Head Coach/President
1995-Present (on staff since 1991)

Cheri coaches and oversees the running of the club.  She is the main contact for all things J-Hawk.

Coach Cheri started swimming at the age of 7 and has loved the sport ever since. Her family moved to Whitewater, in 1976.  There was no swim team in Whitewater, so they drove to Janesville and joined the Janesville YMCA team.  There wasn't high school swimming, either, so Coach Cheri ran cross country  and would swim morning practices at the university pool.  Swimming was her passion and still is.  Through hard work and the guidance of an outstanding coach (Coach D), she won state titles, finaled at Y nationals and competed at Junior Nationals.  She continued her swimming at the University of Illinois.  After college, Cheri joined her Mom, Coach D, as an assistant coach for the Janesville YMCA until 1991, when Coach D started the J-Hawk Aquatic Club.  In 1995, Cheri took over as Head Coach and President.  During that time, she had the privilege to coach kids of all abilities.  She's very proud to have coached and developed WIAA state qualifiers and champions, Club state champions and record holders, Junior national qualifiers and champions, 3 Olympic Trial qualifiers and 2 that became top 8 finishers (Emily McClellan placed 6th in 2012, and Bridgette Alexander, placed 8th in 2016). 

No club program in the area has ever had an Olympic Trials finalist, let alone 2, except UW-Madison.  

She loves helping kids achieve their dreams, whether they are going for a personal goal time or shooting for the Olympics.

COACH D (aka Joan Domitrz)
Started the J-Hawks in 1991
Our Stroke Technician Guru/Consultant/Coach

Coach D has been coaching since 1977.  She is an oustanding stroke technician.  She learned how to swim at the age of 29 years old and soon afterwards became a national masters swimmer.  Coach D started coaching at the Janesville YMCA, developing many national qualifiers and a national YMCA champion.  She has coached several Para-Olympians during that time, as well.  In 1989, she doubled up, coaching both the YMCA and UW-Whitewater.  In 1991, she started the J-Hawk Aquatic Club.  Coach D continued to develop state qualifiers and champions (WIAA and club) and national qualifiers (both NCAA and club).  She stepped away from college coaching to help Whitewater HS continue to have a boys swim team.  Coach D coached HS boys for 7 years, where she developed the school's first state swimming champions.  Throughout her college and high school coaching years, she continued to work with the J-Hawks, which she is still currently doing.  She is a master stroke technician and works wherever help is needed on the team.

Coach Derek is a J-Hawk alum, coming up through our program, as an age group swimmer.  He swam for Janesville Craig HS, and competed for Carthage College and UW-Whitewater.  Derek was a high level swimmer, qualifying for the WIAA state meet and USA Speedo Sectionals.  In college, he was conference champion.  Derek has been coaching at Janesville Parker, as the Head Girls coach and the Assistant Boys' Coach.  He has developed several WIAA state qualifiers.  We are very excited to have Derek on staff as he understands the importance of stroke technique, while also building endurance.

COACH Makenna Clark

Hi, I'm Coach Makenna! I grew up in Illinois and was competitively swimming for a club team there for 7 years (which I also coach when I am home for breaks) before moving to Wisconsin! My favorite swim meet with this team is the first time I wore a tech suit at travel meet at the University of Notre Dame; I dropped a lot of time on every event I swam and to this day that pool is one of my favorites! I am now in my third year of college swimming at the University of Wisconsin Whitewater and I am currently studying communication science and disorders with a minor in Spanish. Swimming and working with kids are two of my biggest passions so I love coaching because it brings both of the things I am passionate about together. I had so much fun coaching the J-Hawks for a couple months before summer break and I look forward to seeing both new and old faces this season!
