Board of Directors

Meet the PHNTX Board

Remembering Board Member Joey Avila

We are deeply saddened by the tragic loss of Joey Avila, a longtime member of our community and a dedicated board member of Prism Health North Texas.

Joey’s service was rooted in a broad commitment to equity, justice, and community access. For nearly three decades, he was an outspoken advocate who used his voice and time to create meaningful change, supporting the HIV/AIDS and LGBTQ+ communities, advancing initiatives within the Black community, and volunteering to improve access to healthcare. His dedication was evident in everything he did, from raising critical funds for organizations across North Texas to staying actively engaged with the City of Dallas through the Citizens Police Academy and service on city committees.

Joey will be remembered for the lasting impact he made, his kind and gentle spirit, and his unwavering passion for advocacy. His legacy will continue to live on through the countless lives he touched.

We extend our deepest condolences to his loved ones and all who had the privilege of knowing him.

 

The PHNTX Board of Directors provides long-term direction that helps shape the success of Prism Health North Texas. Board expertise and insights help PHNTX promote access to healthcare for marginalized populations including HIV/AIDS, LGBTQ, and ethnic minorities.
