Colleen Harrigan Brennan

January 9, 1932 - August 30, 2025

Colleen passed away at the age of 93. She was born in Pasadena (she enjoyed telling people about how it snowed that day in Pasadena!), and was a lifelong Californian, growing up in Highland Park and later living in Glendora, Alhambra, and Arcadia. She resided in Arcadia at the time of her passing.

Colleen was the daughter of Frank and Marie Kaa Harrigan. She married Robert Brennan, Jr and, today is survived by her son Robert F Brennan III and his wife Mary Alice.

Colleen was a primary source of guidance as a parent, leaving a legacy of providing a moral compass and many examples of how to properly engage life. Now she is gone from this physical world but she will not be forgotten. Eternal grace to her.
