A licensed clinical social worker who for four years has overseen communications for a world-renowned psychiatric hospital in the town will take the reins next month at one of New Canaan’s foremost human services organizations. Ellen Brezovsky will start June 11 as executive director of New Canaan Cares, according to the nonprofit organization’s incoming Board of Directors chair, Sara Schubert. Brezovsky, most recently director of community relations at Silver Hill Hospital, brings wide knowledge of New Canaan families to the role, as well as qualities of creativity and collaboration, said Schubert, who also led New Canaan Cares’s search committee. “She has been working with 13 different communities, so her personal outreach and connections to programming and new speakers is going to be wonderful for us,” Schubert told NewCanaanite.com. Brezovsky said she was “very excited about the prospect of leading up Cares” and “to do justice” to what longtime director Meg Domino has helped build in some 17 years at the helm.
