Welcome to a unique small business where our main goal is to teach responsible stewardship of the wide world of plants.

Jen Kettell is a certified arborist and horticulturist serving the New England area. For more than a decade, she worked as a staff horticulturist at Harvard University’s Arnold Arboretum. Now she shares her passion for horticulture through the training she provides to both homeowners and green industry professionals. Currently, she is a consultant for The Trustees’ public gardens, and a guest lecturer and trainer at the University of Massachusetts, the Arnold Arboretum, and the International Society of Arboriculture.

In addition, she collaborates with other professionals through volunteer appointments on the Landscape Advisory Committee for the Wakefield Estate and Arboretum and the Board of Directors at Stearns Organic Farm.

Radiant Leaf has consulted for The Trustees on several projects, and we hope to continue to work with them in the future! Jen did an accurate and thorough tree & shrub identification, assessment, and inventory on two of our properties, and trained and managed staff, volunteers, and contractors to complete a planting of tens of thousands of bulbs on another property. Jen is positive, organized, highly skilled, and open to finding the most efficient use of her multifaceted talents to help us get our projects completed.
