About Us

C-Sweetener is a not-for profit organization dedicated to helping women benefit from mentorship to become the best leaders they can be. The program was inspired by an opportunity that the Aspen Institute’s Health Innovators Fellowship provided to our co-founder, Lisa Suennen, an experienced healthcare entrepreneur, long-time venture capitalist, and a Fellow of the inaugural class of the Health Innovators Fellowship.  Suennen has used her Aspen Fellowship opportunity to found C-Sweetener in order to advance the healthcare field for all concerned and help create a level playing field that will enable the best entrepreneurs, regardless of gender to win.

Co-founder Lisa Serwin, a long time crusader for healthcare access and a successful health care entrepreneur has joined in this endeavor. Serwin has firsthand experience with the challenges of entering the C-Suite. Lisa has held CEO as well as other C-Suite positions, including CFO and COO.
