Meet the person in charge! Tara started with Accounting Support Services in 2002 when we were developing software for accountants. After several years, she left to work as bookkeeper for various clients and a CPA firm and officially returned to the fold in 2014. In 2017, Tara acquired the firm from mother,  Barbara, glad to continue the family business and the reputation of excellence.

Tara works with every new client to make sure they have a good accounting structure and set of procedures. Once this is in place, she will choose a bookkeeper who will best serve the company and make sure they continue to receive excellent service. Tara’s clients include nonprofits and service businesses and she takes on special projects including conversions, job costing and inventory for our clients. She is a Certified QuickBooks Pro-Advisor.


Tara’s off hours are filled with smells of cooking, dirt from her garden and birdsong from the woods near her home in Jefferson where she lives with her guy, Pat and their cat Rona.
