Hear From Our Clients
I highly recommend Ned O'Sullivan O'Sullivan Tax & Accounting for all your CPA needs. He did a great job on my year end taxes, and was very pleasant and easy to work with. After my accountant retired, I shopped around for a while and could not find anyone to take on my simple sub-S corporation's taxes. I was so happy to find Ned and am very happy with the results of his service.
