Our Team

Deborah Mininger


For the past 37 years, Deborah has been providing tax preparation services to  individuals and small businesses.

Establishing the business in 1980, Deb started as a home based business. In 1992, she expanded her successful tax practice to include financial services. Quickly she outgrew the space, and in 2000, she relocated to historical downtown Quakertown. She purchased and renovated an old Victorian building on Broad Street to accommodate her expanding practice. Today, her firm consists of three tax preparers and two office staff.

In addition to providing superior tax preparation service, Deborah offers her clients expert advice in retirement planning, educational planning and insurance. “I offer my clients a multi-faceted approach to address their growing financial needs.”

Deborah and her husband Henry enjoy DIY projects and traveling, but most of all, they enjoy spending time with their five children and six grandchildren.
