I have been using Goliath for years and have always been very happy with their service. Pat is extremely polite, efficient and reliable. He calls every 3 months when we are ready for service and will come over any time in between (no extra charge) if there are any problems. In fact last year we had an issue with fleas (we have a dog), and he came in almost every week until there was no more problem. He is really a pleasure to deal with.
