Mark moved away to college, graduated, became a first grade teacher and started getting on stage. He left teaching and now his time is primarily devoted to stand up, writing, producing screenplays and kicking ass. His fans can catch him on Adam Devine's House Party on Comedy Central, AXS Gotham Comedy Live and various podcasts... some of which can be found under the 'Media' section of this very website. Mark has done 6 tours for the troops and broken two arms while playing basketball. He can also be seen regularly at The Hollywood Improv, Comedy Store and Laugh Factory.
