Partnering with you

We understand the needs and priorities of oncology practitioners and payers, and are committed to providing responsive, data-driven service. Our goal is to partner with you and provide the resources and perspective to support the right treatment choice, for the right patient, at the right time in the course of therapy.

Bringing a clinical and scientific focus

All of our Merrimack Oncology Partners have degrees in nursing, pharmacy, and/or medicine to bring a clinical and scientific focus to their discussions with you. We are committed to providing the information you need to make decisions that keep the best interest of the patient's treatment in mind.

Continuously learning

We take improvement seriously. We are committed to evolving how Merrimack can best support you by seeking in-person feedback. Additionally, through our online portal,, we hope to continue to receive further input from the oncology community, even when we’re not face-to-face.
