Matthew Carroll is a registered Domestic Mediator with the Supreme Court of Indiana and the owner of Keystone Mediation in Dyer, Indiana. He works primarily in divorce and family matters, including parenting plans, child support, property division, post-decree issues, and prenuptial and postnuptial agreements. He also offers couples mediation for partners who are not ready for divorce and want structured support to address conflicts, identify areas of the relationship that are not working, and improve communication. He primarily serves clients throughout Indiana and in nearby communities in Illinois, including through Zoom.

He serves as adjunct faculty at Northwestern University’s School of Professional Studies in Chicago, Illinois, where he co-instructs the Divorce Mediation course with Sandra Crawford, JD. He also serves as adjunct faculty at Aurora University, introducing graduate students and emerging professionals to mediation skills and practice.

In addition to private mediation, Matthew designs and delivers training programs and mentorship for mediators and related professionals. Through Keystone Mediation, he developed an Advanced Divorce Mediation program and a six-part mediation skills workshop series focused on practical tools and communication strategies.

Matthew is a Certified Practitioner with the Academy of Professional Family Mediators and a registered Parenting Coordinator with the Supreme Court of Indiana. He is a member of the Association of Family and Conciliation Courts, the Academy of Professional Family Mediators, the American Bar Association, and the Lake County Bar Association in Indiana.

That background informs his approach to mediation through structured conversation, careful listening, and practical problem-solving.
