Mark Haefner was born and raised in St. Louis, Missouri. After high school, Mark attended the University of Missouri - Kansas City (UMKC) where he earned a Bachelor of Arts in Administration of Justice.

Upon graduating from UMKC, Mark began working at the Missouri Division of Family Services. He investigated child abuse and neglect. He later transferred to the Alternative Care Unit and worked with children in foster care.

Mark's goal for each foster child was to find that him/her a home. During his time with DFS, many children were adopted, reunified with their parents, or ensured they had the skills for independent living.

Mark grew frustrated with the lack of progress in the court system, due in large part to certain attorneys not working as hard as he did to protect children. He then decided to go to law school. Mark returned to the University of Missouri - Kansas City and began work on earning his law degree. While there, he met many colleagues that shared his passion and frustration with the legal system.

Post graduation, Mark became an expert in legal issues involving children. Divorce, child custody, child support, protection orders, paternity, and Motions to Modify became Mark's area of expertise.
