It looks to me like a live oak -- but there are many different species.

Where is this tree growing? And is this a current photo?.. that is, was it recently photographed?

Looks like live oak, but they are rather uncommon in zone 7A.

If you take take a pic of the entire tree, that would help. Is the tree evergreen?

It could be Darlington oak, but usually their leaves are not curled in around the edges and most are nearly defoliated by this late in the year.

It looks a lot like a Sand Live Oak.

Thanks everyone for your help. Although I live in zone 7a, I'm vacationing at present in Florida where I took the picture of the leaves. So that might help. If you still need picture of the tree, I'll take a picture of it tomorrow during the day.

Well, since this is in Florida, that makes quite a bit of difference. It then could be a sand live oak, as nel5397 said. They have the smaller and turned under leaves.
