“Just want to let everyone know that we were able to secure the government loan and a grant that will allow us to continue working from home and to quarantine as much as possible. It is still important for us to do everything we are currently doing. This is largely in part to our ability to respond to the grant and loan application process in such a timely manner because of the incredible help of our accountants E.J. Callahan CPA. They did not allow us to miss the opportunity and we secured the resources needed to weather the storm. 

Although life will probably be challenging for a while at home and at work, we are going to come out of this stronger bc of what everyone is doing now. In short, we are surprisingly in great shape and I am certain we will survive. When you see them walk in the office next time, make sure you let them know you know who they are and how their company helped all of us.”

“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 have stuck with him and his company for over 25 years. Much more than accountants, much more than auditors, E. J. Callahan & Associates are real business and tax consultants. They have helped us to grow from a $10mm a year contractor to a multi-billion-dollar company.”

“Ed Callahan and his firm have been the trusted CPA for Vantage Builders for years. They are not only trusted consultants for us, but always make sure to be truthful rather than just telling us what we think we’d like to hear. We appreciate that the team is consistently accessible and always makes us feel like a priority. Assessments are extremely thorough which never fails to leave us confident with the professional advice given when assisting us in making very important decisions that directly affect our company as a whole.”

“I have worked with E.J. 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 third-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.

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