Katie Chevalier Head Coach
Coach Katie brings over two decades of swimming and healthcare expertise to the Concord YMCA Sailfish. A lifelong swimmer who began competing at age 7 with the Lake Champlain Waves in Northern NY—where her parents ran the team as head coaches—Katie continued her swimming career at Clarkson University, specializing in the 200 Breaststroke and 200 Backstroke while earning Academic All-American honors.
 
Katie's passion for athletics and sport biomechanics guided her to physical therapy, where she has excelled for over 20 years in outpatient care. She holds a Bachelor of Science in Business Administration/Pre-Physical Therapy (2003, graduated with Distinction), a Master of Physical Therapy (2005), and a Doctorate in Physical Therapy (2008). She currently owns and operates Meredith Bay Physical Therapy, where she continues to serve patients as a practicing physical therapist.
 
Her coaching journey began with the Wavemakers in summer 2018, where she advanced to Head Coach in fall 2022 before joining the Sailfish as Head Coach in summer 2025. As a swim parent herself with two children currently on the team and a third starting soon, Katie brings a unique perspective that combines her professional expertise with firsthand understanding of the swim family experience.
 
Coach Katie is passionate about combining her biomechanics expertise with her lifelong love of swimming to help young athletes achieve their personal goals both in and out of the pool. She believes every swimmer should have the opportunity to become the best they can be—understanding that while not every athlete will become a Katie Ledecky or a Michael Phelps, each swimmer deserves the chance to reach their own highest level of greatness, whatever that looks like for them.
 
When she's not coaching or working, Katie enjoys spending time at the beach or waterskiing with her family, running outside, and open water swimming with friends —staying true to her lifelong love of being active in and around the water.

Brad has six kids, and has coached all of them during their time in age group swimming.  He's been coaching for over 10-years including with the Concord YMCA Sailfish since 2018.  One of his favorite things about swimming is that it is a sport that can be enjoyed at all levels, and simultaneously a sport that rewards hard work and mental fortitude.  He loves to see swimmers set goals and work hard in the pool to achieve them.    
 
Outside of the pool, Brad has spent a career as a professional geologist and environmental consultant performing environmental investigation and remediation projects for contaminated sites throughout the United States, Europe, and South America.  He also enjoys upland bird hunting, competing with his dogs in field trials, and fly fishing.

Kim Schoembs Coach

 

Coach Kim learned to swim in Deep Creek Lake, Maryland when she was 3 years old and spent countless hours in the pool over the years.  A member of a highly decorated high school team, Kim learned about competitive swimming from an Olympic qualifying coach who led the team to over 400 wins and 26 section titles.  Under her leadership, Kim experienced the art of dovetailing fun and camaraderie with discipline and success.  She excelled in the 100 back and 100 free and went on to qualify for Western Pennsylvania Interscholastic Athletic League championships.
 
Kim holds bachelor's and master’s degrees from the University of Pittsburgh and works as a leader of Financial Planning & Analysis at Highmark Blue Cross and Blue Shield.   
 
Inspired by the impact a coach can have on a young person’s life and by the strong, positive correlation between sports participation and academic performance, Coach Kim is enthusiastic about working with athletes to set and achieve goals.  As an analytical expert, Kim identifies and analyzes patterns in the pool and works to reinforce positive behaviors and break performance-limiting habits. 
In addition to coaching, Kim is also a dedicated Masters swimmer at the Concord Y and can often be found there training with her friends and teammates.
Eva Piernas Coach
Coach Eva began swimming at age 6 in France and swam in high school at The Bolles School, at Simmons University collegiately and continues to swim after college. She earned a bachelor’s degree in Neuroscience and a minor in chemistry. 
 
Eva volunteered as a swimming coach in high school and really enjoyed it, which is why she decided to join the Concord Sailfish as a swim coach. Her college events were the 1650 and 500 freestyle. 
 
Her favorite part of being a swim coach is “teaching someone who doesn’t know how to swim to swim”. She meets each swimmer where they are in their swimming journey, works with them and always aims to make practice fun. Celebrating any type of progress at any level, big or small, she is always rooting for her swimmers no matter their goals. Her goal is to have fun with her swimmers but to also give her swimmers confidence both in and out of the pool. 
 
Eva is applying to medical school and hopes one day to become a doctor specializing in physical medicine rehabilitation.
