After a quarter century of refinement, Dr. Knox feels that his main goal as a medical educator is to provide a learning environment that is challenging but that remains non-threatening and humanistic.

The opportunity to support the personal and professional growth of residents as they metamorphose from rookies to Family Physicians ready to begin their careers is a privilege and provides his inspiration as a teacher. Improving his ability to teach well has been the focus of his professional development.

As much as I like practicing medicine, the opportunity to teach residents is what gets me out of bed each morning.

Clinically, Dr. Knox has a special interest in caring for patients with HIV/AIDS and in inpatient and outpatient procedures.

Personal notes:

The great challenge in medicine is to balance your profession with the rest of your life. I am married and have two grown children. I have been a student of the martial arts and tai chi for almost thirty years. Like medicine, martial arts are rich and complex and provide unlimited possibilities for study and growth. My other hobby and significant social outlet is playing the bagpipes. No other kind of music will put you in touch with so many other eccentric people and test the limits of your family’s tolerance.

Albany Medical College, Albany, New York

I grew up picking crops until age 13 and worked closely with the farm migrant people. I learned a lot about nature in these years and was introduced to social inequality and social issues. I was late to the educational system and learned to read and write starting at the age of 16. I was touched by the hardships of people and had this overwhelming need to help. I got an AS degree in mental health and keypunching and held two jobs as I worked my way through college. I was accepted into medical school at Albany Medical College in Albany, NY. I was the medical director of 4 national health clinics in Idaho and helped to teach nurse practitioners. I was at a rural site in Idaho, for residents from Cleveland Clinic to rotate through, and was in private practice for approximately 20 years. The last 18 years I have spent working in rural health and teaching medical students and residents. I love to watch the growth of each individual and know that they are developing their own skills and their art of medication; for we need both the evidence base and the art of medication to be a productive provider. It is the warmth and sensitivity that we share with each other that allows each day to be special and cherished. I love working with patients, their families and residents, and feel privileged that this has been my life. I am lucky to be a doctor and to have shared so much.
