Trauner, Cohen & Thomas, a Sandy Springs, Ga., collections firm that operated for more than 30 years, has dissolved amid a whirlpool of litigation from former clients claiming that the firm failed to file suits on their behalf and used funds for those suits to pay its own expenses.

The State Bar of Georgia’s Web site shows that partner Robert Trauner has left for a solo practice, while Michael J. Cohen has relocated to the Peachtree Law Center in Atlanta, and former managing partner Russell S. Thomas is with the Creditors Law Group in Norcross, Ga.
