Fontaine MD Aesthetics and Anti-Aging Medicine

Dr. James Fontaine is a board-certified physician and the founder of Fontaine MD Aesthetics and Anti-Aging Medicine in San Diego. After earning his medical degree from the Keck School of Medicine at USC in 1990, he completed a residency in Physical Medicine and Rehabilitation at UC Irvine. Over more than three decades in practice, he’s shifted his focus toward preventive, aesthetic, and anti-aging care—areas where he believes medicine can truly improve quality of life, not just extend it. His training includes an aesthetic fellowship through the American Academy of Anti-Aging Medicine, along with advanced study in bioidentical hormone therapy under Dr. Neal Rouzier. Patients come to Dr. Fontaine for his thoughtful, science-backed approach to health optimization. Raised in Southern California, he’s still happiest outdoors, especially when mountain biking or spending time with his wife, Julie, and their sons.

Julie runs the show behind the scenes at Fontaine MD—though she’d probably just call it “keeping things on track.” As office manager and chief operating officer, she’s the one making sure everything flows: consultations, scheduling, finances, patient prep—it all runs through her. Before this, she spent ten years managing a plastic surgery practice, so she knows aesthetic medicine inside and out, not just from a clipboard. Her experience with procedures, products, and people is part of what makes the clinic feel so well put-together without being uptight. Patients and staff lean on her not just for answers, but for clarity. She's organized, yes—but also approachable, which is its own kind of rare. Her role might be behind the curtain, but you’d definitely notice if she weren’t there.

Sarah is a Registered Nurse who brings both clinical skill and a deep sense of empathy to her role at Fontaine MD. Born in San Diego and raised in Southwest Florida, she earned her Bachelor of Science in Nursing from the University of Central Florida. Before transitioning into aesthetics, Sarah spent over four years in bedside nursing, where she developed a strong foundation in patient care. Her interest in aesthetics grew from her understanding of how feeling good in one's own skin can impact overall well-being. Prior to joining Fontaine MD, she worked at one of California's largest medical and cosmetic dermatology practices, collaborating with board-certified dermatologists and honing her expertise in injectables, lasers, and cosmetic procedures. Sarah is known for her commitment to achieving natural-looking results and for her perfectionist tendencies that ensure each patient receives personalized, results-oriented care. Outside of work, she enjoys spending time with friends and family, being outdoors, and engaging in activities related to the ocean or water.

Louise brings a rare mix of creative instinct and clinical care to Fontaine MD. She began her professional life with a degree in art from Humboldt State, designing window displays for brands like Bloomingdale’s and Levi’s—work that demanded a sharp eye and attention to detail. Later, feeling drawn to something more hands-on and personal, she earned her Bachelor of Science in Nursing from Samuel Merritt University. For the past four years, she’s focused on aesthetic nursing, where that same eye for balance and proportion now helps patients look refreshed without looking “done.” She’s known for being thoughtful and careful—someone who takes time to understand what each patient hopes to see in the mirror. Whether guiding someone through a subtle enhancement or a bigger change, Louise approaches it with both warmth and precision.
