Jennifer is the Assistant Commissioner of Forestry, Horticulture, and Natural Resources for the New York City Department of Parks & Recreation. In this role, she protects, restores, expands and manages New York City’s urban forest, natural spaces and green infrastructure. 
Jennifer joined the Department of Parks & Recreation in 1997.  She led critical efforts to study the health and mortality of street trees and to quantify the impact of trees on the urban environment.

Jennifer also overhauled the procurement of new trees, expanding the role and capacity of local nurseries to provide a diversity of high quality plant material.
Jennifer has overseen the restoration and management of 2,000 of acres of natural areas including the completion of the first fish passage in New York City, on the Bronx River; the restoration of salt marshes and the planting of nearly 450,000 trees, shrubs, perennials, and grasses as a part of this management.
