Lara grew up playing in Terrapin Creek, which ran behind her childhood home outside of Columbia, about a mile from the Missouri River. She's since lived, studied, and taught in Iowa, Switzerland, Ecuador, and the Galapagos Islands. After living and teaching abroad, she returned to her home state to work for Columbia Public Schools as an English as a Second Language (ESL) teacher.

Dave Combs

Fleet Manager

Dave's love of spending time outdoors led him to the fisheries and wildlife program at Mizzou. After graduating he embarked on a 15-year adventure as a biologist on the Missouri River. During that time, he spent countless hours tracking the endangered Pallid Sturgeon on the Missouri River from Yankton, SD to St. Louis, MO and even on the Yellowstone River in Montana. When not tracking in the field he was busy maintaining the fleet of research vessels, designing and building scientific equipment and conducting boat operator and water safety training.

Becca Ray

Becca graduated from Mizzou in 2009 with an English degree and a love for Columbia’s quirkiness. She spent a childhood floating her native Ozark rivers and now explores the Big Muddy with her own two kids, her partner Josh, and their little dog Penny. Becca loves a good story and finds that the river is full of them (and tires!). She is dedicated to plucking out the best tales (and tires!) to help build MRR’s legacy.

Jo Gebelt

Education Assistant

For the past two years, Jo worked as the Education, Volunteer, and Outreach Intern at Mueller State Park with Colorado Parks and Wildlife, and before that served as a Unit Director at a Girl Scout camp in San Diego. They hold a B.S. in Parks and Recreation from the University of Utah. 

Jo grew up in the Rocky Mountains and will take any excuse to be outside — birding, rock climbing, snowboarding, camping. One of their favorite ways to do that last one is backpacking with a set of watercolors and a good book. Summers in Minnesota taught them to fly fish and canoe, and gave them an early love of rivers. They're ready for a new landscape and a season on the Missouri River.
