Delaware Center for Horticulture Appoints New Executive Director

(Wilmington, DE) – The Delaware Center for Horticulture (DCH), a local non-profit organization dedicated to improving the community through the power of plants, announced the appointment of Joanne McGeoch as Executive Director.  


Joanne has more than two decades of non-profit leadership experience, most recently as Vice President for Philanthropy at Delaware Community Foundation and Interim Executive Director at the Delaware Nature Society. Having previously served in leadership positions within the environmental and horticultural sectors and most importantly, in Delaware, she will advance the mission and values of the Delaware Center for Horticulture and guide the next chapter of growth and impact.  


“The multifaceted career path and executive expertise Joanne brings to DCH will undoubtedly expand our programmatic scope and community engagement within Wilmington and throughout the First State, “ said Carrie Wiles, Interim Executive Director. “Our future is bright, and I look forward to seeing the next chapter in DCH’s community partnerships expand and develop.” 


Joanne’s commitment to sustainable landscapes and promoting community engagement through connection to nature aligns seamlessly with DCH’s mission to inspire appreciation and improvement of the environment through horticulture. In her new role, Joanne will oversee DCH’s operations, strategic planning, program development, fundraising, and community outreach. She will work closely with the Board of Directors, staff, volunteers, and stakeholders to build upon DCH’s foundation of connecting communities with the power of plants. 


“DCH combines my deep experience and passion for connecting people to the natural world, and building more sustainable, resilient communities,” said Joanne McGeoch, Executive Director. The organization is at an exciting inflection point in its more than 40-year history, and the mission is so relevant to the need for nature-based systems that build resiliency, support biodiversity, and improve the environment. I am honored to be joining the organization, and look forward to working with our staff, board, volunteers and partners to cultivate greener neighborhoods that are healthier, beautiful, and ecologically sustainable.”
