Jack Clifford Nieburger

February 8, 1936 – March 1, 2023 The Nieburger family is sad to announce the passing of Jack Clifford Nieburger, beloved husband, father, grandfather, and great grandfather, aged 87, of Moreno Valley, CA. He passed away peacefully at home surrounded by family. Born February 8, 1936, to Clifford Nieburger and Laura May (Betts) Nieburger, of Denver, Colorado, Jack attended Regis High School and Regis College in Denver, before later moving to St. Louis to attend St. Louis University Dental School. He graduated with his Doctor of Dental Surgery (DDS) degree in 1960, and held dental licenses in Missouri, Colorado, and California. While attending St. Louis University, Jack met the love of his life, Judith Ann (Wilhelmy) Nieburger, whom he married in 1960. The couple then began their life together in the then Sunnymead-Edgemont area of Southern California in 1960, where Jack was a Captain in the U.S. Air Force, assigned to March Air Force Base as a dentist from 1960-1962. Dr. Jack Nieburger – also known at the time as Dr. John Nieburger – opened his own private practice in 1963 as the first civilian dentist in Moreno Valley. Dr. Nieburger practiced dentistry in Moreno Valley for 37 years, where he was held in high regard by his colleagues and patients, before retiring in 2000. Jack was devoted to his late wife, children, grandchildren, and great grandchildren. His zest for life led him to explore the world through many camping, fishing, road trips, and vacations with his loved ones and close friends. Jack was also an avid collector of stamps, coins, and Star Wars memorabilia, but he was most passionate about geology. He loved collecting minerals and fossils from all over the world and was considered an authority on the history of Crestmore Quarry in Riverside, CA. His lifelong interest in minerals led to his participation in the Micro Mineral Society, Friends of Mineralogy, and to volunteering with the Jurupa Mountains Discovery Center and the San Bernardino County Museum. Jack also gave back to his community as a member of the Moreno Valley Noon Rotary Club, the Moreno Valley Friends of the Library, and the Moreno Valley Historical Society. Furthermore, Jack made generous donations from his personal mineral collection to the Jurupa Mountains Discovery Center (aka Jurupa Cultural Center) and to the Riverside Natural History Museum. Jack is survived by his son David Nieburger and daughter-in-law Yvonne Nieburger of Beaumont, CA; son Steven Nieburger of Moreno Valley, CA; and daughter Melissa Nieburger of Palm Desert, CA. He will also be greatly missed by six grandchildren, and four great-grandchildren. To honor Jack’s memory, a Memorial Service will be held at Miller Jones Mortuary, located at 23618 Sunnymead Blvd., Moreno Valley, CA, on Friday, March 31, 2023, at 10:00am, followed by a reception. The Nieburger family invites all who knew Jack to join us in reflecting on his incredible life.
