I now have used STP three times - twice because a neighbor insists my trees are blocking his view and once to evaluate trees on another property. I also used them as an expert witness in a court hearing.. Recently, the neighbor reared his complaining head again; work I had done with landscape people simply didn't work out. In any event, STP was here this A.M. on time, did all the work I requested, including work not related to blocking views. The staff was courteous and professional. I recommended them to my neighbor who also used them
