Born on a Marine Corps base in North Carolina, Mark McKinnon was always an active child. A multi-sport athlete - including football, basketball, and cross country running - Mark still found the time to pursue the arts. Inspired by landing the lead role in his high school play, he turned down several football scholarships to attend Howard University in Washington, DC where he graduated with a BFA in Theatre Arts.
After graduating from Howard University in 2009, Mark frequently traveled between Washington, DC and New York City to establish his professional acting career. Mark is a proud member of SAG-AFTRA. He can be seen in his recurring role in "Blue Bloods" (CBS) as Officer Miller. He has booked co-star roles on several prime time network television shows such as "The Blacklist" (NBC), "Gotham" (FOX), and FBI (CBS) created by Dick Wolf. Mark is managed by Christopher D. Silveri, Founder of Center Stage Management theatrically represented by HCKR Agency, and commercially represented by WSM Talent Agency.
In 2012, Mark began coaching actors by teaching them on-camera technique and business strategies to build a successful acting career. In 2015, McKinnon Acting Studio, LLC was officially established. This studio was created to offer affordable acting classes, private coaching, and consultation for beginning and experienced actors in the Washington, DC area. His coaching has helped actors get in the best possible position to get called in for auditions and book work. Some of the actors at his studio have booked co-star, guest star, and recurring roles on several different network shows, films and commercials. Throughout the year, his acting studio also hosts industry workshops where he would have special guest Casting Directors, Talent Agents, and Talent Managers from New York to teach on different topics.
