Dion Mepham and Adam


They follow the club philosophy that the swimmer comes first.


Dion Mepham

Appointed Head Coach of Trinity College in 2004, Dion formed Western Sprint SC shortly after and has . He has coached extensively, across the complete spectrum of the sport, from setting up the Learn-to-swim through to coaching elite athletes on Australian teams.

Dion has coached Australia at the World University Games and Oceania Championships, as well as many youth teams. He has coached Western Australia at National Championships, State Teams, Pacific School Games and School Sport.

Having coached swimmers to over 100 National Championship medals and hundreds of State titles in the last 30 years, his experience has led to a deep mechanical understanding of movement patterns which are adopted by International water polo, lifesaving and surf athletes as well as pool swimmers.

Dion believes strongly in holistic coaching techniques that focus on elevating the wellbeing of the athlete above all else. Impeccable technical mechanics, balanced with insightful training methods, develop purposeful and engaged athletes, who excel beyond expectations.

He is convinced that engaging properly in the Western Sprint programme will not only produce a better athletic outcome but will provide the athlete with a series of life skills that last long beyond a ‘swimming career’.


Adam Koprowski


Adam is a highly regarded swim coach with a great following at Western Sprint SC. For the last  3 years, he has coached a very successful squad to State Championships, including 5 Gold medals, a great result in such a short time coaching. Adam is a fine technician and a great motivator, having been awarded the Swimming WA ‘Best Club Person’ for WA in 2020. Adam is an accomplished swimmer himself, having placed 4th at the 2019 World Masters Games in the 50m Backstroke. He is a fine role model for young swimmers.


Siobhan Wilkins

Siobhan joined the coaching team with Western Sprint in 2018 and is a former National swimmer of the club. Siobhan’s love of swimming began back as a junior where she competed at a State and National level across her swimming career. Siobhan competed at her first National back in 2007 and continued to compete at each Nationals in the years following. Siobhan won a number of state gold medals across her career in events such at the 50 Backstroke/Freestyle, 100 Backstroke/Freestyle and 200 Backstroke/ Freestyle. Siobhan has continued swimming into adulthood and now competes as a master swimmer. She recently competed in the 2018 Masters Swimming Australia National Championships where she won 6 gold medals in her age group.  

Siobhan thoroughly enjoys sharing her knowledge of swimming with Junior swimmers and this encouraged her to commence working with Western Sprint as a coach. Coaching enables Siobhan to give back to the community and work with younger swimmers to encourage them to achieve their goals and swim to the best of their ability.

Aside from her work with Western Sprint, Siobhan also coaches with the Trinity College Interschool Swim Team (and previously their Junior School Squads), and a variety of Masters Swimming Programs for adults.
