I've been working with Terry, Jackie, and Olivia so far so good. We bicker about accounting - but they know their stuff in the end. Good accounting ain't cheap!

I have been a client for over 20 years and McMahon has always served my business with care, attention and the latest in knowledge and technology.

When my accountant passed away over a decade ago, McMahon and Associates took over much of the practice. That have been marvelous treating me with respect and Personal attention. Now that I have closed my business, I just file individual returns. The firm makes it easy for me even though I live in Illinois and do not have a car. I am most appreciative of the service they provide and give them my 100% endorsement.

I truly would not know what I would have done without the help of McMahon and associates. They are extremely compassionate, caring, and by far the best accounting firm in the business. Karen McMahon is so easy and wonderful to work with and the payroll department is exceptional! I lost my accountant of 20 years suddenly in April. They helped me pick up all the pieces and finish out the year seamlessly for both my business and personally. I would highly recommend this accounting firm to each and person or business I know.

As an owner of a midsized HVAC business with nearly 70 years in the business we've experienced more than our share of accounting firms. That was until we happened upon the services of McMahon & Associates. We could not ask for a more professional, thorough, fair, and as a bonus, more friendly firm. They have always been extremely quick in responding to every request. It has truly been comforting knowing they're in our corner when challenges arise. We wouldn't think of looking anywhere else. Karen McMahon especially has proven time and time again to be an invaluable ally for our company. Don Kovacik

We have been doing business with McMahon and Associates for the last 5 years, in all those years we never met Karen McMahon up until two weeks ago. We requested to have a meeting so that we can discuss our tax returns, today we received a bill in the amount of $450.00 for meeting with Karen McMahon and one of her employees. We were never made aware that there was a charge for meeting with them, and on top of that the meeting lasted approximately 30 minutes, not even top paid attorneys charge that kind of fees. When you try to call them they do not return your calls. Karen McMahon being the owner of such a large accounting firm is not very customer oriented, when we tried to talk to her and we told her that we will probably move our business to another accounting firm she in so many words told us that she did not care. That is no way to treat your clients. We would definitely NOT recommend McMahon and Associates Company for personal or business use.
