“When I started JMA thirty + years ago I went through three outside accounting firms in the first two years. No one understood my business. Then I met Ed Callahan and stuck with him for 25+ years. Much more than an accountant, much more than an auditor, a real business and tax consultant that has helped us grow from a 10mm /year contractor to a multi-billion dollar company.”

President, John Moriarty & Associates

“Ed Callahan has been the trusted CPA for Vantage Builders for years. Not only is he a trusted company consultant for us, but he always makes sure to be truthful rather than just telling us what he thinks we’d like to hear. We appreciate that he is consistently accessible and always makes us feel like a priority. His assessments are extremely thorough which never fails to leave us confident with the professional advice he gives when assisting us in making very important decisions that directly affect our company as a whole.”

Ed Silva

“I have used Ed Callahan for all our business and personal tax accounting as well as estate planning for our multimillion dollar businesses for over 30+ years. As a 3rd generation, family owned and operated business, Ed has been instrumental in mentoring me over the years professionally and personally through generational transition for which I am forever grateful to him.

I would recommend E.J. Callahan and Associates to anyone looking for a professional who will help you build a lasting relationship while managing your financial success by looking out for your business and personal assets.”
