Our History

New Hampshire Oncology-Hematology, PA (NHOH) was founded in 1976 by Dr. A. Collier Smyth. Trained at the renowned National Cancer Institute, Dr. Smyth was the first board-certified oncologist in community practice in New Hampshire. His vision was to bring world-class oncology and hematology care to New Hampshire. NHOH has remained dedicated to that vision of excellence, innovation and research-driven advances in medical care. As an example, in 2007 NHOH earned national recognition as one of only 10 community oncology practices in the country to be honored with the Clinical Trial Participation Award presented by the American Society of Clinical Oncology. Every member of our team is committed to leading the way to bring the most progressive and effective treatments to our patients right here, in their own communities.
The task of caring for people with serious and complex illnesses cannot be accomplished by any individual alone; it requires a team working together. Today our team consists of more than 100 staff members including 10 board-certified or board-eligible oncologists/hematologists, a board-certified internist who is NHOH’s hospitalist, physician assistants and nurse practitioners, certified oncology nurses, clinical pharmacists and pharmacy technicians. Visit the Staff section of our website for an introduction to many of these dedicated health-care professionals.


NHOH is a medical group practice with four locations throughout the central and southern New Hampshire region. Our locations are Manchester, at the Solinsky Center for Cancer Care at Elliot Hospital, and in Concord, at the Eugene and Anne Slusser Medical Oncology Suite at the Payson Center for Cancer Care at Concord Hospital. For the convenience of our patients, we provide care in Laconia at Lakes Region General Hospital, and in Londonderry at the DFCI/NHOH Office.
The care of patients with cancers or diseases of the blood requires the coordination of treatment planning among a network of physicians and institutions. At NHOH, we work closely with surgeons, radiation oncologists, and primary care physicians. We maintain close collaborative relationships with area community hospitals including: Elliot Hospital and Catholic Medical Center in Manchester, Concord Hospital, and Lakes Region General Hospital in Laconia. In addition, we are a clinical affiliate of the Dana-Farber Cancer Institute and work closely with the major regional teaching hospitals and cancer centers.

Clinical Research

In order to make the most up-to-date care available to our patients, we have a vigorous clinical research program at all of the NHOH practice sites. A full description of the meaning of clinical research, as well as the types of research projects and clinical studies we are conducting, can be found in the Research section of our website.
