About Us

Our Mission at Maillie LLP is to provide exceptional client services with pride and integrity. We strive to exceed expectations and are passionate about the success of our clients, business partners and associates.

Serving Clients Since 1946

Maillie LLP is a firm that combines a depth of expertise with a commitment to forward thinking.

In 2021, Inside Public Accounting once again named Maillie one of the “Top 300” firms in America. Today, we continue to grow, leveraging our seven decades of experience to help our clients achieve success.

Steady Growth and Expansion

Our organization has followed a steady path to expansion in size and capability. Since 1946, we have grown and succeeded through solid management practices, ongoing expansion of accounting and business expertise, exceptional client service and the wisdom to identify and pursue new business opportunities.

An Exceptional Professional Staff

When you work with Maillie LLP, you connect with a team of more than 100 highly respected, and deeply experienced, accounting and business professionals. All of our partners and principals and most of our professional staff are CPAs (certified public accountants). Our team includes financial service generalists, audit, accounting and technical specialists, full-time tax and deferred compensation professionals, management information systems (MIS) experts and human resources consultants.

Affiliated Companies

To assure our ability to provide comprehensive services to our clients, Maillie LLP has established affiliated companies specializing in the areas of financial planning and municipal consulting services.


Maillie has a 70 year tradition for delivering high quality and highly personalized services.
The fact that many of our clients have been with us for decades is a testament to our steadfast commitment to this principle.

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.

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.

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.
