I know firsthand how challenging it can be to grow a successful business while making sure the financial functions are covered.

My focus is on providing responsive, personalized service to my clients. My ultimate goal is to help you, whatever that looks like – whether it be resolving problems, reconciling accounts, and cleaning up your Quickbooks, preparing your annual tax returns, or advising you on more complex matters.
