Mars Insurance Agency was originally established back in 1968 with a very specific purpose in mind: to meet the needs of our valued insurance customers. We're located at 9 SE Virginia Road, Crystal Lake, IL. Our clients enjoyed the personal attention and professional service we provided, and it didnt take long before they started asking if we could handle all of their insurance needs. That was the beginning of who we are today, a full service independent insurance agency dedicated to becoming the one and only agent our clients will ever need. Feel free to call us (815) 459-0711
