About Us

PANACEA (O’Neill Medical Group)

Serving Madison since 1994.



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.
