Blue Marlins Swim Team Coaching Philosophy
The goal of the Blue Marlins Swim Team's Coaching staff under the direction of the Head Coach & Buehler YMCA is to provide competitive swimming environment which will give athletes an equal opportunity to develop as individuals and to prepare them for the challenges and rewards of life. Have some fun along the way as well.

By stressing the values of discipline, commitment, hard work and responsibility for oneself, we feel strongly that athletes who give an honest effort in all aspects of the program will be enhanced in SPRIT, MIND, & BODY.

The process of working towards a goal for a qualifying time for a certain swim is the key to developing the values that we are seeking. There are no guarantees that time may be met. What is important is that the athlete took responsibility to prepare to the best of his or her ability in a time seeking effort. Preparation is where the lessons of life are learned. Swimming fast or not swimming fast is not as important as experiencing the feelings of attaining or not attaining a goal. Our hope is that all swimmers, whether they reach their goals or not, still feel good about what they have learned, experienced and enjoyed along the way.

We are here to support your needs. If your questions are related to your swimmers progress in their practice group please contact one of their practice group Coaches.  For all questions related workouts, meets, events, goal setting, other swimming related needs, administrative, safety, or policy issues, please contact Coach Darby.

Kimberly A de Jonckheere

Head Developmental Coach


Kimberly began swimming competitively at the age of  7, with the Green Bay YMCA team. She quickly came to love the road trips and team atmosphere the club provided. She really found her stride in swimming after attending swim camp and moving to Waukesha, Wisconsin where she started specializing in the distance events with Waukesha Express. From the age of 9 she was a multiple event state championship qualifier, but came to love the distance events especially the 200 fly, 400 IM and 1000 free. She swam for Waukesha North High School, where she was a state qualifier and captain of the team her senior year. A demanding academic schedule in architecture and business kept her from swimming in college.

Kimberly has been coaching at the age group development level since 2007 and enjoys making competitive swimming fun and exciting for beginning swimmers.  

She continues to remain active in endurance length events, having run several marathons, half Ironmen and completing her first Ironman triathlon in 2009. Kimberly meet and married her husband, Ryan while doing triathlons and they have one daughter, with another one on the way!

She credits the foundations of discipline, hard work, goal setting, competition, time management and dedication, which she learned from swimming to her successes in life.

Kim A Leidolf

Assistant Coach


Coach Kim started swimming lessons at the age 4 because her mom couldn’t swim.  At age 9, she joined her first swim team, Waubonsie White Waters in Aurora.  At 12, she joined the Naperville YMCA, where she had many good and a few bad coaches.  At 15, she started teaching swim lessons in the summers and continued through college.  At 16, she was one of the inaugural members of the Maverick Swim Team in Naperville.  Coach Kim swam Varsity all four years at Waubonsie Valley High School in Aurora and also played Water Polo.  Her senior year she qualified for state in a Free Relay.  Coach Kim continued to swim in college at North Central College in Naperville for only three years because she graduated early with a degree in accounting.  She also earned her CPA in 2000.  Coach Kim continued to swim after college on a masters team and that is how she got her first coaching job with the Great White Sharks in Wheaton, a developmental team.  She coached for them for 5 years and then moved to the BR Ryall YMCA in Glen Ellyn.  That same year Coach Kim married her husband George.  For 5 years, she was head of the White and Green groups and moved many swimmers up to competitive levels to earn Y state and Age Group cuts.  Upon having their second child, Allison in October of 2009, Coach decided she wanted to be closer to home with her husband and their son George, who was born in December of 2007, so she interviewed here at Buehler.
