Our Locations

Diamond Bar

Located at the former Maple Hill YMCA, Premier Swim Academy did a complete facility overhaul, bringing the former outdoor pool into a fully enclosed teaching structure. 100% of the facility was rebuilt and retrofitted to accommodate the new programs, and the addition of the two classrooms will now allow us to provide after school programs and full service summer camps the residents of Diamond Bar and surrounding cities.

Wally Kaspyzycki

General Manager

Wally works as the General Manager for Premier Swim Academy. He has previously worked at Indiana University and Seattle University in their aquatic recreation programs and has been teaching swim lessons since 2012. While finishing his M.S in Kinesiology at Indiana University, Wally was able to focus on Aquatic Recreation and Underwater Physiology and has a passion to stay involved in the field!

Originally from Indiana, Wally’s first job was as a lifeguard on Lake Michigan and his involvement in aquatic recreation only grew from there. He continued to be a competitive swimmer for 6 years, only to switch sports and begin playing ultimate frisbee. He is certified through the American Red Cross as a Water Safety Instructor and Lifeguard Instructor, the Pool and Hot Tub Alliance as a Certified Pool Operator, through PADI as a divemaster and through AIDA as a 1-star Freediver.

Wally loves working with Swim Instructors on “soft skills” and continued education. If you can’t find him at Premier Swim Academy he’s likely with his dog, Naga and there is probably a disc nearby for at least one of them.
