Dennis Greza, Designer / Project Manager

Dennis Greza is a native of Preston County, West Virginia and studied landscape architecture at West Virginia University & The Gloucester School of Arts and Technology in Gloucester, England.

A summer internship of designing and building in Atlantic Beach, NC and Hilton Head Island SC, turned into an eight-year love affair with coastal living and inspired Dennis to build on his solid foundation of presentation graphics, site design and construction & plant materials knowledge. Notable commissions in the Low Country included the Landscape Master Plan for The Mall at Shelter Cove and designing and installing a solar-powered irrigation system for Frank Lloyd Wright’s Auldbrass Plantation.

In 1994, he relocated to suburban Washington DC, and built a client base in the residential landscape and hardscape industry. He joined Main Street Landscape in January 2020 as a Senior Landscape Designer & Project Manager. He specializes in Comprehensive Site-specific Planning, Design and Execution and also enjoys the challenge of small space planning.

In his spare time, Mr. Greza enjoys camping, cycling, kayaking, gardening, architecture, travel, photography, writing and sketching. He is the author of Slow Dance with a Dead Man (Write’s Club Press, 2000), and lives in Oakton, VA with his partner of 28 years.
