Roberta Sherfy, Education Coordinator | Roberta (Robbie) Sherfy was born in Denton and raised in Denison, Texas. She moved to Austin in 1980 to marry a man she’d known for only eight months. At the time she was teaching kindergarten. After settling in Austin, she taught at a private Episcopal School for five years before going back to teaching at public school. She taught in Pflugerville, Texas for 27 years before retiring.

Robbie has spent time volunteering at All Saints Episcopal Church in their Music program (Front Porch) and ran the Street Ministry programs (Loaves and Fishes) for 7 years before moving into the garden world. In the 90s, she volunteered with the Texas Book Festival, taking care of authors. Later she got a trip to the White House and brunch with Laura Bush while helping with the National Book Festival – the weekend before 9/11, getting home before airlines shut down.

Gardening has always been Robbie’s hobby and passion. She became a Master Gardener in 2016 and has been volunteering at Zilker Botanical Garden as a docent with AAGC. For the past two years, she has been a volunteer in public schools with the Sprout Project, which teaches gardening in a classroom environment. She is also a volunteer at the Lady Bird Johnson Wildflower Center. Robbie feels like she’s gone full circle – when she first moved to Austin in 1980, she worked for the Austin Parks and Recreation Department in their summer program and now finds herself back working with PARD at Zilker Botanical Garden.
