    Boris & Jill Gunjevic

    Owner & Operator

    Boris and Jill Gunjevic own and operate Christian Brothers Automotive (CBA) in West Chicago, providing quality automotive repair services with honesty and integrity. An early childhood passion drew Boris towards the automobile business starting in high school at local car dealerships. He earned a degree in Automotive Technology from Southern Illinois University and spent nearly two decades working as a corporate field manager in the automotive business. Jill brings a diverse background to her ownership role. She is a graduate of Bradley University with degrees in Psychology and Forensic Science. Yes, her early career involved working with DNA evidence for the Illinois State Police, but their role in the local community sparked Jill’s love of non-profit service where she later worked before transitioning to full-time mommy of two. Jill shines in her ability to build meaningful connections with those around her. After enduring multiple cross country moves for his career, Boris discovered this exciting opportunity to open the first CBA location in Illinois where he and Jill could establish permanent roots in their hometown Chicago-metro area. They are inspired by CBA’s faith-based approach to ethical car-care and genuine interest in helping people, but not just with automotive needs. Boris and Jill will utilize their shop resources and business relationships to serve fellow community members though local charitable organizations. Please stop in to meet the Gunjevics and discover the “nice difference” at Christian Brothers Automotive!

David M.


Our service manager David entered the auto industry 39 years ago when he started working at his family’s tire and repair business in Chicago. Since his two adult children have moved out on their own David has acquired a few cats to keep him company and reduce the chipmunk population in his backyard! David spends his free time kayaking, working out and tending to his lush vegetable garden. Although he is a “healthy” eater, David can occasionally be tempted by Jimmy Johns and fine dark chocolates.

Ralph A.


Ralph has been in the automobile and motorcycle repair business for 25 years. He entered the industry as an owner of both an auto detailing and transportation business with his brother in the Chicago area. Whether it has four wheels or only two, Ralph can repair it! When not spending time with his two younger boys, Ralph works on and drag races his 600+ HP motorcycle. Ralph has worked on high end luxury and exotic vehicles and enjoys tuning one of his many German automobiles. His favorite food is BBQ and weaknesses are Coke and Reese’s Peanut Butter Cups.

Mike M.

undefinedMike has been in the automotive service industry for over 30 years. He started out performing mechanical repairs related to vehicle collisions and grew to become an advanced diagnostician. He currently possesses an ASE Master and L1 Advanced certification status. When not at work he spends time with his wife and three daughters, building websites, or day dreaming about racing in the NASCAR series! Mike’s tool chest is larger than some loft apartments in New York City and contains enough computing power to launch a rocket…or diagnose your Check Engine Light!!

Adam C.

undefinedOur service consultant, Adam, attended Southern Illinois University’s automotive program and spent over 30 years as a technician and manager. For the past 13 years he has operated his own auto repair business. He successfully grew his business through excellent customer service and word-of-mouth recommendations.
