Warren Clinic

Architect: CallisonRTKL

Owner: Warren Professional Building Corporation

Location: Tulsa, Oklahoma

Category: Built - less than $25 million (construction cost)

This trio of clinics serving the Tulsa, Oklahoma, region are built on a modular approach to health care, allowing them to be patient friendly, highly efficient, and easily adapted to other potential sites in the area. Functionally, the clinics offer primary and urgent care as well as imaging services for the Saint Francis Health System, but their clinical prototype upends the traditional model and allows for seemingly endless configurations.

Each clinic features a modular pod concept that is organized around four physicians, a number that was determined to work best from an operational standpoint. The pods boast 12 examination rooms and ample support and work space. When multiple pods are linked, the support spaces can be easily shared, allowing each site to adapt to the needs of the community it serves.

The team embraced an on-stage/off-stage approach to enhance the patient experience while creating a comprehensive staff area. All visitors enter a gallery space and are then escorted to decentralized waiting areas that sit outside each exam room. The staff spaces, which remain separate from visitors to maintain confidentiality, encourage collaboration and provide staff members with direct access to each exam room.

“This project is focused on the patient experience throughout the clinic, and they did interesting things with the behind-the-lobby spaces. The way they dispersed the waiting room is similar to clinics in Asia and is unique for this setting...The plug-and-play aspect of this project is commendable; a lot of thought and care was put into the modularity.” - Jury comment

In addition to the overall design, the team was tasked with branding the clinics, and the color pink, a dominant shade found in the Saint Francis brand, was incorporated in the form of a glass wall. The wall frames the clinics’ garden spaces and stands as a visual icon for each site. Inside, the interior design is driven by the idea of light from above. Ample natural light and exterior views both reinforce the brand and enhance the experience for patients and staff.
