Want to take a class from me? Here’s a schedule of my upcoming classes! Please note some classes are offered more than once per semester. All classes are single-session classes except for Nature Identification for the Beginning Naturalist, which is a two-session class. Each session lasts approximately 2-3 hours for online classes; times vary for in-person classes.

At this time the majority of classes are online; you can read more about why here. Any in-person classes may be subject to being changed to online or hybrid according to local and state regulations, and guidelines set by the venue.

Anyone can register for ONLINE classes regardless of what college or other entity is hosting them; you do NOT need to live in the same area (or even the same state/country!) However, some classes may have region-specific information in addition to more generally-applicable information.

All times are Pacific Standard Time unless otherwise noted.

~Pick the ONLINE class you want at the time and date that work best for you, regardless of where it’s being hosted! Many great options to choose from, at some excellent venues!~
