The Lisle Park District Sea Lion Swim Team competes in the West Suburban Conference with teams from Downers Grove, Glen Ellyn, Hinsdale, Lemont, Wheaton, Clarendon Hills, and Western Springs. Swimmers are evaluated individually based on skill level and are divided into "A" and "B" Divisions.

The coaching staff will provide an atmosphere of sportsmanship and fun for both beginning and advanced swimmers. This program is primarily for children and young adults who have previously mastered swimming basics and are ready for a more competitive atmosphere. Those considering joining the Sea Lion Swim Team are strongly advised to have completed several swim lesson courses as well as our Intro to Swim Team course. Although this is suggested, it is not required as long as participants meet the minimum swimming requirements listed below.


Swim Team Requirements

If your child does not meet these requirements, please consider our program, Intro to Swim Team.


One (1) length of pool (25 yards): Diving and flip turn experience – completing all levels of swim lessons is strongly encouraged, but not required.

AGES 9-18:

Three (3) lengths of pool (75 yards): A working knowledge of diving and flip turns, in addition to all strokes. Completing all levels of swim lessons is strongly encouraged, but not required.


8 & Under, 9-10, 11-12, 13-14, 15-18. Participants will swim in their appropriate age group based on their age as of Thursday, June 1.


Team suits are not required but are popular with the swimmers. Suit samples will be available at the front desk of the Lisle Recreation Center starting April 6 for fitting purposes. If you would like to receive your order prior to the first dual meet, it is important that you register early and pick up the swim meet parent packet. Swim caps and a team t-shirt will be provided to all swimmers at no additional cost.


Advanced Private Swim Lessons

If you are interested in getting your child some one-on-one time with his or her coach, private swim lessons are now being offered! Class availability is dependent on your coach’s specific availability.

Advanced private swim lessons are geared towards advanced swimmers who are looking for technical stroke instruction but are also ideal for swimmers who are looking to build their confidence with one-on-one private instruction and flexible scheduling. Once purchased, instructors will contact the family to arrange lesson dates and times. All scheduling will be arranged directly between the instructor and family. Lessons are taught by the Sea Lion Swim Team coaches and advanced instructors of our swim lesson program.

NOTE: There may be some scheduling restrictions due to our regularly scheduled programming. Each lesson is 30 minutes. You have the option to purchase multiple lessons.
