HMS Medical Services

“Primary care providers work within a Patient Centered Medical Home (PCMH) model that works to improve health outcomes through care coordination and optimizing health outcomes”

HMS medical doctors, nurse practitioners and physician assistants work in a team-based approach to deliver comprehensive and integrated services with the support of highly qualified nurses and medical assistants. HMS medical services are provided to all age groups, which also includes prenatal care and obstetrics, and many of our providers offer services at Gila Regional Medical Center.

Patient Feedback

“Dr. Amendariez was great! He addressed all my concerns.”

“My son would be afraid to go but because Dr. Etheridge hands out books my son is excited to go to the Dr. These gifts really help the visit be less stressful. I love that it’s not candy or a toy, it's a book that can teach him!”
