Maureen Ann Richards Kostalnick passed away on Friday, Feb. 21, 2020.

Maureen was born in Avon, Ohio, and graduated from Avon High School. Her life was dedicated to her family and to the children she worked with as a sign-language interpreter.

Maureen was also the author of “The Butternut Tree.” Based on Maureen’s life, the novel deals with a young woman (Maureen), her mother and secret that caused the community to shun her family. She also co-authored a children’s book, “Maureen and Billy, the Bad Kids,” with her son, Dr. Daniel Jon Kostalnick. She began her writing career as a humorist for the American Greetings Corporation in Cleveland.

Maureen is survived by her loving husband and high school sweetheart, Chuck; her children, Kathleen Antrim of Pleasanton; Charles Kostalnick II (Kay) of Castle Rock, Colorado; and Daniel (Suzanne) of Pleasanton; and her grandchildren, Kaitlin Antrim Laines of San Francisco, Taylor Antrim of Lone Tree, Colorado, Charles Kostalnick III of San Francisco, Michael Kostalnick of Livermore, Elizabeth Kostalnick of Pleasanton, Madeleine Kostalnick of Pleasanton, and Danielle Kostalnick of Pleasanton. She is also survived by her sister, Donna Wachholz, of Avon, Ohio.

A memorial service and a celebration of life reception was held for Maureen on Thursday, February 27, at St. Augustine Catholic Church in Pleasanton, and Campo di Bocce in Livermore.
