Joellyn’s favorite place in the world is Islesboro, Maine where she enjoys hiking in the woods. Her perfect workday would include bagels, coffee, and a busy day working with colleagues concluding with all objectives being accomplished. Sounds like a good planner, doesn’t she?!

Joellyn enjoys gardening, taking care of her horse, Cooper – a 20-year-old thoroughbred – and cooking. She has a daughter named Emily with her husband, Nate and a Collie Shepherd named Ellie.

We provide services to both public and private clients in civil engineering, landscape architecture, municipal services, planning, geology, and surveying. Please contact us at or 717-898-3402 for more information. #DMADelivers
