Meet Our Team
Evan Demestihas, MD
Founder & Curator, Chairman, Delphi Gardens Foundation
Joyce Demestihas, PT, MA
Founder & Healing Arts Host
Evan and Joyce Demestihas are high school sweethearts originally from Brooklyn, New York, now approaching their golden wedding anniversary. Together, they have built a rich family life, raising four children and delighting in ten grandchildren.
Evan is both a pharmacist and a physician, and Joyce is a physical therapist—careers rooted in service, healing, and deep care for others. After retiring several years ago, they began thoughtfully transforming their home and surrounding property into what has become Delphi Gardens.
Now residing in Buckhead to be closer to their children and grandchildren, Evan and Joyce have been able to dedicate renewed energy to shaping Delphi Gardens as a place of beauty, gathering, and generosity. Envisioned as both a sanctuary and a community asset, the gardens reflect their lifelong values of connection, stewardship, and giving back.
They remain actively involved in the ongoing development and stewardship of Delphi Gardens and the Delphi Gardens Foundation, ensuring that their vision, hopes, and guiding principles continue to flourish—bringing joy and inspiration to the community for generations to come.
