What Clients Say

“I have had the privilege of working with Esther Mensah-Sullivan and Impact Numeric for the past three years as she's supported Living Cities, the National Community Development Initiative, Inc. Beyond technical competence, Esther discerns when "best practice" aligns with the right practice for her clients.

 

She specializes in nonprofits and small businesses and provides a full range of services, from financial statement compilation to audit readiness. Her pro-active communication ensures clarity, and she is exceptional at reducing complex accounting issues into easily understood terms.

 

What truly sets her apart, however, is her balance of collaboration and leadership. Esther is a team-player who knows when to lean into directing and instructing.

 

For all of these reasons, I wholeheartedly recommend her services.”

Financial Leadership Built for Your Mission
