His fine art photographs have been exhibited at the Monterey Peninsula Museum of Art, the Center for Photographic Art in Carmel, California and at galleries and exhibitions throughout California.

Seán teaches regular classes on digital photography and Photoshop for photographers and is an instructor in the photography department of the Academy of Art University in San Francisco.
