Tom helped me with complex taxes. He patiently met with me over weekends and evenings, the only times I was free from work obligations repeatedly to have them completed. He was always on time and available and called IRS on several occasions on my behalf in front of me and in my absence to have questions answered. Very hard working. Thank you Tom!

For years, Tom O'Sullivan has been handling our incomes taxes, and we couldn't be happier. He takes great care in preparing and filing our taxes to ensure the highest quality of work.
He has gone out of his way to make sure we understand every aspect of the tax filing.
With his office in Concord, we found it had a professional atmosphere, which made us feel comfortable.
Tom's firm treats your tax return with respect, which is important to us. We trust him with handling our taxes, and wouldn't use anyone else.
