Mari Vossen

Administrative Support

Mari joined Matter in 2006, and her smile has brightened our St. Louis office ever since. Having worked in administrative support at Washington University, she was initially responsible for all filing at Matter and quickly stepped up to help convert the firm to an electronic document management system. She also turns her diligence and eye for detail to facilitating check requests.

Mari has deep relationships with Matter families, and she loves greeting them on the phone and in person. She’s first in line to hold a baby when Matter clients and associates bring little ones by for a visit, and her thoughtful, caring nature is invaluable to our team.

A big Cardinals fan, Mari has seen countless games, which she believes has honed her skills as a team player. Despite her love for baseball, she readily admits that her four grandchildren will always be her favorite people to watch.
