NATHAN D. GRISWOLD, ASLA, GRP
Founder and President
Nathan has worked at the forefront of the green roof industry for more than a decade. He has played critical roles in the design, development, sale, construction and successful establishment of nearly 1,000 green roofs across North America. From 2005-2013, he served as the Senior Garden Roof Technical Sales Coordinator for American Hydrotech, one of the world’s largest waterproofing and green roof manufacturers.
Respected for his technical knowledge and hands-on experience, he has proven to be a valuable resource to many design, installation, and owner teams. One of the first individuals to receive Green Roof Professional (GRP) accreditation from Green Roofs for Health Cities (GRHC), Nathan now helps guide and implement the organization’s efforts to advance green roof technology and educate the design community and policymakers on all forms of green infrastructure. He has been an active member of the Green Roof Committee at the American Society for Testing and Materials (ASTM) for more than eight years, helping develop and promote international standards and testing protocols for the industry.
Nathan earned an associate’s degree in plant science from Northwest Michigan College. He holds a bachelor’s degree in landscape architecture, a RISE environmental specialization, and a certificate in landscape and nursery development from Michigan State University.
He launched Inhabitect, LLC to serve as an independent resource for designing, building and growing living architecture that is functional, beautiful and affordable. With his international network of professional colleagues in architecture, landscape architecture, horticulture, engineering, construction and manufacturing, Nathan will bring the right people with the right expertise to every Inhabitect project.
