HIMSS positively transforms health and healthcare through the best use of information and technology. Our Southern California chapter is one of more than 50 affiliated chapters of HIMSS, the largest health care information systems professional organization in the nation. Our purpose is to bring health care professionals together to promote the exchange of experiences and knowledge among colleagues and to assist members in their professional growth. We accomplish these objectives by presenting educational seminars/conferences, networking opportunities, and a forum for the exchange of ideas among those committed to the goal of improving patient care through the effective use of information technology.

Our chapter members come from diverse backgrounds, all involved in some aspect of health care information systems and management. Our members consist of professionals from hospitals, clinic organizations, third-party payers, administrators, information technology vendors, nurses, consultants, physicians, and essentially anyone interested in the trends of health care information and management systems. Our membership spans across Los Angeles, Orange, San Diego, Santa Barbara, Imperial, Kern, Riverside, San Bernardino and Ventura counties with approximately 2,700 members. 

Ronald McDonald House of Orange County

The Orange County Ronald McDonald House and Ronald McDonald Family Rooms provide a comforting "home away from home" for the families of seriously ill children receiving treatment in Orange County hospitals.

The doors of the Orange County Ronald McDonald House opened in November 1989. Since that time, it has adjusted to a changing ratio in care for children from almost all cancer-related stays to about an even split between families with children who need cancer treatments and those that need neonatal care, which together account for about 70% of those who stay at the House.

The Orange County Ronald McDonald House is a program of Ronald McDonald House Charities of Southern California.
