Kathleen Barreto-Yamamoto
Resident of Pelham, NH
Beloved mother, sister, aunt, and dear friend, Kathleen passed away on April 19, 2012 after a courageous six month battle with cancer. She was 57. She is preceded in death by her husband and soul-mate Dr. Richard K. Yamamoto.
She was born Kathleen Anne Coogan to Germaine and Eugene Coogan in New London, Connecticut on September 5, 1954. Kathy grew up in Sunnyvale, CA and was a graduate of Sunnyvale High School and De Anza College of Cupertino CA. She had a daughter, Victoria, with her first husband Oscar Barreto. Following a divorce, she began a long, varied, and successful career in Silicon Valley. It was during this time that she met Richard and they eventually married. In 2005 she and Richard relocated to Pelham, New Hampshire anticipating a happy and long retirement together.
Kathy's great loves were children and family, particularly her daughter Vicky and nephew Francisco Agular. Along with her daughter, Kathy is survived by her sisters and brothers, Patricia Estrada, Dee Strait, Beanzie Coogan, Joseph (Patricia) Coogan, all of Sunnyvale CA, John (Elisabeth) Coogan of San Jose CA, her step-daughters, Cara Jean Yamamoto Donaghey of Pelham NH, Lani Yamamoto of Iceland and Sharon Yamamoto Takaki of Brazil.

A funeral mass was held for Kathy at St. Patricks Church in Pelham on Thursday April 26, 2012.
A memorial mass will be held on May 19 at 12:30 pm at St. Cyprian's Catholic Church, 195 Leota Ave, Sunnyvale, CA.

I worked with Kathy at TCI in Fremont CA during the late 1980s. We were technical writers, and I loved working with her, she was very good and really cool person. Kathy invited my wife Nancy and I to family celebrations at her parents. I have many dear memories of her, and am heartbroken to learn she passed so early. Big hugs to both families, my sincere condolences.

Our journey with all of you and Kathy through her long illness had our hearts and prayers in one place for the sole purpose of supporting her and leading her to wellness. Life has it's twists and turns, and no one is ever prepared for such a sad outcome, especially when she had done so well and worked so hard. Kathy was a special person who touched my life and I can only imagine how she inspired and endeared all of her siblings, children, stepchildren, nieces, nephews, ...She will be sorely missed, but she will always be remembered for the loving, spirited cousin I remember her to be. Our love, prayers and condolences to go you all.
