“Cary Chessick is a successful serial entrepreneur. He has been a driving force in multiple companies and behind multiple social movements. Through his leadership as CEO, Restaurant.com earned acknowledgement by the Chicago Tribune of being one of the top 100 places to work in Chicago and Wired ranked it among the top 10 companies you want to work for outside of Silicon Valley. His new venture plans to bring this culture to other companies via a scientifically supported curriculum. With his proven track record as an entrepreneur and a leader, I am glad to be a part of Positivity.”                  -
