Helping business owners manage their finances for 25+ years.

While there are many experienced and fully qualified Accounting Firms, Financial Management Companies, and Executive Coaching Services to choose from, we believe that R. Tisi Professional Corporation offers a unique value that many large firms may overlook: the value of relationships. 

Founded in 1996 by Ray Tisi, our business has evolved from a bookkeeping and accounting firm into a company that offers complete business and financial management services designed to help your business gain the success you desire.

Our Clients Are Our Partners

We view every client relationship like a partnership, and truly believe that our success is a result of your success.

We are committed to providing close, personal attention to our clients. We take pride in giving you the assurance that the assistance you receive comes from years of advanced training, technical experience and financial expertise.  Our continual investment of time and resources in continuing our professional education, state‐of‐the‐art computer technology and extensive business relationships is indicative of our commitment to excellence. 

Our dedication is to provide superior client service and, as we have from the day we opened our doors, we endeavor to continue to provide the highest quality professional guidance to each of our clients.
