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

Jen Kettell is an arborist and horticulturist serving the New England area. She is a recent graduate of the American Society for Consulting Arborists (ASCA) Academy, an advanced professional training for experienced arborists.

As the owner of Radiant Leaf Consulting, 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 (ISA).

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.

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.
