Meet Mark Gundersen

Your Trusted Mortgage Expert in Thornwood

Mark Gundersen and his wife, Rachel, first crossed paths at Western Illinois University. Since 2003, they’ve embraced life in the Fox Valley area and made Thornwood their home in the summer of 2015. Together, they’re raising a freshman, an 8th grader, and a 5th grader, enjoying the unique journey of parenthood. While Mark’s coaching days are behind him, he now supports his children as they grow as athletes and individuals, cheering them on from the sidelines. When he’s not attending their games, Mark loves spending time with family at Castle Rock Lake in Wisconsin, going to concerts and sporting events, and gathering with friends and loved ones. He also enjoys smoking meat and cooking on his Blackstone. He pretty much uses it for anything. He savors the idea of serving a smoked brisket to his neighbors and friends or making breakfast for the kids and their friends.

Professionally, Mark is a dedicated Branch Manager and Senior Loan Officer with Mutual of Omaha Mortgage in St. Charles, offering a full range of home loan products to meet diverse needs. Whether you're a first-time homebuyer looking for down payment assistance, a homeowner exploring refinancing options, or an investor seeking specialized loan products, Mark has you covered. Mutual of Omaha Mortgage’s offerings include conventional loans with flexible terms, FHA, VA, and USDA loans, home equity lines of credit, and reverse mortgages.

Mark’s personalized approach sets him apart. He takes the time to understand each client’s financial situation, tailoring mortgage solutions that align with their goals rather than adopting a one-size-fits-all method. Through clear and transparent communication, he demystifies the mortgage process, making it approachable and stress-free. From explaining loan options to guiding clients through every step, Mark ensures you feel confident and supported. His commitment to building lasting relationships extends well beyond closing, with ongoing post-purchase support, refinancing consultations, and future home loan guidance.
