Harbor District Staff


Executive Director

414-643-1266 x1

As executive director, Lilith gets to draw on her passion for great urban environments. She enjoys the many puzzles that come with the two sides of her job: revitalizing a complicated and challenging district and building an organization from scratch. In her work, Lilith relies on the perspectives and communication skills she gained living and travelling in other cities and countries; the tools and frameworks garnered from a liberal arts education and an MBA; and the balance between patience and push that she strives to master as a mother.

Her career has focused on the intersection of business, community, and environment, from helping Mexican farmer co-ops obtain organic certification, to building Milwaukee’s Menomonee Valley into a model for sustainable development. Lilith lives in a decommissioned firehouse on the east side of Milwaukee with her husband and two children.


Natural Environment Program Manager

Aaron Zeleske is the Natural Environment Program Manager at Harbor District, Inc. Aaron leads our efforts to improve the ecological functioning of our corner of the city, focusing on improving habitat for fish and wildlife and green infrastructure practices that improve water quality. He works on several habitat restoration projects on the Kinnickinnic River, manages innovative projects like the Habitat Hotels and Trash Collector, and seeks to creatively incorporate environmental principles into everything happening in the Harbor. Through these projects and programs that connect people to nature, Aaron works to change how people think about and relate to the plants and animals with whom we share our city and our world. “This is some of the most important work we as a species need to undertake in the coming decades. We must learn to balance our needs with the needs of other living things like climate change and Anthropocene mass extinctions pick up steam. Even our developed, industrial harbor can be enhanced as a better functioning part of the ecosystems inside of which every human activity is nested, and improving its ecology will make a difference.”

Prior to joining Harbor District in 2019, Aaron spent over seven years working at Milwaukee environmental organizations, River Revitalization Foundation and Urban Ecology Center. He has a Masters in Nonprofit Management from Marquette University, where he was a recipient of the Trinity Fellowship. Outside of work, Aaron is a ceramic artist and avid cyclist and outdoorsman.
