Oak trees dying

Asked September 8, 2019, 7:10 PM EDT

We have a ton of oak trees that are all dying on our lot near Denton, Tx.
Leaves turn yellow and brown, and it looks like fall.
All of the leaves have very tiny perfect circles on them. I'm trying to figure out what is causing this (pest or disease), and how to stop it. I am attaching pictures.
