Mary Thompson
Mary founded Thompson & Walker with a singular vision: to provide the same caliber of family law representation to everyday Missouri families that was previously available only to those who could afford downtown BigLaw rates.
A former law clerk to the Honorable Judge Patricia Williams of the St. Louis Circuit Court, Mary understands the family court system from the inside out. She uses that knowledge to anticipate every move and protect every client.
