Hi! I’m Coach Brian, and I’ve been part of the Machine Aquatics coaching staff for the past three years. If you’ve ever been to a meet, you’ve probably seen me—the big guy in the camo hat calling for timers!

I grew up swimming competitively in MCSL, PVS (RMSC), and later in college at Frostburg State University. Over the years, I earned multiple MCSL records, won a gold medal at Zones representing PVS, and set school records at Frostburg.

My coaching philosophy is simple: technique, technique, and more technique. I believe swimming should be both fun and challenging because it builds not just strong athletes, but also teaches lifelong values and resilience.

I truly believe Machine is a special program. My daughter swims here too, and I wouldn’t want her anywhere else. The positive environment fosters growth, confidence, and community—helping kids become great swimmers and even better people.

My love for swimming began when I joined my local YMCA team during middle school. I quickly realized it was the one sport I wanted to pursue seriously, which led me to Excel Aquatics in Nashville. There, I qualified for the TN High School State Championship every year in the 200 and 500 freestyle, placed top 10 at state regions, qualified for the Southeastern USA Swimming Championships in the 1650, and competed in numerous open water events.

I attended Western Kentucky University, where I co-founded the triathlete club and graduated in 2011 with a degree in Public Relations and Political Science. After graduation, I worked in politics and met my husband, Tyler, on Capitol Hill. We now live in Hamilton, VA, with our two children.

After stepping away from politics and becoming a stay-at-home mom, I returned to aquatics in March 2024 as a swim instructor at the Ida Lee Recreation Center. Since then, I’ve resumed training and competing in open water events across the region. I’m thrilled to be back on deck with a competitive team and excited to share my passion for swimming and working with kids as part of the Machine coaching staff.
