Meet Coach Sam
If you book with Beeline MTB, you ride with Coach Sam — the heart and lead coach behind all Beeline programs. Sam brings years of experience, a passion for youth development, and a lifelong love of mountain biking to every session.
Based in Northwest Arkansas, Sam has coached riders of all ages and abilities through organizations like Matthew Mark Foundation, Pedal Kids USA, Trailblazers, Latinas en Bici, and Ozark Bike Guides. Sam has also raced competitively in enduro events across the Southern Enduro Tour, Arkansas Enduro Series, and Ozark Enduro Lite, consistently landing on the podium.
As a PMBIA Certified Instructor, Wilderness EMT, and SafeSport & Heads-Up Concussion Trained coach, Sam takes pride in balancing technical progression with safety, teamwork, and fun. Sam also volunteers as part of Oz Patrol—helping as a trailside first-responder whenever there’s a rider in need, and jumps in as a course marshal at races when she’s not competing.
More Than Just a Ride
At Beeline MTB, we use the bike as a tool to build character and develop the athlete— helping riders grow in confidence and kindness while discovering what they’re capable of. Every ride is a chance to practice courage, perserverance, and teamwork, and every an opportunity to build confidence, character, and community on two wheels.
