Meet Theresa Gren: An Accomplished CPA with a Passion for Helping Clients Save Money I grew up in Lima and currently reside in Wapakoneta. I earned my bachelor's degree in Business Administration from The Ohio State University, and soon after, passed the CPA exam. My primary goal is to help clients achieve their minimum tax liability in a legal manner. When I'm not helping my clients save money I enjoy spending time outside, camping, and running.
