About Colleen A. Finnegan

Before entering the medical field, Dr. Colleen Finnegan, used to be a ballet dancer and was always fascinated by how the body moved and worked. Then, in the 1980's the HIV crisis came, and she felt a need to help a population that was very ill. “I chose internal medicine so that I could pursue both HIV and general internal medicine care,” says Dr. Finnegan. “This way I would gain broad and specific medical knowledge to be able to care for many different patient populations.”

In addition to evaluation and treatment of a patient's specific concerns, medical prevention is a primary focus in her practice. I truly believe it is the cornerstone of living a longer, healthier life so that each person has the potential to pursue their own personal goals. I hope to offer a safe and respectful environment where the patient can feel comfortable sharing their concerns, so that we can optimize communication, clarify goals and come up with a plan to improve health.

Dr. Finnegan earned her medical degree from Tufts University School of Medicine then completed her internship and residency at Oregon Health & Science University. She specializes in internal medicine but is also HIV credentialed.

Her philosophy of care is to medically improve a patient's quality of life, whether in the acute setting or over many years. Her hope is to have a mutually respectful relationship where she and a patient can decide which medical options are the healthiest for the patient.

When she’s not working Dr. Finnegan likes to read, travel, spend time with her family/friends, and regularly exercise. She enjoys going to plays and to the ballet as well.
