Thomas O. Sinclair

Thomas O. Sinclair is a Birmingham native who spent time at a military boarding school for high school before enlisting in the military when he was eighteen. After six years traveling the world, he gained an appreciation for furthering his education.


He enrolled at the University of Alabama and put himself through college in three years working two jobs. He went on to be recognized as the Most Outstanding Undergraduate in Finance and Economics, graduating with distinction in 1995.


Following graduation, he served as a loan officer in the finance industry before applying to attend law school. He was honored to receive the Harwell G. Davis Presidential Scholarship to attend Cumberland School of Law at Samford University, graduating in 1999.


Tom then went to work for a defense firm where he routinely represented automotive manufacturers and insurance companies. He served in a national counsel role in State and Federal Court, Multidistrict Litigation, and coordinated litigation in Arkansas, Florida, Georgia, Illinois, Kentucky, Louisiana, Mississippi, Missouri, Tennessee, Texas and West Virginia, and litigation arising from foreign venues. But he learned his passion wasn’t defending corporations, it was helping the people.


Tom now devotes 100% of his practice to representing individuals in litigation involving insurance and pension claims governed by ERISA and state laws and involving class actions. He has served as lead class counsel for tens of thousands in courthouses from New York to California.


Tom frequently is asked to speak at seminars for other attorneys and regularly contributes his time to public interest cases. He is the author of several articles on ERISA claims.
