These folks are so professional, on time and reasonably priced. I found them online this Spring when we had some major landscaping done in our yard and several mature trees were attacked by the infamous tent caterpillars (those things devour everything in their path!). RTEC came in, analyzed the issue, and even did some work for free on a tree we didn't notice had same issues. I give them two thumbs up in addition to the 5 star rating!
