I've lived here for a few decades. Used to be a stage actor and am addicted to broadening my sense of the natural world.

What types of projects do you like working on most?

BioBlitzes. iNaturalist. Tigers on Market Street.

How did you hear about Nerds For Nature?

My friend Dan Rademacher....


My name is Liam O'Brien. I'm a naturalist living in San Francisco. I paint/ illustrate trail signs and focus mainly on butterfly conservation.
