About Us



Our mission is to promote the highest standards in vision care through quality education, political action, and public awareness.

Our Story

The San Joaquin Valley is large. SJOS serves doctors from Lodi to Turlock. We believe we share common issues and challenges practicing in the central valley and it's nice to meet with other doctors to talk about issues.

Meet the Board

Our SJOS board consists of doctors just like you.

They come from many practice settings.

The only thing they have in common is their desire to make the profession better.
