I earned my MD degree from LSU School of Medicine in New Orleans in 1973. I served a pediatric residency in the LSU Division of Charity Hospital in New Orleans. I am certified by the American Board of Pediatrics and am a fellow in the American Academy of Pediatrics. I earned my BS degree in biological sciences from University of New Orleans in 1970. I received my YAT degree from Jesuit High School in New Orleans in 1965.

Thinking that I wanted to be a country doctor, I moved to Opelousas to begin private practice in July 1976. I discovered quickly that I didn’t want to be a country doctor. I moved to Baton Rouge in July 1977 and have been in independent private practice since then, except for the period October 2009 through May 2010. During that time, I was a member of the faculty of Our Lady of the Lake’s Pediatric Residency Program. In June 2010, I returned to the independent private practice of pediatrics and adolescent medicine.

I am lucky to have a beautiful and talented wife, who is my inspiration. We have three grown children, all model citizens, thanks to my wife’s diligent rearing abilities. We are the fortunate grandparents of four healthy and adorable (of course!) grandchildren.

I have accumulated an average of 45 hours of formal Continuing Medical Education credits each year for the past 15 years, and countless other hours reading the pediatric, medical and scientific literature on a daily basis. I strive to practice the art and science of pediatrics diligently and conscientiously. I discuss the best evidence-based diagnosis and treatment with my patients; I treat, interact with and suggest therapy for my patients, just as I would want another doctor to treat my family members. I have been voted by my peers as one of the Best Doctors in America© each year since 1996.


Pedægis is pronounced PEED-uh-jiss, accent on the first syllable. It is derived from the Greek words παῖς (pais, meaning “child”) and αιγίς (ægis, meaning “knowledgeable protection”). It reflects those qualities that parents want from a pediatrician: educated and experienced protection from disease and injury for their children. It is the business name of Dr. Coogan’s practice.

    Hi there,

    I really enjoyed reading your editoral response about alternating acetaminophen and ibuprofen. We were recently told to do this for our son after a febrile seizure by the er doc. I questioned it as I was aware of the literature on it that advised doing so with caution and the risks (being a nanny and parenting author). She advised to do anyway. Well, after a long night with little sleep due to our son’s fever and still recovering from the emotional tramua of the seizure, even with a log sheet and predrawn doseages using the appropriate syringe, my husband gave two doses of motrin, instead of one of tylenol…and he works in the medical field. So….even intelligent folks who understand the instructions and take the proper precations, can easily mess up! – Michelle
