Dale F Oser CPA
We started this CPA firm in 1980 with the idea of giving every client professional and personal service at an affordable rate. We've stood the test of time since our humble beginnings, having helped clients with their tax and bookkeeping needs for three decades and the better half of a fourth. We have experience with IRS and Louisiana tax audits.

We have a certified QuickBooks ProAdvisor(R) on staff, which means we can install the QuickBooks(R) accounting program on your computer, set up your chart of accounts, train you in the use of the program, and give you technical support. We also provide a bookkeeping service should you not have the time or personnel to do your own bookkeeping.

I moved to Mandeville, Louisiana, from New Orleans, Louisiana, in 1980 and opened my accounting practice that same year. It was the first accounting firm in Mandeville and remains the oldest in operation. Over the years, other firms have popped up, but our knowledge, customer service and experience have allowed us to stand the test of time.
Tax season is a time of year that many people, both business owners and individuals, dread. Preparing your own tax returns can be confusing and frustrating, but with the right help, it does not have to be. Dale F. Oser, CPA, is and has been a reliable and reputable source for tax preparation, advice and assistance in Mandeville, Louisiana, for over 40 years.

Dale has been doing my taxes for over twenty years, he is extremely good at tax preparation and investing advice. I wouldn't want anyone else doing my taxes, he is the best! I can't thank him enough for helping my wife and I navigate all the tax changes over the years.
