Our Story
Gro Pro was founded in 1985 by Peter Grunow — a Greenwich native who learned to love the land from his mother, Betty Grunow, a New York Botanical Garden graduate. After earning a business degree and completing his own studies at the New York Botanical Garden, Peter brought together his horticultural passion and entrepreneurial vision to build a firm dedicated to one purpose: transforming Greenwich properties into places people love to live.
For over 35 years, Gro Pro has grown into a full design-build firm staffed by landscape architects, horticulturalists, construction professionals, pool specialists, and lifelong gardeners. Key team members like Tom Homicki, Landscape Architect, and Ed Fitzwilliam, Construction and Maintenance Professional, have worked alongside Peter for over 30 years.
Peter's roots in Old Greenwich have always made serving this community personal. Gro Pro has been trusted with landmark Town of Greenwich projects including Tod's Point and Binney Park — a testament to the quality our community has come to expect.
