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. 



Dr. Patrick O’Neill has been serving Madison AL community since 1994.  He completed his Medical Education in Ireland, began his medical career in Canada where he practiced for over 20 years and immigrated to the USA in the early 90’s.  He is a board certified Family Physician.  He established his clinic which evolved into Panacea O’Neill Medical Group in 2010.  His medical priority has always been an interest in preventative care.  Furthermore he has held the belief of a medical doctor’s responsibility is to be available and affable.  To that end he has done his best to make sure his clinic runs efficiently and can do its best to serve same day appointment requests.  He treats patients of all ages and his patient roster includes many families of multiple generations.  He is husband to Mary and father of five children.  As a three sport varsity athlete in College, he is a keen sports enthusiast.
