    Join us February 2nd from 5:30-7:30 and step into leadership and help our garden thrive!  

    The Jordan House Gardens are growing—and we’re inviting passionate, capable volunteers to help guide what comes next. Join us for a short, friendly info session to learn how you can make a real impact behind the scenes.

    We’re filling 5 key leadership roles:

    • Garden Coordinator – keeps the big picture blooming
    • Volunteer Lead – recruits, welcomes, and supports our hands-in-the-dirt helpers
    • Education Lead – connects history, gardening, and learning
    • Events Lead – brings garden moments to life for the public
    • Communications Lead – shares our story and seasonal updates

    No prior leadership title required—just curiosity, reliability, and a love of history, gardens, or community (or all three). Time commitment is reasonable. Impact is real. Dirt under your nails optional.

    Come listen, ask questions, and see if one of these roles fits you. Please register on this website if you plan to attend. If you are also  interested in one of the leadership roles above, please use the signup genius.
