I served as an Extension Horticulture Specialist at the University of Vermont for 35 years until my June 2016 retirement.  In my Extension role, I provided information and programming to the industry of Vermont, region, and North America.

Home gardeners in Vermont and surrounding areas know me from my frequent television appearances on the regional Across the Fence program, periodic radio interviews, and monthly news articles.  Many people join me yearly on local and regional gardening tours.  As a Professor, I led an active research program on all aspects of perennial production and overwintering, and continue to collaborate with Burlington Parks and Recreation on the Waterfront Display Gardens featuring new annual flowers.
