Lead Senior Coach


With coaching and leadership roles spanning over a decade, Coach Kyle Kummer has the experience, knowledge, and dedication required to lead a successful team. Kyle began his coaching career with a Park District team in his hometown of Addison, Illinois.   Kyle grew this park district team from 60 swimmers to over 150 in only three summer seasons. The Addison team also won multiple conference championships and had numerous athletes who achieved age group and senior state qualifying times.

After coaching with the Addison park district, Kyle began coaching with Fox Valley Swim where he has coached for the past 7 years. Initially working as the Assistant Senior and Lead 11-12 coach, he eventually grew into the role of the Head 13-14 coach. As a lead coach with the 11-12 group, Kyle had multiple swimmers stand on the podium at Age Group State and Qualify for Central Zones. As the assistant senior coach, Kyle has been a part of teams that qualified multiple NCSA (National Club Swimming Association), Junior National, Senior National, and Olympic trial qualifiers. In 2019, they won Senior Championships and had top individual/relay finishes at NCSA’s. As the Head Coach of 13-14’s, Kyle has coached state champions, state record holders, National Zone camp qualifiers, and nationally ranked individuals and teams. Kyle has also qualified to coach at national level and state level camps. His previous club team achieved USA Swimming’s Silver Medal status in 2019. This status is identified by USA Swimming on an annual basis. The Club Excellence program recognizes USA Swimming’s highest-performing clubs in the development of athletes ages 18 years and younger.

In addition to coaching, Kyle has worked in aquatics management for over ten years. He was previously the Aquatics Director at Labs in Aurora, Illinois.  Kyle is currently the Aquatics Supervisor at the Lemont Park District where he manages indoor and outdoor aquatic facilities, oversees the swim school, develops and manages programs for all ages, coordinates special events, and manages over 100 employees on an annual basis. He holds a C.P.O. (Certified Pool Operator), F.S.S.M. (Food Service Sanitation Management), and an L.G.I. (Lifeguard Instructor) certification which he uses regularly to educate his staff.

With a Bachelor’s degree in Psychology, Kyle holds a unique understanding of athletes at all levels. His motivation, reliability, and positive nature enable him to relate to people at all ages and fitness levels. Kyle’s coaching objectives are to (1) coach athletes of varying skill levels, (2) contribute personal experience and knowledge towards the growth of his team, and (3) promote team building and personal achievement.

Kyle is extremely excited to be a part of FMC Aquatic Swim Team and plans to contribute in every way possible. It’s an amazing opportunity for everyone involved and he feels very fortunate to be a part of it. 


Lead 11-12 Coach


Coach Pierre Ruffin has over 30 years of experience as a swim coach. His bio is different than that of most swim coaches you will read because his story is markedly different than that of most swim coaches. Most notably missing is a list of Pierre’s personal experience as a swimmer.  This is because Pierre does not swim.

He came to swimming by a circuitous route. His four daughters wanted to participate in a sport and swimming seemed like a reasonable and somewhat accessible choice. Pierre attended their practices and events and became a student of the sport. A lifelong learner, Pierre began reading books to advance his knowledge of stroke and technique. To say that swimming changed his life, without being a swimmer, would be an understatement.

His 2014 interview with Gary Hall Sr. of The Race Club in Florida is included in this link

Pierre has coached many outstanding athletes. Below are just a few that Pierre is particularly proud of:

Burley Bokos
Lauren Cox
Jacob Furlong
Jeffrey Hou
Jennifer Iverson

Part of what makes Pierre unique is that he can likely list the names of all the swimmers he has coached and tell you a distinctive story about each. It has been Pierre’s personal approach that has so endeared him to his swimmers. The motto he has hoped to instill in his swimmers is to “never give up”. 

In addition to caring about each of his swimmers, Pierre also demands excellence and that each does his/her best. His attention to excellent form at a young age has prepared swimmers to excel as they advance in the sport.

His enthusiasm and passion for the sport bubbles over like a self-proclaimed kid in a candy store.  He has touched countless lives and is, in part, one of the inspirations behind the creation of FMC Natatorium at Ty Warner Park.

Owner/Manager of
Superior Training

In 2015, Adam became the first coach in Illinois history to build and own their own aquatic training center, Superior Training, located in Willowbrook. Superior Training will now be utilized by FMC Aquatic which will add scheduling flexibility and versatility for the club’s families.

Adam attended Amos Alonzo Stagg High School where he was a three-sport athlete.  He swam varsity for four years; three-year state qualifier; All State senior year; school record holder in the 50-yard freestyle.

As a USA Swimming Age Group Coach, Kirby has worked with a broad array of athletes. He has spent years coaching senior and elite level swimmers, but for the last five years he has focused on, and has had great success with those 12 and under. Kirby believes that stroke technique and skill development is PARAMOUNT for a long, successful, and injury free swimming career. With this strong foundation, Kirby has watched his athletes have success and stay in the sport through high school and beyond.

He has seen the positive effects that swimming has had in ALL of his athletes both in and out of the water. FMC is the opportunity of a lifetime and Kirby looks forward to making FMC one of the premier clubs in the United States.




When Coach Conor Ozog began coaching with Ultimate Swimming in 2015, his main responsibility was working with the senior athletes. Soon thereafter, the numbers grew. Over the following two years, his athletes began qualifying for senior championships, Speedo sectionals and NCSA’s. He continued to progress his athletes from participating to scoring. Through Conor’s leadership, his athletes learned to realign their goals and soon discovered their true potential. Conor looks to further develop his knowledge in all aspects of swimming with his expanding role at FMC Aquatic Swim Team. 

Conor’s passion is assisting athletes in realizing that they have untapped potential and motivating them to compete with confidence. He believes in setting challenging goals and illustrating that commitment and dedication helps foster improvement throughout an athlete’s season. In and out of the pool, Conor puts an emphasis on mental training, nutrition and recovery. Conor personally has many interests so he understands that having balance in life is important. His coaching style reflects that an athlete can have fun, enjoy the sport with teammates and friends while still taking time to enjoy their successes and accomplishments. 

Conor began his swimming career with the Downers Grove Swim & Racquet Club and Express Swim Team, finishing with Westmont Swim Club. Specializing in breaststroke, Conor was a summer junior national qualifier and 4-year Division 1 swimmer. 

When building a pool was first considered, Conor was instrumental in taking the idea from a “sketch on a napkin” to what now stands. He was invaluable in bringing suggestions to the planning process throughout the entire development.   

Outside of the pool, Conor is a Firefighter/EMT at the Western Springs Fire Department. After completing the full fire academy in 2015, Conor went on to EMT school to advance his life saving training. Emergency Medical Technicians are trained to assist with cardiac, trauma and respiratory emergencies, medical assessment and rescue techniques. With the WSFD, he also has trained in vehicle operations, HazMat and fire-ground tactics.  Conor’s training and background bring valuable life-saving skills to the pool deck every day, in addition to a calm and professional response to any emergency situation.
