Mac... AKA DJ On It... AKA Marcus... AKA BIG SEXY ;) Born and raised in Fort Collins, the folks of Northern Colorado are Mac's people! His upbringings come from the streets of north Fort Collins, the halls of Lincoln Middle School, the grounds of Poudre High School, and the rink at Rollerland. Mac got his first start behind the microphone at the age 15. Two turntables, with a mic and DJ On It was created, rocking out for 300+ teens every Friday night at Rollerland for 5+ years. DJ On It went on to DJ at the hottest bars and clubs in Fort Collins including the Drunken Monkey, 100 Octane, Suite 152, Tony's, Washington's, RecRoom, Luscious Nectar, Sports Exchange, Kong, and more! He also DJ'd at many High School Homecomings and Proms right here in NoCo! DJ On It took over NoCo's airwaves for the first time in March 2014 on 96.1 KISS FM for the Friday Night Kiss Mix. In September of 2015, DJ On It was asked to takeover the Midday Show on KISS and began going On Air as "Marcus". Later that year, Marcus became the night show host on 96.1 KISS and won BEST NIGHT SHOW by the Colorado Broadcasters Association and took 2nd place for BEST PERSONALITY. He can be spotted at the Budweiser Events Center filling in as the arena host, or just enjoying a night with his family cheering on the Colorado Eagles!

Currently, Marcus goes by "Mac" and hosts the Mac at Night Show on Big 97.9 from 7pm to 12am. Mac can also be heard on 96.1 KISS FM and 100.7 KOLT FM.

"It is truly a dream come true to be ON AIR every night on the same radio station I grew up listening to. I've got the best listeners anyone could ask for! Thank you for making Mac at Night Northern Colorado's #1 Night Show!" -Mac
