Claire Mills Assistant Senior Coach

Coach Claire grew up in and around the Denver, Colorado area. She is in her second year with the Bolles School Sharks and has been coaching for over 6 years. She received her Bachelor's degree from the University of Northern Colorado in Sport and Exercise Science with minors in Coaching and Psychology, and is expected to complete her Master's degree in Kinesiological Sciences from Jacksonville University this April.

Prior to her arrival in Jacksonville, Coach Claire was an Associate Head Coach and Assistant Aquatics Director for the Colorado Athletic Club Stingrays in Englewood, CO. While she worked with all ages with the Stingrays, her primary focus was their Senior team. During her time with the Stingrays, she coached athletes to win CHSAA State titles, Sectional and Zone titles, and helped athletes achieve Junior National qualifying times. Several of her athletes have gone on to DI, DII, DIII, and NAIA collegiate programs. 

Coach Claire was a distance swimmer throughout her time at the University of Colorado and was a member of their Conference team for all three years that she attended. She has wanted to be a professional coach since she was 15 years old and she is excited to be able to continue her coaching journey with the Bolles School Sharks!

Outside of the pool, Coach Claire likes to spend time at the beach, go for an occasional swim, and foster dogs and cats for a local animal rescue. 

Ryan Mallam Lead Senior Coach

Coach Ryan joins the Bolles staff after coaching as an age group coach in Georgia, a Division II coach at Limestone College, the Assistant and Head coach at Indian River State College here in Florida, then Texas A&M University and Arizona State University. 

He is moving here from Atlanta where he has spent time with his family’s business and is eager to get on deck and in his words “help kids go fast.” 

Throughout the interview process it is apparent that Coach Ryan not only carries great technical expertise but cares deeply about the student-athlete as a whole person and developing the mental skills to be successful in the pool and beyond.
