I recently went back to work after retiring three years ago. I needed help setting up my own books and immediately thought of Denise, whom I have known for most of my life. She is honest, trustworthy and dependable.
After setting up my account on QuickBooks Online and walking me through the basics I decided to continue to work with her for monthly bookkeeping services. It was the best decision I ever made.
I highly recommend Denise for your bookkeeping needs.
