I wanted to let you know how much I appreciate the way you and your firm have taken charge of our Accounting issues, questions and concerns. I have been in business for some 10 plus years and have had 3 accountants and until now did not feel like anyone was listening. I also appreciate that you will explain the numbers to me since I am not of the accounting type. Thank you and I look forward to working with you long into the future.
