whined too much to her coach about how long the 100 fly race was! She graduated from Brigham Young University with a bachelor’s degree in Recreation Management, emphasis in Youth Leadership.  Missy started her coaching career in 2000 and coached swim teams with Orem Timpanogos Aquatics Club, Mountain View High School, Timpanogos High School, and the City of Orem. She is very excited to be apart of the Northside Alamo Area Aquatics Association Swim Team.  She is certified through United States Swimming (USS), American Swim Coaches Association (ASCA), American Sports Education Program (ASEP), and Red Cross (first aid, CPR, and coaches’ safety).   Missy loves swimming and working with kids.
