Lesley Serediak

Performance Coach


This is Lesley’s seventh year coaching with the Olympian Swim Club but not her first time spent with the club. As a competitive swimmer, Lesley swam eight years with the Olympians and qualified for senior nationals in the freestyle and 200 butterfly events.

Lesley’s coaching career began with the Bonnie Doon Blue Fins and although she worked with all the age groups, she found a good fit with the younger swimmers and decided to focus her efforts there. After an absence from the pool to start on her own family, Lesley returned to coaching at the Keyano Swim Club. Her extensive work with that club had her working with all age groups right up to seniors national swimmers, but it was in the development of the 14& under swimmers, of whom she has spent the majority of career coaching, that she decided to focus her attention on. She signed on to coach with the Olympian Swim Club in 2007. She is now firmly established in our club and in her work with this age group.

At the 2013 Aquatics Banquet Conference held last fall, Lesley took home the Age Group Coach of the Year award. This top award is presented to an Alberta coach who works with a group of swimmers who are primarily 14 and under.

Lesley is a certified level two coach and continues to pursue further education in her chosen field. Currently she is working on attaining her competitions coach certification. She has been selected to represent Team Alberta as a coach over 10 times and has a proven track record of coaching her swimmers to both provincial and national records.

It is her belief that age group swimmers should excel in all four strokes and have great technique. She also believes that with hard work, all swimmers can achieve their goals. Lesley’s aim for the upcoming season is to help all her swimmers succeed and reach their personal goals.

When not on deck, Lesley enjoys her time spent with husband Troy, and two sons; Tyler and Shane as well as her three dogs.

With more than 22 years of coaching experience, all in the Edmonton area, Lesley is back on deck for another season with the Olympians. We are looking forward to hearing her loud familiar whistle, in all its pitches, as she goes about her coaching duties.
