Tim is an accomplished trial attorney in the firm with over fifteen years of diverse litigation experience. His passion for trial work began during the early years of his career as an Assistant Prosecuting Attorney for St. Louis County. As a prosecutor, Tim gained a great deal of experience trying cases to both judges and juries. In the years following his service for St. Louis County, Tim has tried numerous cases on behalf of both plaintiffs and defendants in a wide variety of civil matters. Tim’s areas of focus at Rossiter & Boock are Estate and Trust Litigation and Commercial Litigation.

In addition to his trial work, Tim regularly advises businesses and individual clients to prevent legal difficulties, and, whenever possible, negotiates on their behalves to resolve disputes short of litigation.

Tim holds bachelor’s degrees in justice systems and psychology from Truman State University and a J.D. from the University of Missouri-Columbia. He is admitted to practice in the state courts of Missouri and Illinois, as well as the U.S. District Courts in eastern Missouri and southern Illinois. In recent years, Tim authored/co-authored two articles on Missouri estate and trust litigation, both of which were published in the St. Louis Bar Journal.

Tim lives in University City, Missouri with his wife and their four children. He enjoys spending time with his family, most of which is spent at any number of practices or games/meets around the area. Tim was recently appointed as the Provisional Judge for the University City Municipal Court. He has also served as the Chair of the Trial Section of the Bar Association of Metropolitan St. Louis, as President of the University City Swim Club, and as an adjunct professor at Lindenwood University in its graduate criminal justice program.
