Who We Are

Liz sits on a bunch of boards, speaks locally and nationally frequently, and is always active, especially in the technology startup community in Phoenix.

She is a shareholder, and CFO and Rebel Rock, where she assists clients with GAAP compliance, financial modeling, financial reporting, and general financial accounting inquiries.

She is currently the loving mother to two step-children and three dogs. If you’re in search of a good conversation topic, she could go on for hours about dogs in general (but particularly hers). Also sloths. Her passion for each is only rivaled by her love of travel.
