Additional Background


Dr. Peter St. Louis was born and raised in New England, 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 was a varsity athlete, and earned his 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, WA and published three peer-reviewed journal articles in the fields of cardiology and emergency medical services. He also married his college sweetheart, Robin.

Dr. St. Louis completed his internship and residency in Internal Medicine at the UCLA Medical Center. There, he was among a group of 12 doctors selected to participate in the General Internal Medicine specialization tract, which provided unique training in 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 moved to the desert in order to open a solo practice of Internal Medicine. For the past 25 years Dr. St. Louis has been proudly associated with the Eisenhower Medical Center and is an Appointee to the Operating Board of the Eisenhower Hospital.  He has held leadership positions on the Medical Staff including Section Chief of the Department of Internal Medicine and Chairman of both the Hospital’s Institutional Review Board and Pharmacy and Therapeutics committee.

In 2003, after having built a successful primary care practice in Rancho Mirage,  Dr. St. Louis shifted the scope of his practice to create the desert’s first dedicated concierge-style practice. His was one of the first 150 such practices in the United States, as reported by the General Accounting Office of the US Congress. Today, he continues to limit his practice to no more than 200 patients in order to provide unparalleled personal attention, unprecedented physician access, and unsurpassed medical care.

Dr. St. Louis resides with his wife full-time in Palm Desert. 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, on the tennis court or in the gym.
