My name is Jonathan Medina, owner of Medina Mufflers Automotive. As a Veteran-owned and operated shop, we’re built on discipline, honesty, and real transparency. When you visit any of our three locations in Arlington Heights, Mount Prospect, or Crystal Lake, you’ll get a no-guesswork visual inspection, clear explanations, and recommendations you can trust—because the owner is still under the cars, making sure the job is done right.
