Since 1944, this practice has continuously provided comprehensive vision care services to not only residents of San Diego County but to individuals seeking our care from around the United States and the world. It started with Dr. Amorita Treganza in Lemon Grove. Since then, Dr. Robert Sanet, Drs. Carl and Melissa Hillier have carried on this tradition of helping people overcome visual problems that glasses, contacts and surgery alone can not resolve.
