Sheena is a professional photographer, you can view her work at www.sheena.ca and her courses and workshops at www.photogurus.ca.
If Willis is the engine behind artSIG, Sheena is its spirit, its enthusiasm, its voice of reason, and occasionally the firm hand that keeps it in order. If sometimes it seems that she likes dogs better than people, well, you've seen what kind of people you are. Contrary to popular opinion, she'd rather be nice to everyone. She can be reached at sheena@photosig.com. (Thanks to Marshall for this description.)
