Lisa Hazelwood, HR Advisor

Lisa’s passion for animals and desire to help find long-term solutions to the homeless pet problem in her community has led her to join the VHS Board of Directors in 2012. As a young girl, Lisa was introduced to the harsh reality of pet overpopulation when a box of kittens was abandoned overnight in her parent’s driveway. Although her family adopted two of the kittens and found homes for the others, the experience left a lasting impression helping to shape Lisa’s views on the importance of responsible pet guardianship and the impact that spay/neuter and animal adoption programs have on bettering the lives of companion animals.

Lisa grew up in Pleasanton and moved to Southern California after high school to study music at CSU, Northridge.  She relocated to the Midwest where she continued her graduate studies receiving master’s degrees in Music Therapy and Health Services Administration from the University of Kansas. Lisa has worked as a Human Resources professional in the high-tech industry for nearly twenty years, including managing the employee benefits and retirement programs for Equinix, Inc. in Redwood City. Lisa and her daughter are fortunate to share their lives with three amazing rescue cats: Hailey, Twyla, and Lucky.
