Becky Sanford

Becky Sanford, Lead Navigator

As the daughter of a World War II Air Force veteran, Becky Sanford grew up in a military culture. Every uncle on both sides of her family was a combat veteran. Her brother and former husband are combat veterans from the Vietnam War, and her one nephew is currently deployed overseas as an EOD Specialist. Becky says she has a wide “red, white and blue streak” in her and is very tied to serving the veteran community. After a career in education, Becky returned to school, attending USC for her Master’s degree in Social Work (MSW) where she specialized in military and veteran issues. Since that time she has worked in Los Angeles with homeless veterans. In addition, Becky was a USC Field Instructor overseeing second year interns. Becky is now an official “San Diegan” and joined Zero8Hundred, eager to help smooth the road for our transitioning military populations, both veterans and their families. Additionally, she will serve again as a USC Field Instructor, working with our navigators who are MSW graduate students.
