Marta divides her time between mediating and litigating family law matters. Recently, through a Missouri Lawyer’s Weekly poll, she was voted by her peers as one of the “Best Divorce Attorneys in Missouri.” She was also elected by both her peers and Martindale-Hubbell to “The Bar Register of Preeminent Lawyers.”

Marta received her Juris Doctorate from the University of Houston and obtained a post-graduate certificate in Marriage and Family Therapy Training from the prestigious Menninger Psychiatric Institute. She has extensive training in negotiation and divorce mediation, and is a member of the Association for Conflict Resolution, the Association of Missouri Mediators, the International Association of Collaborative Professionals, and the Collaborative Family Law Association. Marta has taught Mediation, Dissolution of Marriage and Civil Litigation at Webster University and St. Louis Community College and is currently adjunct faculty at St. Louis University in the Graduate School of Social Work. She also conducts family law mediation training seminars for lawyers, judges, and mental health professionals, as well as seminars for individuals considering divorce. Marta has published numerous articles on family law and mediation, and as a regular guest speaker at conferences, on television and on radio programs, Marta has helped establish mediation and collaborative law as an alternative to divorce litigation in the St. Louis area. Marta was recently elected to “The Bar Register of Preeminent Lawyers” by Martindale-Hubbell and her peers. The Martindale-Hubbell Bar Register is limited to only the most distinguished law practices; those that have achieved the AV rating in the Martindale-Hubbell Law Directory. The “A” signifies the highest level of legal ability, while the “V” denotes “very high” adherence to the professional standards of conduct, ethics, reliability and diligence.
