ACE Coaching Staff
Kim Berndt ACE Head Coach / Elite / Gold

You walk into a pool and it becomes home - the chlorine smell to the splashing on the pool deck, to the loud deafening sounds of parents and coaches all yelling to swim faster. This environment is a place that most swimmers learn to love. Coach Kim Berndt has made her love of this atmosphere a lifelong career.

Kim started her swimming career in upstate New York. She quickly learned that competitive swimming takes commitment and training.  In addition to her technique and endurance training in the pool, she learned the importance of the mental game needed to achieve one’s goals.  Swimming at the collegiate level, Coach Kim competed at the Division 1 NCAA Swimming Championships. She still holds several school’s records at the University of Miami. Additionally, she has swam all over the world as part of the USA National team competing, placing at many different International meets.

Following her competitive career and graduating from the University of Miami, she transitioned her passion and love for swimming into coaching. She began her coaching career in Miami, Florida. She has vast experience coaching swimmers of all ages, novice to high school. Coach Kim relates to swimmers, bringing her background and experiences to help the swimmers succeed in achieving their goals.

Kim started with the Aquatic Club of Elkhorn simply as a “swim parent” when two of her three children began swimming with the team in 2015.  Upon request of the former ACE head coach, Jay Thiltgen, she joined the ACE coaching staff in 2016. She has coached nearly every ACE group through the years. She has been integral in helping to developing a strong base for team of athletes  in order to help to guide the ACE swimmers through the beginning progressions of competitive age group swimming all the way through the elite levels of competition.

In addition to building a strong developmental base for our swimmers, Coach Kim helps each athlete learn how to work through the struggles and roadblocks that come from competing at a high level no matter the event.  From the pool deck to the real world, Coach Kim believes that there are lots of life skills that come from competitive swimming for kids of all ages.

In March 2020, Kim was asked to take over the team as the interim ACE head coach upon the announcement that the former ACE Head coach awas stepping away from swimming. Coach Kim successfully guided the club and swimmers through the challenging aspects of the pandemic. In the Fall of 2020, the ACE Board of Directors offered Coach Kim the position of the ACE Head Coach. In addition to her responsibilities as the ACE head coach, Coach Kim is also the coaching director for the Elite and Gold groups.

Kim and her husband, live in the Bennington area and have three children.

Upon graduating from Grand Island, Kari went to UNO and swam for the Mavericks under Coach Todd Samland. Coach Jenna and Coach Kari were teammates for three of those years at UNO.

Kari loves coaching all ages, but her favorite thing to coach is stroke development and thus is typically drawn to the younger developmental groups. Often you will hear Coach Kari say that we need to slow it down before we can speed it up.
