About Us

PANACEA (O’Neill Medical Group)

Serving Madison since 1994.

Serving Madison since 1994. Founded by Dr. Patrick J. O’Neill, who was a great doctor, physician, friend, husband and father to all. Panacea this day still strives to deliver on the three pillars of health care he believed in:

Availability – established patients should never wait more than same day or within 24 hours for an acute appointment

Affability – Our office operates by and holds all accountable to a code of conduct and mutual agreement with patients

Ability – We are an all physician clinic, patients can expect to see an actual doctor in charge of their healthcare at each and every appointment


PANACEA’s philosophy is to provide quality healthcare services (preventative medicine & disease management) for the whole family. Our goal is to heal through solving the core problems, rather than simply medicate the symptoms. We assess the health issues and work with the patients to solve the cause of symptoms with a combination of lifestyle changes (exercise, eating habits, etc…) and appropriate pharmacological solution. The aim of this clinic has and will always be to provide timely, accurate and preventative care for all ages.
Serving Madison since 1994.
