Tom Wyllie Head Coach

My coaching career began at age 18 when I served as a volunteer coach for a local summer swim club in Pennsylvania working with the 8 & unders (and loving every minute of it!). While pursuing my undergraduate degree, I served as an assistant coach for the Birmingham Blue Dolphins, a nationally prominent year-round YMCA program in Michigan consisting of 300+ team members where I worked primarily with the 12 & unders. During graduate school, I served as Head Coach of the Gonzaga College Prep High School Boys Swimming & Diving Team in Washington, D.C. After grad school, I returned to Michigan and was hired as the Head Coach for the Birmingham High School Boys Swimming & Diving Team where though I didn’t know it at the time, I would spend the next 24 years. While at Seaholm, I achieved a degree of success that, among other accomplishments, includes:

  • 4 top ten National Interscholastic Swim Coaches Association (NISCA) “Mythical” National Championship finishes
  • 64 NISCA High School All-America swimming performances
  • 4 Michigan High School Athletic Association (MHSAA) Division 2 State Championships
  • 25 MHSAA Individual State Champions
  • 18 MHSAA Relay State Champions
  • 12 MHSAA State Class/Division Records
  • 2 MHSAA All-State Records

Needless to say, competitive swimming has been a passion of mine for quite some time and I am extremely thrilled to now be serving as Head Coach for Velocity Swimming. With a great team of assistant coaches, a supportive Board of Directors and a wonderful group of swimmers eager to learn, the future looks bright for our team. When I am not coaching, I enjoy working out and running on trails, however, after finishing my first run, one thing I quickly learned is that what we call hills in Michigan are simply speed bumps in Wenatchee.

Carolyn Petersen Assistant Coach

I grew up playing different sports for every season from basketball in the winter to my dad coaching tennis summer camps. One of the sports I participated in each summer with the City of Wenatchee was swimming. After the City, I swam with Darcy Bruggman and Carolyn McGee at the WRAC. My favorite memories from sports came from swimming-hanging out with friends during those long meets! I did not swim year round until my sophomore year of high school, again with the WRAC program. I did swim all 4 years in high school and joined Central’s rec team during my undergrad years. I received my undergrad in Psychology from CWU in 2012 and continued on for my masters in Experimental Psy. After college, I returned to Wenatchee and worked as a para-educator at WHS in the aquatics department. There I was recommended by the head coach, John Pringle to become a coach with Velocity. I started the fall of 2014 and loved it since. My first year I worked along side coach Kathy and Trent with the copper group. Since then I have worked with each age group and increased my knowledge both on deck and administrate tasks behind the scenes. 

I am looking forward to this season as I have decided to make Velocity Swimming my main career path and I couldn’t have had a more welcoming and energizing team to work with!

Please feel free to email me with any questions about myself or the team! 

Kathy Elwyn Assistant Coach

My interest in swimming started when I was eight years old with the Wenatchee Swim Team, when my best friend encouraged me to try out.  She convinced me swimming was the “best sport ever”, and over the years I have had some level of commitment to the sport I love and enjoy.  After years of competitive swimming at the age group and high school level, I swam at Pacific Lutheran University, majoring in Physical Education with emphasis in Exercise Science.  I started my coaching career while in high school, helping with the club team as well as the summer swim team.  I have worked as an assistant coach with the Montclair YMCA age group and masters teams, as well as the WRAC swim team and now Velocity.   Outside of swimming I am a Nurse Case Manager at Confluence Health, and have three children, Kayli, Connor, and Austin.  Through swimming at PLU I met my husband, James, who was the Wenatchee High School girls and boys swim coach before passing away in 2020.  We encouraged all three of our children to swim because we realized the lifelong value of this skill, and recognized that swimming offers not only fitness benefits but teaches you about goal setting and perseverance, such invaluable skills to carry with you long after leaving the sport. I enjoy supplementing my nursing career with coaching, with the goal of helping novice swimmers get excited about the sport I so much enjoy.  Two accomplishments of my swimming career were inductions into both the Wenatchee High School and PLU’s Hall of Fame, both secondary to the life long skills I have gained from this sport.

Trent Grigsby Assistant Coach

Unlike all these other amazing coaches, I never swam for a club team.  I kind of stumbled into swimming by accident.  My freshman year in high school, the basketball tryouts were being held at 5 am.  Not an early riser, I decided to go out for the water polo team as their tryouts were being held at a much more reasonable hour.  Little did I know, I would soon be doing daily double workouts during the water polo season and then continuing those grueling workouts during the ensuing swimming season.  I played water polo and swam throughout high school, going to state my senior year. Following high school, I swam for three years at the University of Puget Sound.  I graduated from UPS with a degree in Computer Science and worked for a small mortgage software company in Gig Harbor for several years. Our family relocated to Wenatchee in 2010 and my boys joined Velocity in October of 2011.  I feel honored to be able to help out our team and enjoy working with the kids and watching them grown and develop into amazing athletes and human beings. Outside of swimming, I work as a Control Systems Engineer for the Chelan County PUD. I enjoy boating, wake-surfing, paddle boarding, and wood working.


Jana Sutton Assistant Coach

My mother was a competitive swimmer, and there was never any doubt that her children would be swimmers as well. I grew up spending all my free time during summers swimming. Being in water has always truly been my “happy place.”

I first became involved in Velocity when my oldest began swimming 10 years ago. My family quickly found a “home” on the team. At one time all three of my children swam for the team.   My husband and I also quickly learned that not only can swimming be a great way for kids to get involved, it is great for the whole family.  Both my husband and myself have had leadership opportunities on the team, including  both if us serving as Board Presidents. I never would have imagined 10 years ago the friends I would make because my son wanted to swim!

Coaching has always been a passion of mine, and I have spent many seasons coaching my kids’ various sports.  I am truly excited to have the opportunity to coach swimming, and I hope I can share my love of water with all youth that I work with.

Off the pool deck I work as a 5th grade teacher, enjoy spending time with with my husband and kids, and love enjoying the great outdoors in the Wenatchee Valley.

Grace van der Merwe Assistant Coach
Benjamin Grigsby Junior Coach

I started swimming with Velocity in 2011 when I was 7 years old.  Coach Kathy was my first coach.  I started coaching the Minnow group in 2019 as a volunteer coach.  I started coaching as a way to give back to a program that has meant so much to me the past 10 years.  I enjoy working with the younger swimmers and teaching them stroke technique.  Last year, during COVID, I completed my coaching credentials and have started working with the Barracuda and Piranha groups. 

I am currently a senior at Wenatchee High School and I am looking forward to swimming in my final year of high school swimming.  While I don't plan to swim competitively in college, it is my goal to continue swimming in some capacity as I believe swimming is a life-long, healthy activity.  In college I plan to double major in Aerospace Engineering and Computer Science.

Outside of the pool, I enjoy video gaming, watching tech videos, have an obsession with electric vehicles, and I like wake-surfing and paddle boarding.

Wyatt van der Merwe Junior Coach
I started swimming competitively on a summer swim league in 2012 before joining Velocity in 2014. While swimming over the years, I became a certified lifeguard and Water Safety Instructor. I enjoyed teaching lessons and coaching for a summer league swim team in Quincy, so I completed the rest of my required certifications to coach and have started coaching the Minnows group and occasionally Barracudas, Piranhas, and Sharks when needed.
I am currently a homeschooled senior. I don’t have any plans to swim in college, but I will continue to stay involved in swimming and Velocity as long as I can. Beyond high school, I’m planning to graduate from a trade school or became Firefighter in the Water Rescue Unit.

Apart from swimming, I enjoy video games, tennis, reading, and water skiing.
