Diane D. Gross


February 5, 1952 - December 7, 2023

Diane D. Gross, 71, of Hot Springs, S.D., passed away at her home on December 7, 2023, surrounded by her husband, Rich and son, Sean.

Diane was born on February 5, 1952, at Sampson Air Force Base in New York, welcomed by her loving parents, Lucille (nee Hennessey) and William (Bill) Muscarella. Diane was the oldest of five Muscarella children and growing up in an Air Force family gave her the opportunity to live in many locations in the States as well as Japan and Germany. Her childhood also gave her both a lifelong passion for veterans as well as a sense of adventure. That sense of adventure led her eventually to Laramie, Wyoming, where she attended the University of Wyoming. While there she met and married Bill Sullivan.  That union resulted in the birth of her two sons, Sean, and Paul Sullivan. She later met and married Karl Nordman and became a stepmother to his many children.

After receiving both her bachelor’s and master’s degrees from UW, she worked for the university in the field of extended studies while working on her Ph.D. from Colorado State University. Eventually she and the boys relocated to Ormond Beach, Florida where she worked as an administrator in distance learning for Daytona Beach Community College. While attending a distance learning conference in Miami she met the love of her life, Rich Gross. They were married a year later, a marriage that lasted nearly 30 years.

After a stint in Cedar Rapids, Iowa, where Diane was involved in many volunteer activities as well as a partner in their distance learning consulting firm, Rich and Diane relocated to what became their earthly spiritual home, Hot Springs, South Dakota.  In 2000, Rich and Diane opened Black Hills Books and Treasures, which Diane ran for almost 19 years. After retiring from the store, she then worked as Development Director for the Mammoth Site, as well as co-owner and partner in their consulting firm, RichGrossSolutions. As a consultant, Diane had the opportunity to visit numerous colleges around the country.

Diane was a friend to everyone she met as well as a constant volunteer. Her favorite volunteer activities included Rotary, the Cultural Development Organization, and her special love, the American Legion Auxiliary. Her love for her husband, her two boys and grandchildren, and her volunteer spirit, was only exceeded by her deep faith and love of the Lord.

Diane was preceded in death by her father, Bill. She is survived by her husband, Rich; mother, Lucille Muscarella of Seminole, Fla.; sons, Sean Sullivan of Las Vegas, Nev., and Paul Sullivan of Ormond Beach, Fla. She is also survived by her sisters, Carol Edman, of Sanford, Fla., Jean Chance of Gainesville, Fla., and Ann-Marie Barnard of Celina Texas; and brother, Tom Muscarella of Seminole Fla. She was also proud of her grandchildren, Sydney, Rhett, Cannon, Aiden, and Paris.  She also leaves behind aunts, uncles, and dozens of nieces, nephews, cousins, and other extended family members.
