PROVIDERS

All of our highly specialized providers currently on staff are American Academy HIV Specialist (AAHIVS) certified, or training for the certification. They are constantly looking for ways to promote our services and hone their skills, conducting research and attending conferences and meetings. Together, they work to create a pertinent conversation on the developments of HIV, hepatitis C, and transgender health care. The program has grown rapidly from a single provider in 2011 to several HIV and hepatitis C specialists working at four separate locations in Riverside County and San Bernardino County. Their compassionate approach to treatment is well regarded by our patients.

 

If you would like to make an appointment, please call (760) 676.5800.
