OAA brings to bear more than three decades of bookkeeping experience, with experience including office, retail, hospitality, and non-profit books. Accuracy is so important, but timeliness has a lot to do with the work. Deadlines are as vital to our success as the drive to get the books in balance.

"There's a lot of satisfaction in getting things to balance. I know it's important to a client's financial stability, but it's also personally rewarding for me to have the numbers work the way they're supposed to in a format that's usable for that
business owner."
