ONS Leadership

ONS is governed by our President Jessica MacIntyre, DNP, MBA, APRN, NP-C, AOCNP®; an elected Board of Directors; and Chief Executive Officer Brenda Nevidjon, MSN, RN, FAAN. These dedicated representatives set our strategic direction so that we can best influence oncology nursing and the care of patients with cancer. Each leader has a long history of involvement with ONS, and together, they combine decades of experience in nursing practice, research, administration, and nonprofit leadership.
