Coaches

Sierra Miller began swimming at age five in Cape Girardeau and grew up competing with the Gator Swim Team and River City Aquatics. She swam for Saxony Lutheran High School from 2012–2016, medaling in all eight of her conference swims, primarily in sprint freestyle and backstroke. Her experience on deck includes serving as a lifeguard, head lifeguard, and swim instructor for the City of Cape Girardeau at Central Municipal Pool and Cape Splash. From 2021–2023, she co-coached the combined Saxony Lutheran and Notre Dame Regional High School girls' swim team, helping swimmers new to competition develop their technique and confidence. An active adult swimmer herself, Miller understands how a person's relationship with the pool can evolve, from racing as a child to finding fitness, routine, and community as an adult. Returning to RCA as its Masters coach brings her swimming background full circle. Her approach emphasizes clear instruction, individual goals, and steady progress, with room for adults who want to compete, return after time away, or make swimming a consistent part of their lives.

A native of Atlanta, Georgia, Brewer is the 1998 100m Backstroke National Champion and 10-Time USA Swimming National Team Member. As an 18-time All-American at the University of Georgia from 1994–98, he won three SEC individual titles and served as team captain. He swam professionally, co-authored The Olympic Dream and Spirit, and overcame a debilitating back injury heading into the 2000 Olympic Trials — then came back to win a national championship, a US Open Championship, and qualify for multiple national teams. In 2004 he earned his Master's in Sport Science and served as VP of Premier Management Group, managing Olympic swimmers including Aaron Peirsol and Amanda Beard. He later served as Head Coach of the Army's Wounded Warrior Program before founding RCA. “There is no magic in coaching,” Brewer says. “We train at race pace and with attention to technique since that is how we want it on race day. Every day is race day.”
