After college and before joining HG, Randy cut his teeth in landscape architecture working for golf resort design firm George Golf Design. At HG, he worked closely with Dave to learn the planned development sector, but then left for a brief 2-year stint with one of our community development clients, The Cresent Group. HG rehired him in 2017, and with almost twenty years of experience, Randy is astutely aware of budgeting and constructability on both sides of the aisle, and how to minimize a client’s expense without sacrificing a project’s delivery. He is a graduate of the Davis School of Agriculture, Natural Resources and Design at West Virginia University, and possesses a rare skillset of designing and managing projects from the very small to the sizable, i.e., a large mixed-use development with varied amenities, and every variable in between.
Our vision is to be the firm of choice for clients 
who demand attractive, functional site design.
