    Being both an excellent divorce attorney & a successful divorce mediator takes a certain type of person. Usually attorneys are not able to be effective mediators because our legal background and training conditioned us to give legal advice and to be our clients’ advocates. By contrast mediators are prohibited from giving legal advice & are required to be impartial. Marta is one of the exceptions because she is both a successful mediator as well as an excellent attorney. During mediation Marta is impartial yet compassionate, having the open mind necessary to communicate & negotiate between parties to assist them in reaching a voluntary agreement regarding their dispute. She uses her background in family therapy & extensive legal knowledge to assist her with mediations. Marta is also an excellent divorce attorney. Her 20 plus years of practicing in family law along with her dedication has aided her in being one of the best family law attorneys. I am happy to recommend her.

    I worked with Marta Papa on several different matters over the years. I consider Marta to be one of the stop family law lawyers in the St. Louis area. Marta is very thorough in her preparation and persuasive in achieving successful results for her clients. I strongly endorse Marta for family law and mediation skills.
