Tashelle Wright

Tashelle Wright

Central Valley Region

Tashelle Wright is a PhD candidate in Public Health at the University of California, Merced. She is currently a TRDRP Predoctoral Fellow working on her dissertation, which focuses on oral health and tobacco use disparities among underserved populations (e.g., older adults, Blacks, Hmong, Latinx, and immigrants) in California's rural Central Valley. Tashelle is the Media Subcommittee Chair of the Merced County ACCT Coalition (A Community Counteracting Tobacco).

Tashelle was introduced to the world of tobacco control in 2014 when she was working on her Bachelor’s in Public Health and working at the Utah Department of Health. She worked on several projects including a project educating tobacco retailers and a separate collaborative project to establish a sustainable African/African American/Black Health Taskforce.

Since moving to Merced, Tashelle has been interested in and involved with rural health issues including aging and caregiver health, tobacco and alcohol use, oral health disparities, and homelessness in the Central Valley. This interest stemmed from her growing up in a semi-rural environment and wanting to make a difference in the lives of rural communities. As tobacco-related disparities have a great impact on rural communities, her goal as a RISE Advisory Committee member is to continue advocating for tobacco control policies and conducting research that is culturally-relevant and community-based.

Rexanne Greenstreet

Rexanne Greenstreet

North Valley Region

Rexanne Greenstreet (she/her) was born and raised near Seattle, Washington. After receiving her Bachelor of Science in Community Health from Western Washington University, Rexanne continued on to a career in youth development and non-profit leadership. In 2018, she traded in rain and trees (which she loves) for surf and sun (which she also loves) and moved to San Diego, CA. When COVID-19 ushered in another round of life change and job loss, Rexanne used the unexpected shift to return to her passion – empowering and effecting change in communities to reduce health disparities. Rexanne joined the American Lung Association in Chico, CA in January of 2021 and quickly found her home as a self-proclaimed “public health policy nerd” in the tobacco control community. Outside of work you will usually find Rexanne near trees, listening to podcasts while baking, or talking incessantly about her dog, “Nug.”
