Our Association used Don O'Brien for our yearly audit in 2011. Don was always professional in dealing with myself, the accountant and other staff. He was in and out of our office in a timely and efficient manner. He had our audit completed by the date we had requested it be done. Overall, I was very pleased with the work that Don provided for us. Our organization will definitely engage him for all of our future auditing / accounting needs.

Don: We have been exceptionally pleased with your handling of our taxes last year. You were able to answer all our questions easi ly and in a way I especially could understand. We also appreciated the fact that you were able to accomodate our procrastination in such a timely manner. Thank you.

Don has taken over my personal and corporate account from Dexter Archibald who has retired. He has been professional and prompt in filing my corporate and personal returns. He's very approachable and offers sound advice in helping make informed decisions to maximize tax savings. I would recommend him unequivocally.

The New Beginnings Association hired the Don G. O’Brien Professional Corporation to prepare our year-end financial statements. We found Don O’Brien to be very efficient and pleasant to work with. He was available at our request, and helpful with various matters. We would strongly recommend this business for any audit needs, as we will definitely deal with them again.

I like working with Don O'Brien. He is a CPA but keeps his company small so I have direct access to him when I need to talk about a business accounting question, and he is the one who is working on my account. He does my business bookkeeping as well as my and my husband's personal tax returns. I'd recommend Don to anyone who doesn't like the big firms and wants immediate access to a CPA.
