What else our students are saying

“I just completed an online bachelor’s degree from another university in an unrelated discipline and Green School is by far the best online course I have taken in terms of both information presented and the interaction, availability, and enthusiasm of the instructors.”

– Green School Participant

“There is so much about Green School that I enjoyed – I can’t stop raving about it. The instructors’ enthusiasm for the course topics was magnetizing. I feel connected to a larger community of gardeners and more equipped with resources as a gardener!”
