Catholic Health and Buffalo Medical Group have announced a new partnership aimed at expanding oncology, hematology, and infusion services across Western New York. The collaboration is intended to make cancer care more accessible for residents throughout the region, from Niagara County and the Northtowns to Buffalo and the Southtowns.
The organizations stated that most cancer care occurs in community settings, making it important to improve access and continuity through an expanded physician network and a broader geographic reach.
“We are excited to take this next step in our partnership with Buffalo Medical Group,” said Joyce Markiewicz, President & CEO of Catholic Health. “Their 80-year legacy of clinical excellence aligns with our commitment to innovation, compassionate care, and delivering the best possible outcomes for our patients.”
Robert Zielinski, MD, oncologist and Associate Medical Director at Buffalo Medical Group, emphasized the patient-focused nature of the agreement. “This is truly a patient-first partnership,” he said. “By combining our expertise and resources, we can deliver high-quality cancer care that is also cost-effective—an increasingly important priority for patients—while continuing to meet the evolving needs of our community.”
Both organizations noted that they will continue collaborating with Roswell Park Comprehensive Cancer Center on complex cancer cases. “As we strengthen community-based cancer care, we are fortunate to have Roswell Park Comprehensive Cancer Center as a regional resource for the most complex cancer diagnoses,” added Markiewicz and Dr. Zielinski. “We will continue to work closely with them to ensure patients receive the right level of care, at the right time, in the right setting.”
