Local Allstate Agent: Meet Mark Hartelius

I am a new business to the downtown Westmont area as of June and currently reside in nearby Downers Grove with my wife, Lauren. In my free time, I enjoy participating in local 5k races with my wife. Recently, we completed the Tough Mudder, Warrior Dash and Rock & Roll Half Marathon! When I am not participating in some kind of race challenge, you can find me enjoying a game of golf or rooting on my Chicago teams, Go Cubs Go! Fun Fact, I speak five different languages: English, Macedonian, Serbian, Croatian and Bulgarian!

Being involved in the community is very important to me. I am a proud supporter of the American Heart Association, American Cancer Society, National MS Society and the American Diabetes Association. I am looking to get more involved in the local Westmont non-profit organizations so I can help not only the community flourish, but also be a representative on behalf of the local community.

My favorite part about being an agent is being able to make a difference in someone’s household. Being in the insurance industry for 13 years, I’ve seen many families in unfortunate situations because they weren’t properly protected. My goal is to become the trusted Allstate agent to the people of Westmont and help their families be protected. We are located just a few blocks North of the Westmont train station downtown so stop in or give us a call today!
