Banner Ironwood Medical Center has broken ground on a 32,000-square-foot expansion that will give Queen Creek its first local emergency cardiac catheterization lab, a milestone that means residents suffering heart attacks may no longer need to be rushed to hospitals farther into the East Valley for critical care. The project also expands the hospital's emergency department, adding capacity in a town whose population has exploded over the past several years.
The new two-story building will include an interventional radiology suite, pre- and post-operative space, and room for future growth, according to AZ Big Media, which reported on the groundbreaking. The expansion will also widen the emergency department lobby to improve patient privacy and wait times, and it is designed to create a smoother, safer path for patients from admission through discharge. Mortenson is leading construction on the project, with Archsol serving as project architect, and the work is slated for completion in December 2027.
While the groundbreaking announcement centered on the new radiology suite and ER lobby improvements, earlier disclosures to Queen Creek town officials filled in the clinical stakes. When hospital leadership first presented plans to the Queen Creek Town Council in mid-2025, they revealed the expansion would grow the emergency department from 34 to 49 beds and add 80 new parking spaces, according to the Daily Independent. That earlier presentation is also where the cardiac catheterization lab first surfaced publicly, described as bringing both emergency and routine cardiac services to Queen Creek for the first time.
A Campus Built for This Moment
Banner Ironwood opened its doors on November 1, 2010, as a $150 million, 78-acre medical campus at Gantzel and Combs roads, according to Healthcare Construction & Operations. The site was master-planned from the start to accommodate long-term growth up to 500 inpatient beds and supporting specialty facilities as regional demand increased, per data from LoopNet and Plaza Companies, meaning the current 32,000-square-foot addition represents just one phase of a much larger long-term vision for the property. Banner Ironwood is now led by CEO Darren McCollem, who took over the role ahead of the August groundbreaking after former CEO Brian Kellar introduced the expansion plans to town council the year before, the Daily Independent reported.
Today the hospital sits at 37000 N. Gantzel Road and has served the Queen Creek community for more than a decade. The expansion comes as the town's population has surged; U.S. Census Bureau estimates cited by the Daily Independent show Queen Creek added more than 30,000 residents between 2020 and 2025, growing at an annual rate exceeding 6% to top 71,000 people by 2026. That growth has made Queen Creek a consistent fixture on lists of Arizona's fastest-growing municipalities, and it's the demographic pressure driving Banner's decision to add emergency and critical care capacity now.
Part of a Broader East Valley Building Boom
Banner Ironwood's expansion isn't happening in isolation. It follows Banner Health's $243 million patient tower addition at Banner Gateway Medical Center in Gilbert, completed in 2023, and ongoing modernization work at Banner Desert Medical Center in Mesa, according to AZ Big Media's broader reporting on the health system's East Valley strategy. Nearby, the $20 million Collective on Ocotillo medical office complex broke ground in Queen Creek in July, and the $45 million Terraza Medical Village is underway in neighboring San Tan Valley, as reported by In Business Magazine — signs of a regional healthcare buildout racing to keep pace with outward residential migration across Maricopa and Pinal counties.
Banner also already runs specialized emergency infrastructure out of Queen Creek beyond the hospital itself. As Hoodline previously reported, the Banner Air emergency helicopter team based at a local helipad became the nation's first air-ambulance service to carry and administer Antivip antivenom directly in flight for desert snakebite victims back in 2021.
A Nonprofit System With Deep Pockets and a Big Footprint
Banner Health, which operates 33 hospitals and more than 400 sites across six states, is headquartered in Arizona and describes itself as a fully integrated nonprofit healthcare system that includes health insurance, physician networks, specialty services, and behavioral health, per the AZ Big Media report. The nonprofit says it reinvests every dollar it generates back into its communities and provides more than $1 billion annually in community benefit, with a stated mission to address growing community needs for accessible, quality healthcare while working to reduce overall health spending.
The system's finances suggest it has the resources to sustain a multi-hundred-million-dollar East Valley growth strategy. Banner Health recorded $8.4 billion in total operating revenue and $966.6 million in net income during the first half of 2026, up from $7.9 billion in revenue over the same period in 2025, according to Becker's Hospital Review, with growth partially driven by state-directed Medicaid payment program increases. Banner is also Arizona's largest private employer, supporting 140,000 total state jobs — including nearly 60,000 direct employees — and generating an estimated $12 billion in annual statewide economic impact, the system says.
Banner Health also partners with the University of Arizona, driving clinical discoveries across more than 800 trials and training more than 1,300 residents and fellows annually, according to AZ Big Media's reporting. For Queen Creek residents, though, the more immediate significance of the Ironwood project is local: a cardiac catheterization lab and expanded emergency beds that promise faster, closer access to critical care as the town's growth shows no signs of slowing.
