Caroline Marks

Vice President, Co-Owner, Director of Operations-Marks Air, Inc. MACS Treasurer

Caroline grew up in this industry (literally—she’s been around this since she was in a playpen). At the beginning of 2000, she started as a full-time member of the Marks Air team, which is an A/C-only service shop that also distributes A/C parts worldwide. Before that, her experience concentrated on customer service and the customer experience. She currently serves on the advisory board for Erwin Technical College and the Diesel Program for Hillsborough Community College. She’s also a 609 proctor and have been serving on the MACS board for five years.

Caroline is a soccer mom of two teenage daughters and she loves exercise, yoga, Star Wars, Beastie Boys, good conversations, the beach, motivating others and learning. She’s also a history nerd and book worm. Pizza, red wine and guacamole are some of her major weaknesses (though not normally all at the same time). Out of all the things Caroline loves, smiling is her favorite.

Rob Bollinger

Part Owner-ABC Radiator

My name is Rob Bollinger, part owner and operator of A.B.C. Radiator and A/C located in Baltimore, Maryland. I have been working on automotive and heavy-duty A/C systems for over 20 years. A.B.C. Radiator and A/C is a family business which was started by my grandfather in 1970.

We provide the sales, service, and installation of all forms of transportation. Fun fact: we are the last place in Baltimore City to still repair are core radiators! We are the “best place in town to take a leak”. Coming from a family business gives me great pride in the work I do, and I am grateful for the relationships made over years with our customers and the local businesses.

Outside of the shop I am with my family… I have a beautiful wife and three amazing kids. In the morning while the family is still sleeping you can find me in the gym weightlifting. (It’s the best way to start the day!) In 2020 I was very happy to receive the young ambassador award at the training and convention show in Nashville. I hope to continue to be involved with the MACS organization for many years to come. Being a member has been a great asset to my company.
