A former Stoel Rives project finance partner has sued the firm in Washington, D.C., alleging it pushed him out because of his age, failed to give him proper credit for landing a major client matter and undermined his attempts to find a new professional home.

Roger Rosendahl, now listed as a partner at Nelson Mullins Riley & Scarborough’s New York office, lodged age discrimination and other allegations against his former firm. Rosendahl, representing himself, initially filed the Stoel Rives suit in December in D.C. superior court, but it was removed on Wednesday to D.C. federal court. Stoel Rives, an Am Law 200 firm based in Portland, Oregon, is being defended by Morgan, Lewis & Bockius.
