Jim, good pressure treated poles will last a long time with or without concrete.I have not had good luck with cementing poles or posts in the ground. I know it is done a lot, but I have never seen the posts last that way.
A utility company has access to creosote wraps that go around the pole. These wraps prevent rot at the surface and extend the life of a used pole buy a long time.
You make a big bloc of concrete in the ground, sink in it (or bolt) some strong steal like a small beam or two, and bolt on it (them) the pole with a small gap between the butt and the concrete.
The deal is to avoid the contact of soil and water/moisture for the wood pole, allowing the wood to dry quickly after a rain.
You can extend a little the concrete block above the ground like a small pillar ( maybe 14 to 20") to raise the pole over the mud splatter area. It should improve drastically the life's pole.
Wood chalets in the mountains are build on this principle (with stones instead of concrete) and they can last for centuries.
Just make the concrete top nicely flat or with a slight slope to avoid that the water stagnates there.
