A 34-year veteran classroom teacher, research, author, and health, fitness, and longevity practitioner. Jim's vast work has launched him into the national spotlight as an expert in rapport-building in schools and engaging even the most reluctant learners. Jim has been featured in the Huffington Post, Edutopia, Principal Leadership, Ohio Schools Magazine, Talks With Teachers, Join Up Dots, and many other education resources. A longtime educator, author, and entrepreneur, avid reader and researcher, Mark became interested in-perhaps even a bit obsessive about-health, fitness, and longevity when he joined the After-50s club in 2014. He is the author of 10 books, including ROLE Reversal (ASCD, 2013), Hacking Education (Times 10 Publications, 2015)--the first book in the internationally-renowned Hack Learning Series-and Hacking Life After 50 (Times 10 Publications, 2023)--the first book in the Hack Learning Life Series.
