Marc is our founder, director, and lead instructor. He has over 30 years of professional wetlands experience stemming from a distinguished career as an environmental consultant. He has worked on large and small wetland projects around the country and a few overseas. His primary focus has been on wetland assessment, delineation, and design.

Marc is the primary author of most of our wetland course offered. He brings to the classroom a wealth of “real-world” experiences that he is happy to share with his students. He has many stories from the field that demonstrate the practical side of wetlands work.
