I first came to the Arboretum in 2007 as an Isabella Welles Hunnewell intern and returned the following fall as the Curatorial Fellow; I have held my current position since 2009. I manage numerous areas on the grounds, most notably the Leventritt Shrub and Vine Garden, but also the viburnums, Linden Path, and the meadow located at the Arborway entrance. I have also taught classes through the Adult Education program and serve on the Arboretum’s Integrated Pest Management Committee.

I enjoy giving back to the community, volunteering regularly with Boston river clean-up efforts, the Emerald Necklace Conservancy (ENC) Kelleher Rose Garden, and as a member of the ENC Maintenance and Restoration Working Group. I was awarded Volunteer of the Year by ENC in 2011. In addition to my work with ENC, I am also involved with the Neponset River Watershed Association as a beetle rancher with the Purple Loosestrife Project for wetland restoration and as a water quality monitor within the Citizen Water Monitoring Network. With Kit Ganshaw, I provide scouting information for the East (Boston) region for the University of Massachusetts Landscape Message.

Prior to my arrival at the Arboretum, I worked for Sheridan Nurseries, Maple Hill Tree Services, the Toronto Civic Center (now the Toronto Botanical Gardens), and the Niagara Parks Botanical Garden and Butterfly Conservatory. Besides horticulture, I am fascinated with the insect world and can often be found experimenting or out collecting, day or night. I enjoy traveling to gardens, arboreta, parks and forests. I also enjoy the symphony, foreign films, hiking, and hockey.
