About Banner Thunderbird Medical Center  

Our History

In 1960, the founders of present-day Banner Thunderbird Medical Center opened a facility at Northern and 61st Avenue named Northwest Hospital.

This hospital was the culmination of a decade-long struggle to build a community hospital to serve the health care needs of the Northwest Valley's 40,000 residents. 

In 1983, the hospital - then named Glendale Samaritan Hospital - moved north to its current location at 55th Avenue and Thunderbird Road, where a 150-bed facility was opened. At this time, the Northwest Valley population had swelled to 340,000 residents.

The growing need for services has never stopped. Today, Banner Thunderbird serves a market of more than 1 million people. To accommodate their needs, we launched a $290 million expansion project in 2007 that increased the size of the hospital to 561 beds.

Expanding to meet the needs of the community

The expansion project, which was recently completed, added a new 200-bed patient tower, new main entrance, larger Emergency department, cafeteria and dining room, state-of-the-art surgical suites, a new heart and vascular center, and more beds for pediatric patients.

Despite the growth and change, our dedicated employees, volunteers and physicians still adhere to the core values that make health care a noble calling: to treat each patient and each other with compassion, dignity and respect.

It's truly been a legacy of care and the story is far from over. Stay with us as we live out that legacy and strive to meet not just the health care needs of the community, but to exceed them one patient at a time.
