Jason R. Frye PhD: My family and I moved up to Tuolumne County in 1976 from Southern California. As boy growing up in this area, I watched the many changes we have gone through. From the rocks and the gentle slope of the hill that is now known as the Junction, to the Walmart shopping area that was once just a cattle field. When I was 21 I joined the United States Army as a Military Police personnel, upon departing from service, I lived in Springfield Missouri, then moved to Nevada where I became a Deputy Sheriff working for the Lander County Sheriff’s Office. After my employment with the Lander County Sheriff’s office, I moved back to Tuolumne County California where I eventually opened my construction company in 2003. After 8 years in business, the housing market crashed and I decided to move on to the counseling field. I started working at Rite of Passage where I was a coach/counselor working with Juvenile Boy’s that were sent to the facility to change their behavioral patterns, and eventually I became the construction vocation / shop teacher working under Eldorado Office of Education. I then worked for Center Point Inc. at the Jamestown Corrections Facility as a Substance Abuse Counselor, and later I worked as a Recovery Counselor II for the Tuolumne County Behavioral Health. It was at this time I decided to attend school to get my PhD in Psychology. I recently completed my PhD in Psychology and am attempting to complete my hours of professional experience to become licensed as a clinical psychologist. I have been teaching and managing in various private colleges for the last 12 years while attending school. I began my teaching career with Heald College in 2011. I started as an Adjunct Instructor for the Criminal Justice Program, and was moved around as needed between Business Programs, Criminal Justice, and General Education. In September of 2011 I was offered full time employment as the Psychology Instructor with Heald College. I taught psychology for the next four years until Heald Closed its doors in 2015. I then taught for Devry University in Folsom Ca, and I was a visiting professor for Chamberlain School of Nursing (a sister college of Devry also in Folsom Ca). In 2018 I applied for a position in the Electrician Training Program at San Joaquin Valley College in Salida Ca, and worked my way up to the Program Manager. In November 2020 I applied for your Education Manager, since it was closer to home and more in line with my desired goals in Education. I am proud and Honored to be a part of your Education Department, I hope to bring in new opportunities, and programs that provide new horizons for the Tuolumne Me Wuk Tribe.
