Jeffery Allen Mangera, born on 28 December 1949 in Oak Harbor, WA to Joseph Mangera and Gloria June (Toy) Mangera. Jeff’s parents and youngest sister, Joyce Adele Mangera preceded him in death. In his youth, Jeff lived in Hawaii; Jacksonville, Fl; Norfolk, VA; before moving to Sunnyvale, CA in 1959.
In 1968 Jeffery graduated from Luther Burbank High School, Sacramento, CA. He attended Sacramento City College, majoring in law-enforcement, prior to being drafted by the US Army. After his Army career he continued his education at San Francisco State University.
Sgt. Jeffery A. Mangera served in the 284th MP Co. at the Stockade, Long Binh, Vietnam 1971; D Co. 44th ENG BN Korea 1992; ENGR Co. Unit 07, Africa 1993. While being stationed at Fort Drum, NY, he served in Haiti and ended with his last station being at Ft. Dix, LA.
Jeff’s interests included Tai-Chi, Karate, mountain biking, photography, and traveling in Mexico, Europe, and Slovakia.
Jeff was a quiet man, with quick wit and sense of humor, enjoyed amusing pranks, especially on his sisters. He loved dogs and was always holding the family pet in photographs. In adulthood, he found dogs in need and gave them a loving home. Although Jeff had no children, he was a proud and loving uncle. He always brought special toys or education projects for his nephews and niece.
Jeff would travel from the Bay Area, to be at all family holidays and events. We all enjoyed the sweet bakery treats he’d add to the festivities.
He lived and worked many years in Santa Clara, CA as a self-employed owner of a pool and spa service.
Jeff passed away peacefully in his sleep of natural causes, in his home in Santa Cruz County, CA on 30 January 2022, aged 73 years 1 month and 2 days.
