Casey joined the Sumner Insurance Services team in 2020 after having worked professionally with Caleb since 2017. She spends her days overseeing the operational, marketing, and public relations aspects of Sumner Insurance Services. Casey’s day often shifts from one task to another in financial management, marketing, communication/outreach, personnel and HR, or data analytics.  

​

Having earned her MBA in Health Services Administration as well as Finance, she has enjoyed 30+ years working across various business management disciplines and healthcare delivery systems. She recognizes that a valuable, multi-faceted approach to business management is vital. Having contributed in different key roles, she knows the sum of the parts truly relates to the value of a unit as a whole. She loves that on any given day her tasks transition from crunching numbers, overseeing product marketing campaigns, to cultivating a positive culture within the team. Casey loves the “soft” business part of her role related to employee development and empowerment. Helping others unlock their own potential is a great gift to both the individual and the agency. She wants her employees to truly “find their joy” in their work because ultimately everyone wins!

​

Casey Sumner actively serves on the Central Missouri Loop Board, the Central Bank Advisory Board of Directors, the Whiteman Air Force Base Community Council (BCC) Board of Directors, as well as the Sedalia Chamber of Commerce Military Affairs Committee which supports both the 509th Security and Maintenance Squadrons for Whiteman Air Force Base.  Casey volunteers as the Applewood Christian School High School Student Council Advisor. Formerly, Casey was an active member of the Friends of Arrow Rock Board,  the Experience Arrow Rock Board, and former Executive Board Vice President of Membership for the Sedalia Area Chamber of Commerce.

When Casey is not in the office, you will often find her immersing herself in the various communities she serves and supports, at the family lake camp, or on the farm she shares with Caleb and their four children, Matthew, Madeline, Molly, and Mia. Casey loves overcast days with candles lit all around the house! She loves to RV camp around Missouri and surrounding states but her heart knows that the Adirondack Mountains of upstate NY (where she grew up) remains her most favored mountain/lake retreat. Road trips with Caleb and her kids are her thing! Whether paved or dirt, she loves to explore the roads of America. She has joyfully criss-crossed the United States many times over and absolutely loves to immerse herself in getting to know community folks and to study various architectural design elements along the way. She is a sentimentalist and loves small, quaint towns. Having grown up on the east coast with the story of America’s beginning all around her, she loves the nostalgia, the mystery, and the story each place begs to tell.
