About us

Polygon Advisory Group is co-founded by Sharon Yip, CPA, and Phil Gaudiano, CPA. Both Sharon and Phil are licensed CPAs in Virginia, United States. They first started working together in 2016 when they were both at the corporate tax department of a Fortune 500 company. After leaving the company one after another, they each formed their own tax practice. In 2018, they began an unofficial strategic partnership and worked on some clients together. After almost two years, they found a natural fit and a common vision. That’s how Polygon Advisory Group was born.

We are fortunate to have a team of talented tax and accounting professionals working with us. We are client-centric and team-oriented. We support each other through all the challenges, and we celebrate our success together. We love what we do, and we are passionate about serving our clients.
