Our Team

Cristina Mancillas Ramos, FNP-C

Family Nurse Practitioner

Cristina Mancillas Ramos, FNP-C, is a board-certified family nurse practitioner passionate about expanding healthcare access throughout Kern County. She is based out of the Adventist Health’s mobile unit but will also be providing care throughout Eastern Kern County, Tehachapi, Delano, McFarland and beyond.

She offers patients pediatric, adult, and geriatric primary care, including for chronic and acute medical conditions, sports physicals, wellness exams and more. She’s fluent in both English and Spanish. A firm believer that healthcare is a right and not a privilege, Ramos was inspired to practice medicine because she wants to help others and give back to her community — especially those most in need.

Our mobile unit staff is bilingual and includes a nurse practitioner, a clinic manager, two medical assistants, and an LVN.
