The Arlanza Health Center is situated at 8856 Arlington Ave., Riverside, CA 92503, in the heart of the Arlanza Community. The Mark T. Williams Arlanza Family Health Center has come to help the community as it helps itself. In partnership with Borrego Community Health Foundation, as the clinical operator, a broad range of health services for both adults and children are provided in a culturally familiar and access-friendly atmosphere. Competent, timely, family-centered care, emphasizing preventive strategies, characterize the Center's mission. About 16,000 patient visits are received annually, and the Center has become a hub of community driven health education initiatives. This center is home-base to the Promotoras outreach staff, its Teen Programs, and the Arlanza’s women’s advisory group, M.A.S. Much of the success has come from being incredibly involved in the community. It’s our goal to have a great impact through Health Workshops, Food and Nutrition Programs, Exercise Classes and Youth Initiatives offered, including Teen Clinic.
