From the intial contact with Sullivan's till the finished product I found all the staff to be extremely helpful and great to deal with. My Mayday tree is huge and was infected with fungas. The Sullivan staff assessed the situation, left me a great quote that was the best I had received, and returned to do the job as planned. I contacted Sullivan's to question why some branches were left untrimmed. They responded promplty and professionally and were at my home to re-address the situation. They met with me to discuss why some branches were left as well as trim a few additional areas. They also offered great advice for the furure of my very old tree. I will hire them annually and referred them to my three neighbors.
