Our Team

The quality of the people within Harrington Group is one of our greatest strengths. Each of our professionals offers an informed perspective on developments in the nonprofit environment, as well as a proven ability to identify the right solutions for individual nonprofit organizations. As your strategic partner, we encourage you to look to us to address any challenges or opportunities that may arise. We are committed to responding to your needs. We also strive to create a relationship of respect and trust, taking care that all members of your organization feel supported by our efforts.

As outstanding professionals, our partners are often engaged to speak at conferences and seminars on topics such as financial management, cost allocations, and funding trends. Our knowledge and expertise is invaluable in helping clients improve their performance. To remain current on accounting and auditing matters related to the profession, and issues related to nonprofits, all staff, both licensed and non-licensed, are required to complete 80 hours of continuing education every two years. This internal requirement of Harrington Group is consistent with the requirements for licensure.
