Carrie Ellis
Carrie L. Ellis is the Principal Consultant of Celestial Consulting LLC where she uses her more than 20 years of experience to advise and partner with managers, teams, and organizations as they navigate workplace complexities; she knows first-hand the challenging work of leading.  Through her career, with roles including the Vice President of People Development at Teach For America and the Director of Project Management at KaBOOM!, Carrie has developed skills in small and large team management -managing from 3-26 people, effective program design and implementation, strategic thinking and planning (she and her KaBOOM! team were responsible for the completion of projects with over 1,400 communities and 200 funders), and nuanced partnership development techniques. Additionally, as a diversity, equity, and inclusiveness specialist, Carrie partners with teams to help them enact culture-focused, equitable solutions that resolve difficult situations, create sustainable change, and result in better organizational outcomes.

A certified coach, Carrie leads with curiosity, compassion, joy and a belief in people’s abilities and capabilities to do more than they thought possible. As one Executive Director client described, “[Carrie] is extremely competent on the toughest of all topics – people: she gets to know people very well, she understands their perspectives and uses that to figure out how to improve situations, performance, happiness, etc.   She has excellent judgment, both real time and stepping back to flesh out a bigger picture course of action.”  She is a skilled listener who is able to discern what is most important to people and situations and then translate what’s important into strategies and actions. These skills - coupled with her ability to think critically, focus on results, and develop the systems and processes that enable people to succeed - underpin Carrie’s reputation.


Carrie graduated with honors from Spelman College and the University of Southern California.  As an alumna of the American Express Leadership Academy, she was selected to participate in the 2015 and 2018 Global Alumni Summits in New York with other social justice leaders from around the world.
