As your local State Farm Insurance Agent and a lifelong resident of the area, I’m proud to protect our community. I earned my B.S. in Fin. Planning and Business Management from the University of Illinois, where I was a pole vaulter for the track & field team. After graduation, I began my career with State Farm as a team member for another local agent. After learning everything I could about the insurance industry, I proudly opened the doors to my own agency here in Olney in November of 2018! My team has earned awards both company and industry wide by providing quality customer service and reliable insurance coverage – including State Farm Level Four Exotic Travel, State Farm Chairman’s Circle, State Farm SVP Club, State Farm Presidents Club and Million Dollar Round Table.

I enjoy staying active in the community and assisting with our area’s growth by showing support for other local small business owners. I’m a member of the Richland County Chamber of Commerce and enjoy getting together and networking with my peers. I also am a proud supporter of Olney High School academics and athletics. In my free time, I enjoy hanging out with my family and friends, playing golf, basketball and softball. I also spend time working on Frost Buddy, a universal can cooler company, with my brother.

My team of insurance professionals and I are excited for the opportunity to help customers with their insurance and financial services to help prepare them for life’s unexpected. We’re ready to help customers find the right policy for their auto insurance, homeowners insurance, renters insurance, life insurance, and more. We can also assist our Indiana and Pennsylvania neighbors! Click, call or come visit us at our Olney, IL State Farm Agency today.
