After graduating from law school, Mr. Keller clerked for the Honorable Morey L. Sear, United States District Judge for the Eastern District of Louisiana, from 1982 to 1983. He joined the Seattle law firm of Hillis Clark Martin & Peterson, where he became a partner and tried a number of complex commercial and product liability cases to successful verdicts.


Upon relocating to New York, Mr. Keller concentrated on corporate and securities litigation with the law firm Silverman, Harnes, Harnes, Prussin & Keller beginning in 1995, and continued to litigate shareholder derivative, corporate governance and securities cases after forming Harnes Keller in 1999.  In 2005, Mr. Keller became a New York partner in the Atlanta-based law firm Chitwood Harley Harnes (which had merged with Harnes Keller LLP). Throughout, Mr. Keller has been responsible for the litigation of a variety of complex consumer, corporate and securities cases in federal and state courts throughout the country. 


At Shahmoon Keller, Mr. Keller continues to pursue cases on behalf of investors and owners of businesses.  These cases range from claims to stop management interference with shareholders’ rights in connection with director elections to injunctive and damage actions to remedy unfair dealing or interference with the ownership interests of security holders.
