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

“Isaac Saucedo PA, litterally saved my life, sent me to the ER for treatment to evolving critical illness. He recognized the emrgency immediately and contacted the ER to expedite my care. In additon, he is by far one of the best providers out there.”

“Dara Foster is above excellent! She has provided excellent care and helped me through many issues like depression and cancer!”

“Tiffany Maxey is very thorough and never rushes through our visit. She explains things in detail to where I can understand and is very caring. She is the best provider HMS has!”

“Tiffany Maxey saved my life. She caught my ovarian cancer in time based on my symptoms that two other providers had missed. She is someone who really cares and takes the time to listen to you. My oncologist said it was caught in time and that it is often missed because of the subtle symptoms which Tiffany did not ignore. I owe her everything.”

“Edla Rucker, FNP, is the best! I've never had such a competent and caring provider”

“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!”
