McMahon & Associates Certified Public Accountants, P.C.

Feb 2019

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
