liza.450Liza Mindemann, Park Manager

Liza joined Solar One in the spring of 2015 and took over as the manager of Stuyvesant Cove Park in the spring of 2016 bringing fifteen years experience in the field in a variety of capacities including garden design, installation and management. Growing up in New Hampshire, the majority of her childhood was spent outdoors learning through exploration and adventure, the habits of the natural world. This instilled a life-long connection and love of the earth that eventually led her to pursue a career in horticulture. Her favorite thing about gardening is that it touches on many elements, including the aesthetic, creative and conceptual coupled with the physical, scientific and practical. It is Liza’s vision to draw from elements of her own childhood so that students of all ages can have hands-on experience with nature in this urban environment where such opportunities are not as readily accessible. Current projects at Stuy Cove include turning part of the park into an interactive outdoor classroom where visitors can explore, experiment and interact with the native plants of the park to develop their own connections to the natural world.
