Our philosophy

While there’s no shortage of CPA’s in the area, WGA is different.  We understand that our clients are not accountants, and come to us to provide them with the service and solutions they expect from a professional CPA.  From a tax perspective, we know that “conservative” does not always mean “correct”, and we will not allow our clients to overpay taxes for the sake of being conservative.  On the accounting side, we are flexible, and our goal is to be easy to work with. We will go the extra mile to be non-intrusive and to understand how we can help to actually make a difference. 

Our objectives

  • Listen to and learn from our clients.
  • Always keep our value proposition in mind.
  • Prevent problems, don't create them.
  • Represent our client's best interest.
