Who I work with

I serve as a tax and business advisor to family-owned businesses. I help CFOs and owners of small to medium size C corporations, S corporations and limited liability companies (LLCs) solve complex tax matters. I excel at serving businesses in the wholesale/retail sector, however my industry tax experience also includes broker dealers, investment partnerships, digital advertising, chemicals, restaurants and real estate.

My specialty

My specialties include individual and business tax advisory, planning and compliance, as well as introducing my clients to the right Aprio advisors and services that can help them achieve their financial goals. I apply my technical expertise to ensure that my clients pay the lowest tax bills possible and I make myself accessible to answer questions regardless of the size of the client’s business. As a tax director I spend my days, conducting income tax technical compliance reviews, researching tax law and training, directing and mentoring Aprio tax team members.
