Our Story

In 1954, founder G. Victor Herro, had a passion to help family and friends with their tax and accounting needs. His success was built on fostering relationships and providing the best possible tax and accounting advice. Victor felt that communicating well with clients and educating them was another key to success. He quietly grew his practice and in 1975, he moved his business to the Germantown, Wisconsin area. His passion of providing superior service to his clients was passed to his son George and also daughter Jennifer. Now at 83 years old, Victor still comes to the office, providing timeless input to the team. George joined the firm in 1984 and Jennifer in 1987, taking over the bulk of clients and workload.

For the past 35 years, I have been truly blessed to work side by side with my father and sister. I like learning about our clients, not just about their business or tax dynamics but also, about them personally. I like collaborating with my peers and other professionals. I am married to my best friend Nancy and we celebrate life each day with our two children.

I started working at George Herro, CPA in August of 2018.  Every day is FUN!  I meet people, get the opportunity to help them, and get to learn from and be a part of a family of people that are truly the best in the business.  I graduated from University of Wisconsin Milwaukee with a BBA in Accounting.  I became a licensed CPA in 1996.  When I am not here, my husband and two boys and I enjoy anything and everything OUTDOORS!
