Testimonials

Many of our clients have been with us for decades—a testament to our steadfast commitment to integrity and high-quality, highly personalized services.

Their work has always impressed me as extremely professional in addition to being timely and real world helpful. In the unique financial world of Delaware charter schools they are very well informed. I highly recommend Maillie to any organization looking for high quality auditing and financial consulting services.

Charles S. McDowell, Of Counsel, Potter Anderson & Corroon LLP

One time we needed Maillie to assist us in various aspects of a private university’s planned giving program. So I called Ed, and within a day we had a detailed response from Joe Shirley, outlining our specific needs and giving us direction. That information was invaluable to understanding that business, and we in turn earned the account.

John C. Sanchez, Logos Brokerage

Glenda and I have been using your firm for almost 38 years and we are always pleased with the quality of service and, obviously, the personal relationships we have garnered throughout the years.
