Listen to this podcast and be ready to be inspired by these teacher entrepreneurs: Susan Stinson of Southern Regional Middle School (NJ), Carin Zinter of Holyoke Community College (MA) and Carrie Hentz of Hudson High School (WI). What struck me from this conversation was their fanatical level of customer service which is such a key ingredient to the success of any business. Thanks to Susan, Carin and Carrie for sharing your stories. Enjoy!
