Glenda was a proud graduate of Carthage College, where she obtained her Bachelor’s Degree, laying the foundation for her lifelong journey of learning and growth. Beyond her professional endeavors, her greatest joy came from spending time with her family—each moment cherished, each memory treasured.
An avid golfer, a passionate reader, and a talented writer, Glenda embraced life with enthusiasm. She found solace on the golf course, among the pages of a good book, or in the quiet reflection of her writing.
