Dr. Gisell García Breton is a physician whose mission is to help people restore their health by looking beyond symptoms and uncovering the underlying causes of disease. She believes that the human body has an extraordinary capacity to heal when medicine embraces the whole person—physical, mental, emotional, and spiritual—and combines scientific evidence with compassionate, individualized care.

Dr. García Breton earned her medical degree from the Autonomous University of Baja California, Mexico. As part of her commitment to lifelong learning, she completed a Master’s degree in Clinical Nutrition and Regenerative and Anti-Aging Medicine, earned a Diploma in Functional Medicine from the Academy of Functional Medicine, and became a Diplomate of the International Board of Lifestyle Medicine.

As Medical Director of Sanoviv Medical Institute, Dr. García Breton leads a multidisciplinary team dedicated to delivering personalized, evidence-based healthcare. She helps shape the institution’s clinical vision, promotes excellence in patient care, and fosters a culture of collaboration, innovation, and continuous learning.

For more than a decade, Dr. García Breton has focused her clinical practice on the diagnosis and treatment of Lyme disease and other complex chronic illnesses. She has helped develop a comprehensive approach that integrates advanced diagnostics, lifestyle medicine, clinical nutrition, regenerative therapies, and personalized treatment strategies. Her work is guided by the belief that healing is not simply the absence of disease, but the restoration of vitality, resilience, and quality of life.

Her commitment to advancing medical knowledge is reflected in her academic contributions. Dr. García Breton is the author of the peer-reviewed Springer Nature book chapter Clinical Algorithm and Diagnostic Tools for Lyme Disease, published in the Methods in Molecular Biology series. She has also contributed to Townsend Letter and presented scientific work at the International Lyme and Associated Diseases Society (ILADS) Annual Conference.

Outside of medicine, Dr. García Breton enjoys strength training, hiking, and spending time in nature. She believes that living well begins with caring for the body, cultivating resilience, and maintaining balance in every dimension of health—a philosophy she strives to embody in both her personal and professional life.
