Continuing Education Chair

Geovany Lizarraga 

My name is Geovany Lizarraga and I am a self-motivated individual within the Public Health community and a current MPH student at CSU, Northridge. Once graduated with my MPH, I wish to become a Health Education Specialist with a non-profit organization and acquire a position with Bakersfield College as an adjunct Public Health professor. I currently work at Dignity Health as a Healthy Living Program Specialist, where I disseminate nutrition education, physical fitness, and chronic illness self-management evidence-based programs. One of my biggest accomplishments as a Health Educator must be when I was left with the task of having to run a 6-week chronic illness self-management program and had such positive feedback from the participants, it made me feel so special and realized how much of an impact we as Public Health professionals can make in our community.

Some of my favorite hobbies include exercising, gardening, and cooking new recipes! Although I am a public health professional and MPH student, a previous work title of mine was “Beekeeper” and loved doing it because I got to travel and learn so much about bees and their lifespan.
