The eldest of five children, Sue was born in Alhambra and raised in the San Gabriel Valley. She attended Arroyo High School and Rio Hondo Junior College. She met her husband, Bob Endress, while working at the University of Southern California where she worked in Human Resources. After they were married, they moved to Newhall in 1978.

Growing up in the San Gabriel Valley, Newhall was quite a cultural shock — no malls, major restaurants, theaters, horse tracks or beaches. After a few months, the quaint community of Placerita Canyon grew on her, and she knew she would live in this area for the rest of her life. Their first daughter, Casandra, was born in 1979, and Nicole followed in 1983. Rounding out their family is stepson Bobby and his wife, Melinda; their son Jake; stepdaughter Belinda; Casandra's husband, Matt; granddaughters Avery and Ryann; and Nicole's husband David.

Sue and Bob started Unicom Wireless in 1980, selling two-way radio systems and service, pagers and cellular phones. They still work closely with the community, schools and municipalities, serving their communication needs. In 2006, thinking she needed yet another challenge in her life, she opened Sue Endress Insurance Services to assist families with their insurance needs.

Sue's volunteer spirit started as a child with her mother and father, who volunteered in their church and schools. They were always at some project in the community or helping a family needing assistance. Sue has worked hard to instill that spirit of volunteering in her own children.

Sue's primary support and dedication through the years has been the Santa Clarita Valley Senior Center. She has watched it grow from serving barely 2,000 seniors per year to serving more than 10,000 annually. She has been involved with numerous fundraising activities, events and programs. She was a founding member and trustee of the former Santa Clarita Valley Senior Center Foundation.

She has also been involved with the other end of the age spectrum — children — through her years with Girl Scouts, the Hart High School Band Booster Club, PTA, and more. Although she no longer has children in school, and although she actively operates two successful businesses, she still donates countless hours to work with kids through the Rotary Club, where she has guided and mentored approximately 1,000 students at four local high schools, teaching them the principles of ethics and the importance of service to others.
