A graduate of Walla Walla High School in 1954 and a proud member of the Alpha Chi Omega sorority, Janet embraced life with enthusiasm. She was known for her creativity and passion for crafts, as well as her adventurous spirit, which led her to travel and create lasting memories with friends and family.
