About Us

About HCH510

HCH510 was established in early 2017 by the Asian Health Services HIV prevention and care department to destigmatize HIV within Alameda County. HCH510’s vision is to encourage people of color within the city of Oakland and Alameda County to practice well-rounded care by offering inclusivity through education, resources, prevention, and treatment.
