Executive Leadership

Heather Emmanuel Ormand
Chief Executive Officer

Heather’s empathy for women seeking long-term recovery for their families lead her to Nexus in June of 2020. At a time when so much was uncertain, the one thing Heather was certain about was the need for Nexus’ services and a safe place for women and their children to turn. Heather credits her own recovery for her personal and professional successes. As a bi-racial woman, albeit one with privileges afforded to her that others may not have had, she values the importance of creating an organization where diversity, equity, and inclusion are not merely a response to a problem but at the heart of the organization’s culture. Leading Nexus into the future is her way of giving back what was given to her and continues to shape her outlook. Heather is a first generation college graduate from the University of Richmond and she brings a unique financial background to the role, being a CPA for nearly 20 years. But, it’s her connection to the clients Nexus serves that cannot be underestimated. Her dreams include a world where her two young children can grow into the greatest expressions of themselves, knowing that their mother loves and supports them, as well as one where women suffering from Substance Use Disorders are accepted, loved, and understood.
