Some 2024 classes will be held online, and some in person at Brookhaven College. We will have small-group, in-person experiences – nature walks, field trips, meet-ups to see Master Naturalist Projects and places to volunteer, and also for you to meet and get to know fellow Master Naturalists.

Learn. Volunteer. Repeat.

*Note: JBS is the best place in town for wetlands education.  There will be two trips to JBS on the calendar, and we are hoping that we can get 100% of trainees registered in one of these Saturday morning classes.  Understanding that Saturday mornings may not work for everyone, I’ll work with those of you who can’t attend the JBS trips to try and schedule an alternative option.
