Peter Koller


Peter Koller joined CLA in June 2016 after 30 years as a litigation attorney with the law firm of Moss & Barnett, where he worked very closely with members of CLA's executive and risk management teams. Before his move to CLA, working with CPAs and their firms was the biggest part of Peter's law practice. That work included defending claims and lawsuits and advising CPAs and their firms on business, employment, and regulatory matters.

For a number of years, Peter provided a loss prevention hotline for AICPA members. That experience naturally morphed into providing those same types of services to regular clients. In addition to providing services to CPA clients, Peter volunteered his services to the Minnesota Society of Certified Public Accountants, writing amicus briefs in cases of particular interest to accountants and providing advice regarding various legislative initiatives.
