Mark was raised on the mean streets of Torrington, Connecticut. He graduated from Torrington High School in 1991 and Marist College in 1996 with a degree in Communications.

He was hired by WSB Radio in 1997 as a part-time traffic producer. Mark eventually moved to on-air traffic reporting for both WSB Radio and WSB-TV. 

Mark became the fulltime traffic anchor for WSB-TV in 2002. He retired from his Emmy winning television job in August of 2022. 

Mark’s roles with WSB Radio expanded through the 2000’s. He was tabbed to host the pre and post-game shows for the Atlanta Braves radio network and the Atlanta Hawks radio network.

He began hosting a weekend sports talk show in 2001. In 2005 the show changed from a sports talk show to a general talk show. He continued with that program until 2014 when he was given a nightly talk show heard from 10pm-midnight. Mark and the Bananas raised the ratings from 10-midnight from 17th place in the market, to second place. 
After the success of the show from 10-midnight, the crew was moved to 7-9pm, then 6-8pm. In early 2020 he took over afternoon drive (4-7pm) on WSB Radio. The show is consistently number one in the time slot, and often the most listened to radio show in Atlanta.

Mark is married to Dr. Maya Arum and they live on the west side of Atlanta with their two dogs, Deuce and Soba.
