Dr. Rafael Montalvo
Dr. Montalvo, hailing from Denver, Colorado, embarked on an exciting professional journey before finding his calling as a physician. He obtained his Mechanical Engineering degree from the Colorado School of Mines and worked as a Mechanical Engineer, an Elementary Math and Science teacher, and served as a Student Activities Director at John Jay College of Criminal Justice. He later pursued his medical education at the Latinamerican School of Medicine in La Habana, Cuba. Driven by a desire to blend his scientific knowledge with his passion for education and aiding others, he transitioned to the medical field. After completing his residency in UCLA Santa Monica Family Medicine, he embarked on a fulfilling career as a physician. When not tending to patients, he finds solace by the poolside, indulging in the soothing melodies of Latin jazz.
