Principals Steven S. Cushing, PE, & Harriet A. Henderson, RLA, began Cushing & Henderson in 1986 and are based today in Unionville, Pennsylvania.

Master’s level concentrations, combined with a history of writing and lecturing, add depth to the approach they bring to project design and development.

Their combined, extensive backgrounds and broad expertise advance and sustain the belief that landscape architecture has relevant connections to architecture and horticulture.

With this unique, interdisciplinary approach, Cushing & Henderson has been creating culturally dynamic and inviting landscapes throughout Pennsylvania and the Eastern United States for over 30 years. Within their body of work are notable institutional projects, commercial and residential properties.
