I'm Evan Wrenn. I’ve been coaching for over a decade, and the 2025-2026 season marks my 9th with Machine Aquatics. I started swimming later than most—at 13 during my freshman year of high school. I swam through high school and began coaching my local summer league team in my junior and senior years. While attending George Mason University, I continued coaching summer league and USA swim teams while swimming with the club team for four years. After earning my degree in International Relations and spending a few years overseas, I returned to the DC area and rekindled my passion for coaching. I’m excited to help launch Machine Aquatics at the new Chesterbrook site!

I enjoy working with swimmers of all ages and backgrounds, focusing on strong fundamentals and building a lifelong love of swimming. I know there are many unique paths through the sport, and I aim to support each swimmer in reaching their goals both in and out of the water. My groups will emphasize teamwork, fundamentals, and fun, creating a solid foundation for any level of swimming, from building endurance to competing at the highest levels.

No matter the path or goal, I’m committed to helping swimmers develop the skills and confidence to succeed in challenging situations now and in the future.
