Geraldine Antonetta Rentz

November 21, 1941 ~ March 20, 2024 (age 82) 82 Years Old




Geraldine (Geri) Antonetta Rentz, 82, of Walnut Creek, CA passed away in her Rossmoor home on March 20, 2024.  Geri was predeceased by her parents Raymond Rentz and Concetta Nacovanni Rentz, and her brother, Karl Karbens.  Geri is survived by her beloved sister, Diana Rentz and cousins, Valerie Kosinski and Ken Travis. 

Geri was born in Chicago, Illinois, on November 21, 1941.  Her father died when Geri was five years old and the family moved to southern California.  She attended Rosemead High School and graduated at the young age of 16.  She immediately took a job with the family firm of Casner Construction.  The family quickly realized her potential and when their matriarch was ready to retire, Geri was promoted to manager of operations.  She valued all the experiences she had with them and continued to use that knowledge thru the remainder of her career.  She later went to work with Wells Fargo Bank where she quickly demonstrated her knowledge, skills and perseverance, and was ultimately promoted to Associate Vice President.  She moved to northern California to enjoy her retirement. 

Geri enjoyed sports, travel, reading, movies, bridge and anything that gave her mind a challenge.  She was known for enjoying quizzes as a child, could name every old movie and its actors, as well as most books and their authors.  She was raised as a Catholic, and as she got older decided to read the Bible cover to cover and loved it.  She joined bible studies, and a member of Grace invited her to join the Grace Presbyterian bible study.  She later joined Grace Presbyterian Church of Walnut Creek in 2012 and quickly became a beloved member.  She served as Elder, Clerk of Session, head of Pastor Search Committee, Moderator of Presbyterian Women, and Assistant Treasurer.  She founded Grace Book Club and Bridge Club and was always up for a challenge….the more the better for Geri. 

Geri was a generous soul.  If she saw a need, she took action.  She provided heaters, copiers, microwaves and even her car to those in need.  She also served as mentor to so many over her life which gave them confidence in their abilities.  Geri had a great sense of humor and used it often, as well as a fast temper which was quickly gone and she attributed to her Italian heritage!  She was a true servant to so many…..her presence, friendship, generosity and tireless work will always be remembered.  Geri will be greatly missed by all who knew her.

A celebration of Geri’s life will be held at Grace Presbyterian Church in the coming months.  The internment of her ashes will take place at Oakmont Memorial Park in Lafayette.
