“We are confident that Mark will be a strong leader for our organization through this

transitional period,” Julianne Raymond Flinchum, Board Chair of GRACE

Marketplace, said in the release.

Williams was selected after a three-month search in 2025 after long-time CEO Jon DeCarmine stepped down at the end of 2024. GRACE said Williams is no longer employed by the nonprofit. He served as CEO for nine months and spoke with Mainstreet in December about the role.

GRACE Marketplace did not respond to a request for comments outside its press release.
