Mark was a true warrior who dedicated over 34 years of his life to protecting and serving others. Mark was a retired Supervisory Special Agent with the U.S. Drug Enforcement Administration (DEA), where he served with honor for more than two decades, in addition to 12 years as a local police officer. Months before he passed away from cancer, he was determined to run the 5K for Tunnel to Towers like he had for many previous years. He had chemo days before the run but pushed himself and completed his last 5K in Sept. of 2025.
