Your Trusted Partner for Personalized Medical Care in Pasadena
I am Dr. John K. F. de Beixedon, a board-certified internal medicine physician with over 25 years of experience in private practice in Pasadena, California. Since 1998, I have dedicated my career to providing personalized, patient-centered care through concierge medicine, medical weight loss, and advanced aesthetic treatments. My practice integrates cutting-edge technology with individualized attention to address each patient's unique health needs. I completed my medical training at St. George's University School of Medicine and residency at the University of Virginia, with specialized expertise in diabetes and bariatrics. As a trusted medical advisor for ABC News and a featured expert in national media, I combine clinical excellence with accessible, compassionate care.

My concierge medicine model offers extended annual physicals, same-day appointments, and 24/7 direct access to ensure comprehensive health management. My medical weight loss programs utilize science-based approaches tailored to patients' metabolic profiles, hormonal balances, and lifestyle factors. The Evolvex aesthetic treatments I provide deliver non-invasive solutions for fat reduction, muscle toning, and skin tightening. With a commitment to patient education and sustainable health improvements, I prioritize transparency, ethical standards, and evidence-based practices. My practice reflects decades of clinical experience, continuous professional development, and a dedication to helping patients achieve optimal wellness through personalized medical strategies.
