In the summers, Greg fulfilled this passion for the outdoors as a fishing guide, spending time between Alaska and Wyoming. After graduation, Greg helped a team of researchers at the Cape Eleuthera Institute in Eleuthera, Bahamas successfully spawn Bonefish in captivity for the first time. Feeling a draw back to the Rocky Mountains, Greg moved to Denver to work in the private water and aquatic consulting field.

Greg’s communication, passion for clean water, curiosity, and broad experience with fish helps Aqua Sierra shine while working in the field or office.
