Kathleen Liebowitz
Kathleen LiebowitzExecutive Director

Kathleen Liebowitz joined the Toward Zero Waste team as it became a non-profit in January 2020 after volunteering for numerous organizations in the Triangle and working as the Volunteer Coordinator for the Step Up organization. She established the volunteer program with Toward Zero Waste as the first Volunteer Director for the organization by developing the Volunteer Handbook and the onboarding process. At the same time, she shared the role of Raleigh Community Director with Dawn Comfort. Both of these roles were a challenge to evolve due to the COVID shutdown. In spite of this challenge and with the help of the Toward Zero Waste team, Kathleen was able to expand the Toward Zero Waste volunteer base by 30 plus volunteers placing them in roles that best suited their interest and skills. With Kathleen’s help, the Raleigh community program also was able to advance during that time to include a quarterly litter sweep, and a compost drop off at North Hills Midtown Farmers’ Market.

In February of 2023, Kathleen stepped into the role of Executive Director where she plans to work with the North Carolina General Assembly to pass eco conscious legislation, as well as collaborate with other local non-profits and the Toward Zero Waste team to work together to continue Toward Zero Waste’s mission of promote waste conscious living in North Carolina.

In her spare time, she enjoys Pilates, reading, and spending time with her husband, two teenage children and her Wheaten Terrier, Dempsey.

Leigh Williams
Leigh WilliamsCo-Founder

Leigh Williams lives in Cary, NC with her husband, two teenage daughters and a Basenji named Millie. Leigh received her Bachelor of Science in Nursing from Clemson University in1996 and enjoyed several years exploring the western United States as a travel nurse. She later moved with her husband to Europe where they spent 6 years as expats in Switzerland, Italy and England.

Leigh started moving “toward zero waste” in September of 2015 after reading Bea Johnson’s book Zero Waste Home. Bea’s single jar of trash a year for a family of four didn’t seem possible for her own family, but Leigh knew she could do better and was inspired to try.

Wanting to share the journey, Leigh teamed up with Dargan Gilmore after meeting her on an international zero waste Facebook group. Together, they formed Toward Zero Waste, with a desire to educate and inspire others to move toward a zero waste lifestyle.

On January 1, 2019, she started her own version of a trash challenge to see how long it would take her family to fill up their 95 gallon curbside bin. They pulled their bin to the curb that year at the end of November!
