His legal expertise spans the entire spectrum of school law, where he passionately represents students, teachers, faculty, and administrators.

Throughout his career, Mark has demonstrated a commitment to staying at the forefront of education-related issues. He has authored and spoken extensively on a diverse range of topics, including but not limited to Title IX, FERPA, state student privacy laws, high school athletic eligibility, special education rights and responsibilities, IDEA, state operating standards, suspension and expulsion rights for students, college codes of conduct and academic misconduct, public record laws, FMLA, sovereign and qualified immunity, school dress codes, student civil and constitutional rights, and schoolhouse sexual assault.
