Thomas McDermott specializes in litigation, often representing employers and insurers in maritime matters. He also handles complex business disputes, employment claims and general litigation. Thomas represents professionals before state licensing boards, and in legal and accounting malpractice claims.
Since joining Lindsay Hart in 1976, Thomas accumulated more than 35 years of trial experience in federal and state courts and other administrative forums.
He also shines in the pro bono arena, sharing his legal talents by representing adoption reform advocates. He worked to uphold the landmark Measure 58, which allows adult adoptees to obtain their original birth certificates. He stuck with the case from the trial court to the U.S. Supreme Court.
“It was a civil rights issue,” he said. “More than 6,000 adoptees have accessed their original birth certificates, and there’s not been a single reported bad outcome.”
He is a member of the Oregon State Bar and U.S. District Court, District of Oregon. He is also a member of the Multnomah Bar Association, Maritime Law Association and Best Lawyers in America.
Thomas received his law degree from Hastings College of Law at University of California and clerked for the Honorable Frank K. Richardson, California Supreme Court. He is a graduate of Villanova University and served as a lieutenant in the U.S. Navy before law school.
Through his professional achievements Thomas was selected to appear on the Oregon Super Lawyers list in 2006.
We are passionate advocates for our clients. I work collaboratively with them, especially in the arena of professional licensing. State agencies have a lot of power to revoke a professional’s ability to earn a living, be it a physician, psychologist, chiropractor or optometrist.– Thomas McDermott
