Community Service

We’re not just lawyers—we’re also Oregonians. We love the beauty of the Pacific Northwest and the lifestyle it offers, and we do our part to protect both through community service.

Our History & Timeline

A law firm that’s been serving clients for more than 85 years must be doing something right. Our firm’s history is deeply intertwined with the history of our region. Cosgrave Vergeer Kester LLP traces its roots in Portland back to 1934, when the law partnership of Maguire & Shields was formed during the Great Depression. Our founders’ complementary styles made them a perfect team. Outgoing and expressive, Robert Maguire brought a charismatic presence to the courtroom. Roy Shields had a modest, self-effacing style, and when arguing a case relied on calm, logical presentation. Their office was in the Pittock Block, at SW 10th and Washington streets, where it remained for the next fifty years. Maguire had a distinguished career in public service—a tradition that continues at Cosgrave to this day. Before going into private practice, he was Assistant U.S. Attorney for Oregon and Chief Deputy District Attorney for Multnomah County. For many years, he acted as a Master in Chancery and Special Master to the U.S. District Court for Oregon. From 1947-49, Maguire was honored to serve as a judge of the historic War Crime Trials in Nuremberg, Germany. Shields was an Assistant Attorney General for Oregon, then local attorney for the U.S. Railroad Administration in Salem. He moved to Portland as Assistant General Solicitor at Union Pacific Railroad and rose to General Solicitor, a position he held until 1958. Shields oversaw all the railroad’s trial work in Oregon, as well as contracts, real estate, administrative, and legislative matters. His close ties to the railroad industry are another long-standing tradition at Cosgrave. We still serve many railroads, trucking companies, and other transportation clients, and our lawyers are leaders in industry associations. Over the decades, our team of talented attorneys has grown, as has the scope of our practice. Cosgrave is made up of people with diverse skills and experience, serving diverse industries. Today, we provide a wide range of business and litigation services to clients based in the Pacific Northwest, as well as clients with national and international operations.
