OhioHealth has commenced construction on a $226 million Comprehensive Outpatient Cancer Center at its David P. Blom Administrative Campus at 3430 OhioHealth Parkway in Columbus, Ohio — marking the formal start of a project that will create central Ohio’s most integrated destination for outpatient oncology care. Construction fencing was installed in March 2026 to enclose the south surface parking lot on which the five-storey, 199,000-square-foot facility will be built, with the completion date revised from spring 2029 to late 2028 and the building connected through the first four floors of the existing campus structure.

Designed by Design Group and HKS, and built by Gilbane Building Company, the new center will nearly double the campus footprint from approximately 250,000 to nearly 500,000 square feet and consolidate oncology services currently dispersed across OhioHealth Riverside Methodist Hospital, the Bing Cancer Center, and Columbus Oncology & Hematology’s Jasonway Avenue practice into a single purpose-built facility. In the neighboring state of Pennsylvania, TerraPower Isotopes is set to break ground a new $450 million manufacturing site in Bellwether District. The project also facilitates in the fight against cancer.

A Purpose-Built Destination: What the Cancer Center Will Offer

The Comprehensive Outpatient Cancer Center has been explicitly conceived around a principle that drives modern oncology facility design: the recognition that cancer patients undergoing multi-modal treatment — often simultaneously receiving radiation therapy, chemotherapy infusion, surgical follow-up, and imaging — should not have to navigate multiple sites, parking challenges, and separate scheduling systems to receive care that is inherently integrated. By bringing services that are currently distributed across multiple locations into a single five-storey building connected directly to the administrative campus, OhioHealth is eliminating the fragmentation that is one of the most persistent sources of patient stress throughout a cancer treatment journey.

The clinical programme is broad and deliberately comprehensive. Radiation oncology, surgical oncology, and medical oncology will all be available on site alongside a blood and marrow transplant programme, infusion services, diagnostic imaging, laboratory services, multiple specialised cancer clinics, and supportive and wellness services including the capacity to add new programmes and services as cancer medicine continues to evolve. The building is also designed to accommodate blood and marrow transplant — one of the most complex and resource-intensive inpatient-adjacent oncology services — which reflects OhioHealth’s ambition to serve patients with complicated and aggressive cancers who have historically needed to travel to larger metropolitan centres for that level of care. Jeff Ghebretnsae, the comprehensive outpatient cancer center accountable lead and OhioHealth’s clinical enterprise director for the oncology service line, has described the co-location of all oncology services under one roof as a development that will drastically improve the patient experience for those undergoing multiple treatment types simultaneously.

OhioHealth, Columbus Oncology, and the Project’s Leadership

OhioHealth — a nationally recognised not-for-profit health system chartered as a healthcare outreach of the United Methodist Church and serving communities since 1891 — is the project owner and primary clinical operator of the new cancer center. With 36,000 associates, physicians, and volunteers across a network of 16 hospitals, three joint-venture hospitals, one managed-affiliate hospital, and more than 200 ambulatory sites spanning a 50-county area in Ohio, OhioHealth is one of the dominant health systems in the state. Dr. Praveen Dubey, OhioHealth’s Vice President of Cancer Care, has been the clinical champion of the project since its announcement in December 2024, articulating both the access imperative and the patient experience rationale in language that resonates beyond the health system itself.

The cancer center also deepens a long-standing and strategically significant relationship between OhioHealth and Columbus Oncology & Hematology — a 16-physician independent community oncology practice with more than 37 years of service to central Ohio patients. Under the co-location arrangement, Columbus Oncology & Hematology will lease approximately 30,000 square feet within the new cancer center to operate a medical oncology clinic, infusion services, and pharmacy — consolidating their Jasonway Avenue practice into the new facility and becoming the third shared location in their partnership with OhioHealth, alongside the Dublin Cancer Center and the Westerville Cancer Center. Joseph Hofmeister, MD, President of Columbus Oncology & Hematology, has described the new center as an opportunity to strengthen their long-term alignment with OhioHealth, expand access to clinical trials and innovative therapies, and cultivate the integrated patient experience that community oncology at its best can provide. On the construction side, Gilbane Building Company serves as general contractor and Design Group and HKS — a joint architecture engagement combining a Columbus-based studio with an international firm known for its healthcare design portfolio — provide the architectural and design leadership.

The Blom Campus Transformation: Doubling a Footprint in the Heart of Clintonville

The David P. Blom Administrative Campus is located in Clintonville, a dense residential neighbourhood on Columbus’s north side, immediately southeast of OhioHealth Riverside Methodist Hospital — one of the largest hospitals in Ohio. The campus’s existing building covers approximately 250,000 square feet and houses OhioHealth’s central administrative and clinical coordination functions. The addition of 199,000 square feet in a new five-storey south tower — connected to the existing structure through the first four floors — will bring the combined campus to nearly 500,000 square feet, transforming what was a back-of-house administrative environment into a visible, patient-facing clinical destination.

The physical configuration of the connection between the new tower and the existing campus is clinically significant: it means that patients, clinical staff, and support services can move between the cancer center and the administrative functions — clinical informatics, scheduling, billing, logistics — without leaving the building. The project also includes renovation of portions of the existing campus structure and construction of a new parking structure to serve the expanded patient and staff population that the cancer center will attract. The phased relocation of services from Riverside Methodist Hospital and the Bing Cancer Center to the new building, and the parallel relocation of Columbus Oncology & Hematology from Jasonway Avenue, will be managed as a clinical transition programme that runs concurrently with the construction programme through 2028.

Columbus Cancer Care, OhioHealth’s Growth, and Ohio’s Healthcare Capital Investment Wave

The OhioHealth cancer center investment arrives in a Columbus healthcare market that is expanding rapidly in both population and institutional ambition. Columbus has grown into Ohio’s largest city and one of the fastest-growing major metros in the eastern United States, drawing a young, educated, and economically diverse population whose healthcare demands are both growing in volume and rising in clinical complexity. OhioHealth’s own workforce is growing to match: the system currently employs more than 400 cancer programme staff across its footprint, and has committed to adding a further 140-plus oncology positions over the next decade — a roughly one-third expansion of its oncology workforce that reflects both the clinical programme’s growth and the labour planning required to operate a new purpose-built center at scale.

OhioHealth’s investment joins a broader Columbus healthcare buildout being shaped simultaneously by its crosstown rival, with Ohio State University’s $1.8 billion Wexner Medical Center Inpatient Hospital — a 26-storey, up to 820-bed facility and the largest single construction project in the university’s history — now open, collectively positioning Columbus as one of the most comprehensively served academic healthcare markets in the American Midwest.

The $226 million cancer center also sits within a broader OhioHealth capital investment programme that includes a separate expansion of OhioHealth Dublin Methodist Hospital to increase inpatient and critical care capacity, the ongoing growth of the Dublin and Westerville cancer center network, and a wider pattern of ambulatory and community care investment across the 50-county service area. Together these investments reflect the strategy OhioHealth’s leadership has articulated consistently: to serve as many patients as possible within their own communities, reserving the most complex care for a central, purpose-built destination that offers capabilities simply not replicable at a community hospital scale. For Columbus residents facing the most difficult cancer diagnoses, the late 2028 opening of the cancer center at 3430 OhioHealth Parkway will mean world-class oncology care within their own metropolitan area, delivered by a team whose integration across disciplines has been physically designed into the building from the ground up.
