BUFFALO, NY— Erie County Medical Center Corporation (ECMC) today announced the promotion of Cassandra “Cassie” Davis, MS to Chief Operating Officer. The promotion will take effect on Monday, June 15th. Ms. Davis succeeds Andrew L. Davis, MBA, who will begin his tenure as President and CEO at ECMC on June 15th. Mr. Davis succeeds Thomas J. Quatroche Jr., PhD who is departing ECMC to become President and CEO of the Healthcare Association of New York State (HANYS). She began her career at ECMC in 2008 in Care Management.
In her immediate previous role at ECMC as Senior Vice President of Operations, Cassie oversaw multiple key clinical service areas, including: surgical, rehabilitation, ambulatory, population health, pharmacy and lab services. In addition, she was responsible for plant operations and all capital matters throughout the institution.
Andrew L. Davis, MBA, President and COO, ECMC said, “Over the course of her 18-year career at ECMC, Cassie Davis has participated in and led several key initiatives and programs that have made significant contributions to ECMC’s continuing development, growth and vitality. She has been at the forefront of our efforts to strengthen our clinical programs and she is widely recognized throughout our institution as a key member of our Executive Leadership Team. Her extensive knowledge and experience will play a central role in her new position as Chief Operating Officer, overseeing all aspects of ECMC’s day-to-day functions. Throughout her career at ECMC, Cassie is well-known for her collaborative and hard-working nature, always keeping the interests of ECMC, our caregivers and our patients in the forefront of everything she does. I look forward to working with her as we continue to develop and execute the efforts to maintain and expand ECMC’s high-quality clinical services.”
Among her notable contributions and accomplishments were the introduction in 2025 of the Symani® Surgical System, a first-of-its-kind robotic technology that uniquely addresses the scale and complexities of microsurgery, making ECMC the first hospital in Western New York to house this surgical technology. The System enabled surgeons at ECMC to use microsurgical techniques with robotic precision to perform reconstruction of small blood and lymphatic vessels to help restore quality of life for more patients. Also in 2025, thanks to Cassie’s efforts, ECMC opened its new Breast Health Center, which provides a full continuum of care, from education and screening to reconstruction and oncology treatment in one centralized location. The new Breast Health Center offers mammography patients the gold standard in 3D imaging using Hologic Dimensions equipment as well as the Hologic bone density (DEXA) system.
Breast ultrasound also playing a critical role in mammography is performed on a state-of-the-art Toshiba Sequoia unit. These services are offered daily and in one convenient suite allowing the patient to move comfortably between modalities. The Center, the first bricks and mortar mammography suite in the Delevan-Grider neighborhood, supports the immediate needs of the neighborhood’s residents, which is listed as “highest need” on the City’s priority needs ranking map.
In her previous role as Vice President of Ambulatory Services and Population Health for ECMC, Cassie covered a broad spectrum of duties affecting the health and wellness of the community, as well as many operational needs within the healthcare organization. She oversaw outpatient operations, including Primary Care and over twenty different Specialty Services, focusing on transformation of care delivery and growth of services. During the COVID-19 pandemic, her role significantly evolved and grew, including establishing processes and services to provide COVID-19 testing, monoclonal infusion services and vaccinations for both the ECMC healthcare staff and the general public. These efforts included working closely with New York State representatives to establish pop-up vaccination sites across the City of Buffalo and its suburbs.
Cassie represents ECMC and participates in several community partnerships and collaborations across Western New York. She is Board Chair at the Crisis Services Foundation and is a member of the SNAPCAP Inc. Board of Managers. She also completed a Fellowship with America’s Essential Hospitals in 2020.
She received her BS in Sociology, Justice in Society track from SUNY Oswego and her MS in Community & School Health from Canisius University.
