Gateway Hancock Health Immediate Care Center
Greenfield, IN

Providing services in an area with few options, Gateway Hancock Health’s new free-standing immediate care center satisfies the needs of the community and its staff within a uniquely efficient and aesthetically bold facility. Patients now have access to labs and imaging, as well as blood tests, X-rays, ultrasounds, and many other services or tests needed.

O’Donnell & Naccarato utilized composite steel framing within the structural design of the medical office building. Decorative, built-up steel columns support the entry canopy and drop off, while special attention was given to ensure the stability of the large wing wall. Additionally, O&N completed the specialized design to support X-Ray and CT-Scan areas, including the support of the lead shielding.
