After college, Greg took a year to work as a public school substitute teacher. One year turned into seven. Along the way, he started a mentoring program & a foundation to assist his students. He also has served as a guest lecturer or Scholar-in-Residence for schools & programs. Greg's efforts in &/or beyond the classroom have been featured by media like Education Week & the Education sections of The Washington Post & USA Today. Good Morning America buried a Time Capsule which chronicled the first 100 weeks of the mentoring program. The books based on Greg's story have received kind reviews from media like Teacher Information Network. In some cases, the books have become required reading among future educators. For instance, St. John's University School of Education chose The First Thirty for a course. They have been used with current teachers, too. For instance, a middle/high school in Pennsylvania chose the book for an all-staff common read. Greg has been invited to speak at conferences & events (&/or guest lecture courses for) school administrators, parents, current (&/or future educators). These events have included Durham Association of Educators Summer Institute, Quebec Provincial Association of Teachers Convention, an event for parents & staff at a school in the Pacific Northwest, Thought Leader Series at National Service-Learning Conference, NEIU's Great Service Matters professional development series & Boston University School of Education Pinning Ceremony. In some cases, he has been asked to talk about the role teachers can play beyond class. In other cases, he has been asked to talk about diversity, inclusion & working with students who think & learn differently. To see pictures from a sample of events, click here.
