Thomas Wirth Associates

A garden built by Thomas Wirth Associates is featured in the Smithsonian's own online garden archive — a circular bluestone terrace linking a swimming pool to a greenhouse, pond and waterfall. That's the kind of project this landscape architecture and design firm is known for. Thomas Wirth founded it in Sherborn, Massachusetts in 1982; his son Wesley joined in 1996 and now runs the Sherborn office, with a second office the firm opened in Phippsburg, Maine in 2012. Press coverage over the years backs up the pedigree: a 2018 newspaper profile confirmed the 1982 founding, and a 2011 magazine feature described Wesley personally restoring a coastal bank by pulling invasive plants and replanting native species like sweet pepperbush. There's no customer review on file to draw from, so what's here comes from published design work and press mentions rather than firsthand accounts of hiring the firm. For a substantial residential landscape design, an institutional project, or restoration work along a coastline, Thomas Wirth Associates has the published track record to back it up; since there isn't a customer review to check against, ask for references from a recent, comparably scaled project before signing on.
