There are several types of galls that form on oak trees. Crown gall on the tree trunk could be a concern. Some are leaf or twig galls formed by mini-wasps to harbor their larvae. They are normally not damaging to the tree. There are usually no known controls and no real need to control. I don't know the oak varieties and common galls on oaks in your area like I do in my home state of California. But you can get local information through your county and univesity extension service, or from a local arborist.
