Doctors in Peoria, AZ

Banner Sun Health Research Institute has banked over 1,600 human brains since 1987 for Alzheimer's research, and the retirement corridor that supplies its donors also drives one of Arizona's sharpest splits between geriatric and pediatric demand. The median age of 41.7 and median household income of $96,000 reflect this mix. For cancer care, outpatient surgery, and imaging, HonorHealth opened a major 100,000-square-foot medical campus in Peoria in April 2025, with a second campus approved at FIVE NORTH in Vistancia. For uninsured and AHCCCS patients, Valleywise Health Center Peoria, a $70 million facility opened in 2021, provides safety-net primary and specialty care. For hospital-level emergencies, five full-service hospitals are within a 15-minute drive, including Banner Thunderbird in Glendale (Level I Trauma Center) and Banner Del E. Webb in Sun City West, which means a Peoria resident with a heart attack is likely in an ER within 10 minutes. Plaza del Rio, the largest off-hospital medical campus in Arizona (185 acres), connects directly to Banner Sun Health Boswell Hospital. For Alzheimer's research and clinical trials, Banner Sun Health Research Institute is nationally recognized, with a Brain and Body Donation Program that has banked 1,600 or more brains since 1987. The aging population drives high demand for geriatrics, cardiology, orthopedics, memory care, and home health. The Peoria Sports Complex hosts Cactus League spring training for the Mariners and Padres, generating seasonal sports medicine demand. Growing north Peoria neighborhoods beyond Happy Valley are 20 or more minutes from the closest hospital, a gap that matters most for time-sensitive emergencies like stroke, where every minute of delay reduces the chance of full recovery.
