BIO: The Environmentalist

Greg grew up in southern California, the son of two former Nebraska farmers. He received his degree in Geography, graduating near the top of his class from UC Berkeley. Traveling for many years, Greg has visited nearly 40 countries on five continents as a researcher, translator, and adventure traveler. 


His teaching career began as a high school Spanish teacher in inner-city Los Angeles as well as in Richmond, CA. 


After receiving his Master of Science in Geography  and Sociology from the University of Wisconsin, Madison, Greg experienced a major spiritual awakening which occupied a few years in his early 30s. This intense time challenged and expanded him greatly.  


He eventually returned to graduate school and completed his PhD in Geography (political ecology) at the University of Texas, Austin faster than anyone in the 70-year history of the department. His research focused on "payment for ecosystem services"  in Costa Rica where he consulted President Luis Solis and his cabinet about national-level environmental policies. 


Having taught for three years at California State University, Northridge, and currently at Laney College, Greg is also a frequent podcast contributor and appears in the Netflix original series, Last Chance U, Season 5. 


Greg, a.k.a. the planet doctor, is an environmental activist, a competitive track and field athlete, and he eats a vegan, organic diet. One of his true joys is zipping around town with his wife and two sons in their electric car.
