John Olson has always had a passion for finance and problem-solving, which made a career in mortgage lending a natural fit. His journey began with a senior-year internship at Wells Fargo, and over the past 24 years, he has built a distinguished career in the industry—starting as a credit manager and evolving into a leader of small and mid-sized mortgage lending organizations.

John holds a Bachelor’s degree in Business Administration and Marketing, with a minor in Management, from the University of Oklahoma. He has earned numerous sales honors throughout his career, including President’s Club recognition in both 2020 and 2021. From 2018 to 2022, John launched and led a builder mortgage joint venture, overseeing all sales and operations. Under his leadership, the venture grew to a 24-person team and funded nearly $1 billion in loan volume in under four years.

John is passionate about helping individuals and families create generational wealth through homeownership. Known for being highly available and responsive, he presents multiple financing solutions so clients can choose what works best for them. His professional philosophy is to always put your best foot forward and to learn as much from your setbacks as from your successes.

Outside of work, John enjoys spending time with his family, cooking, traveling, and watching college football. He is also deeply committed to community service and volunteerism.
