Our Approach

At Professional Accounting Service, we provide added services by viewing traditional services, bookkeeping and tax return preparation, as the starting point for client services and not as the end product. In order to provide value services, we believe our firm must go beyond compiling the client’s monthly statements and tax returns. Recognizing the entrepreneurial risks and pressure faced by a successful client in today’s complicated and competitive business environment, our approach is to work the financial plan with the client throughout the year to minimize those pressures and risks.

Our Story

Forty years ago Professional Accounting Service was established and continues over the generations to serve the accounting, financial, business and personal income tax needs of the community. Our client base has grown over the years to include many of the children and grandchildren of those who came to our accounting practice in the beginning years. In 2022, ARCPA LLC joins forces with Professional Accounting Service and adds seasoned tax and accounting professionals to further provide specialized tax and accounting services to various individual and business clients. Many thousands have utilized our services and each year we welcome new clients that become part of our well satisfied and repetitive clientele.

Meet the Team

Our business approach is equally important as the tax and accounting experience we bring to each client, and because of our close working relationship with our clients, we are able to develop an in-depth knowledge of the client’s business activities, management philosophies and beliefs. The fact that we have long term business relationships with our clients is evidence we have been providing quality tax and accounting services for years.  We consider our clients to be our most valued assets. Our goal is to save you time and money with sound strategies that minimize your taxes and maximize your wealth.
