Question
We have had the above tree for about 3 years now and it has been doing very well.  However, recently I noticed yellow leaves mainly on the top of the tree.  In examining the leaves (yellow and green) I noticed they have small brown spots all over them.  Is this going to kill the tree?  Thank you for your help.

Usually, leafspots alone don't have a significant impact on an established tree.  Make sure tree is being water/fertilized well and be sure not damage the bark. Yellowing of the leaves may be an indication of a root/soil problem.  A soil test may be helpful from a nutrient standpoint.

Generally for leafspots, I recommend just raking up and destroying fallen leaves during the winter and before spring gets here.  Many disease/insects can overwinter on fallen leaves.  Raking and destroying these leaves can reduce the incidence of these pests.
