In parallel with his practice as an attorney, Michael has a passion for educating youth about law and democracy. He has facilitated mock trials and taught classes throughout the school year in every grade level on constitutional rights, the legal justice system, and the American Bill of Rights. This has always been important to him because he believes that a democracy depends on an educated public. Volunteering his time with youth is his way of teaching the next generation and making an impact. He has worked with judges, attorneys, police officers, and crime scene investigators to build crime scenes on school campuses for students to do forensic testing in science class, learn about what evidence is admissible in court and get exposure to all the pieces of the justice system.
