Sabina Carr
Chief Executive Officer

Sabina Carr is the chief executive officer for the San Antonio Botanical Garden. Sabina joined the San Antonio Botanical Garden in the fall of 2019 after an extensive national search. She arrived at a significant juncture for the public garden that had just transitioned to privatization in January 2019. Sabina directs all operations for the 38-acre public garden located in the heart of San Antonio’s cultural corridor, and under her leadership oversees fundraising, education, marketing, business administration and horticultural efforts with an annual visitation of 170,000 and a membership household base of over 11,000, doubled from 5,000 households during her tenure.

The Botanical Garden recently completed a successful $40M capital campaign that transformed the garden with stunning new gardens, facilities and amenities, including a culinary garden, an outdoor teaching kitchen, family adventure garden, and new state-of-the-art event and education center. Sabina has activated these new spaces with expanded hours, new events such as the Sips & Sunset in the Garden series, new art exhibitions including the world debut of Frida Kahlo Oasis and Origami in the Garden², and horticulture exhibitions such as Wildflowers in the Garden & Orchid Weekend. This activation has attracted more earned revenue and served to broaden audiences while connecting more people to the importance of plants in our lives.

She is Past President of the Board of the American Public Gardens Association, a national network of over 600 member gardens and over 9,000 individual members in 14 countries. Prior to joining the San Antonio Botanical Garden, Sabina was Vice President, Marketing for the Atlanta Botanical Garden where she helped lead the garden’s impressive growth over 15 years by quadrupling three key areas: annual operating budget, annual visitation and household membership.
