My neighbor supplied with lawn clippings for composting.
They did not decompose at all. His lawn is treated by a
commercial lawn care company. Could this be the problem? I'm using a tumbler composter. Other hints for composting would be appreciated.

First of all, I'd be wary of using grass clippings that have been treated with chemical insecticides and fungicides. I don't know if that is why the clippings haven't decomposed, but I would suggest you stay away from treated grass in your compost pile, especially if you plan to use the compost on a vegetable garden. Here are a few tips to help your composting:

In order to work, compost need a few things. Think of them as "colors" of ingredients. You need "Brown"-likedirt, decomposed leaves, ashes, etc.
Then you need "Green" - like that grass you were talking about. It could be any fresh vegetable matter.
Lastly you need WATER. The composting material should be somewhat moist. Not drippy wet..but moist.
You need to have air as well, but your tumbler should probvide that. Hopefully, that mini-course in composting should help!
