Fifteen years ago, Minneapolis law firm Dorsey & Whitney launched a legal aid clinic with two nonprofits and what was considered an unusual additional partner at the time — the in-house legal department of U.S. Bancorp.

Today, the company’s pro bono program is involved with no less than 15 legal aid organizations and legal aid clinics. More than half of its 94 attorneys in the United States and its paralegals volunteer time. And the bank continues to expand its pro bono footprint.
