St. Louis was born and raised in New England, the second of six
children. He attended secondary school at Phillips Academy,
Andover, and did his undergraduate studies at Harvard
College. There he majored in Biology, and graduated Cum
Laude in 1980. During his career at Harvard, he did
research at the Scripps Research Foundation (San Diego) in the
Department of Cellular Biology where he helped develop a
novel procedure for isolating DNA-cleaving enzymes. He also spent
a summer as a stagiaire de formation (general internship)
at the Centre Medicalle de Forcilles near Paris, France. He earned
his varsity letter in swimming as a springboard diver.
Dr. St. Louis attended the University of Massachusetts
Medical School where he graduated second in his class in 1984.
While attending medical school, he did independent clinical
research in Seattle, and published three peer-reviewed journal
articles in the fields of cardiology and emergency medical
services (cardiopulmonary resuscitation). He also married his
college sweetheart, Robin.
In the summer of 1984, Dr. St. Louis left the northeast and
moved to Los Angeles where he completed his internship and
residency in Internal Medicine at the UCLA Medical Center. There,
he was among a select group of 12 doctors who participated in the
General Internal Medicine specialization tract, which offered
exposure to office-based disciplines (such as orthopedics,
dermatology, gynecology, neurology, pain management) in addition
to traditional intensive adult-medicine training.
After residency training, Dr. St. Louis was recruited to
join the Sansum Medical Clinic in Santa Barbara, California.
He practiced at the Clinic for three years, enjoying staff
privileges at the Santa Barbara Cottage Hospital and appointment
to the Clinical Faculty of the USC School of Medicine.
In 1990, Dr. St. Louis elected to move from the coast to the
desert in order to open a solo practice of Internal Medicine. He
has been proudly associated with the Eisenhower Medical Center
ever since, having served as chairman of both the hospital's
Institutional Review Board and Pharmacy and Therapeutics
In 2003, Dr. St. Louis shifted the scope of his practice to create
the desert's first dedicated boutique-style practice.
Dr. St. Louis resides in Palm Desert with his wife and two
children, Andy and Carrie. He is active with the Desert
Bicycle Club, and can be seen pedaling more than 100 miles per
week around Valley streets. When not on the bike, he
"relaxes" on the golf course, diligently trying to
maintain his single-digit handicap.
