Mona Langenberg


Mona, the President of GO! St. Louis, was the very first person hired by our founder, Nancy Lieberman. She is our fearless leader and token early bird (and we mean early). Starting out as an intern while an undergraduate at Washington University, Mona has worked in almost every capacity for the organization. She took a short break from GO! St. Louis to travel with her husband, Drew and work as a Childcare & Program Director for two YMCAs doing youth program management and development. Since returning to the Lou, Mona has been the organizational and logistical mastermind behind the youth programs, volunteer program, health and fitness expo and many other race day operations. The only thing Mona appreciates more than a good cup of coffee is a good cup of coffee from a local coffee shop. Mona can often be found running the streets of St. Louis, local trails or after her three children, Cecelia, Samuel and Patrick.

Brian Lyons

Vice President of Race Operations

As the Vice President of Race Operations at GO! St. Louis, Brian oversees all things race related everything from elite runner recruitment to porta-potty placement. With several titles such as collegiate All-American and GO! St. Louis Staff Push-Up Challenge Champ to his name, it is no surprise he is quite the competitor. He has been in love with running since winning his first race in junior high school. Brian’s favorite month is November because it gives him a chance to flex his mean mustache-growing skills. He and his wife, Margaret, a St. Louis native and fellow competitive runner spend their weekends organizing backyard races for their daughter, Lillian and sons, Lukas and Lincoln.
