Meet Our Team
A native of Agua Prieta, Lenaiz has been assisting at COREI for the past four years. She enjoys being Dr. Tostado’s second set of hands while he works and seeing first-hand how her efforts help others to feel better. Lenaiz is a proud single mom of two handsome little boys and loves spending time with them and her other family members.
Lupita has been carefully managing the administrative processes at COREI for the past 18 years. She is married to Dr. Tostado and they have three sons: one is a prosthodontist, another is an orthodontist, and the youngest is currently studying business administration. Lupita enjoys reading in her spare time and loves working in COREI’s positive environment.
Leslie is the first friendly face you will see when you walk into COREI. She has been here for about three years, and besides working hard at our practice, she is also working hard towards her degree in English Language teaching at Universidad de Sonora. Leslie loves learning new things and meeting new people. Outside the office, her hobbies include photography, reading, exercising, and spending time with her two dogs, a Bully and a Shih Tzu.
