Dedicated to the defense of health professionals.

Robert J. Andretz

Senior Attorney

Rob Andretz is passionate about helping his clients. He has had the honor and privilege of being licensed to practice law since 2003, and he is happy to put his education and experience in law, biology and psychology to work for his clients.

Before joining Chapman Law Group, Rob defended clients charged with drunk driving or drugged driving in Michigan district and circuit courts in more than 40 counties across the state, taking many of those cases to trial. Among those clients, Rob represented many doctors, nurses, and other licensed healthcare professionals charged with drunk driving and understood the importance of counseling them on both the legal and collateral consequences of a criminal conviction.

Rob also practiced as a solo attorney in East Lansing, serving his clients primarily in the areas of criminal defense and family law. As a trained mediator, Rob volunteered his time as a civil mediator and a domestic relations mediator. He also worked for two years at the Third Circuit Court in Detroit as a Research Law Clerk, researching and drafting proposed opinions for circuit court judges on topics ranging from antitrust to zoning.

Rob thoroughly enjoyed law school and graduated cum laude from the Thomas M. Cooley Law School in 2003 with concentrations in litigation and international law. While in law school, he honed his editing skills by serving as the Casenotes Editor on the Board of Editors of the Thomas M. Cooley Law Review and studied abroad in Australia and New Zealand. As a law student, he earned Certificates of Merit in Trial Workshop, International Law, and Immigration Law, and he was honored as a finalist in the State of Michigan Moot Court Competition in Detroit and a quarter-finalist in the National Criminal Procedure Moot Court Tournament in San Diego. Rob was also a Prehearing Extern at the Michigan Court of Appeals while in law school.

Prior to law school, Rob double-majored at Hope College in Holland, Michigan, and earned a B.S. in biology and a B.A. in psychology. During college, he conducted social psychology research and conducted tropical rainforest ecology research in Costa Rica. Rob also volunteered his time as a Big Brother for Big Brothers Big Sisters.

Rob and his wonderful wife, Jacqui, are the proud parents of two daughters and two sons. In his free time, Rob serves as the Vice President of the Clinton County Bar Association, the Deputy Grand Knight of Knights of Columbus Council 11694, and a Den Leader for Cub Scout Pack 572. He previously served on the Victor Township Planning Commission, served as President of the Catholic Lawyers Guild of the Diocese of Lansing, and served as Chair of the Greater Lansing Catholic Education Foundation.
