Colleen attended Saint Thomas Aquinas College and received a BS in Accounting. After 20 years working for Major Corporations such as  Harsco Corp., Martin Geller CPA Firm & Bloomberg Inc., Colleen spent 8 years raising her children while continuing to work for small business owners in a consulting/bookkeeping capacity. Throughout the years she's noticed small business owners do not have easy access to a reliable and consistent bookkeeping service which led to this new business venture.
