Residency: Residency: Conemaugh Valley Memorial Hospital, Johnstown, Pennsylvania

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

Personal Information

Dr. Knox came to Hilo as one of the founding faculty of this residency. Seeing the success of this program is one of his proudest professional accomplishments. After over thirty years teaching residents and medical students, 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.

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.
