CASA for Safe & Healthy Neighborhoods has operated from La Mesa's University Avenue since the organization's founding in 1988, mobilizing communities to reduce substance abuse and tobacco access across San Diego County. The 501(c)(3)'s tobacco-control and smokefree-housing advocacy work complements the recovery-focused programming at Parentcare Family Recovery Center, which addresses substance-use disorders through residential treatment. Classified under NTEE code F20 for alcohol, drug, and substance-abuse prevention, CASA (EIN 33-0337244) holds a 96-percent rating from Charity Navigator and operates with an all-volunteer board of directors. Public health internships for high school and college students train the next generation of advocates, a youth-leadership model that intersects with the adolescent behavioral-health services at Evolve Adolescent Behavioral Health: Mount Helix. Highest-impact initiatives include countywide retailer-licensing campaigns that restrict tobacco sales density near schools and the enforcement of smokefree policies across multi-family housing complexes in the 91942 corridor.
