These guys were prompt and professional, from coming for the estimate, to scheduling the service, and then to doing the work.

For example, the estimator arrived at 9:00 AM, and I mentioned that I was expecting someone at 8:00, based on what I wrote in my calendar. He said that they normally give a window, and that ours was 8 to noon, but he apologized if there was any misunderstanding. In retrospect, I was the one who was mistaken, not him.
The guys who did the work (removing 2 large Leland cypresses trunks) were careful to protect several vulnerable plants and sprinklers underneath. And they cleaned up the driveway mess when done.
Regarding costs, I had an estimate from someone else, who did some other tree removal for me, and that estimate for the this work was 10% higher. Nevertheless, I rated them only 4 stars on Price For Value because I don't really know what these services run. The cost per man-hour for my job came out to around $220-$250, but of course that includes equipment costs and other overhead.
