A foreign medical graduate from Ciudad Juarez, Mexico, Dr. Tristan did her pediatric residency at Brackenridge Hospital/Children’s Hospital of Austin (Texas). She has lived in Imperial County for 17 years where, through close collaboration with the local health department, she has provided nutrition education to children who attend the Wellness 4 Kids program in Calexico. Wellness 4 Kids offers nutrition and physical activity services to children ages 2-18 with a BMI > 85%. Dr. Tristan is currently the program’s Medical Director. Besides chronic disease, Calexico and neighboring Mexicali – in fact, much of the Imperial Valley – have very high levels of air pollution. Dr. Tristan’s areas of interest, therefore, include pediatric asthma and obesity. In addition to Wellness 4 Kids, she has worked with the Imperial Valley Child Asthma Program at El Centro Regional Medical Center.
