Let me first say, don't trust the reviews on AngiesList. Really, how many legitimate customers of a local tree service can post glowing reviews every couple of days for months on end? Hopefully Yelp screens its reviews better.
I hired Marc in 2010 when he was new in the business. He gave me a great price for a job that included removal of two trees and pruning of several. I was glad I could be on site for the pruning activity as these guys are chop happy and they're clearly not arborists. He also mislead me about a few things, but given the great price I was willing to overlook the details. I referred several customers to Marc (for tree removal only), and one later informed me that she might use him for tree removal again and another who said he absolutely wouldn't hire him again. (Since I wasn't directly involved in those other experiences, I don't think it would be fair for me to comment on them here.)
I called Marc in 2011 for a dead tree removal, and I couldn't get a return call. After several days, I finally reached him and he told me that business was good and that he couldn't justify doing work for people who were looking for a good price. That was after 3 referrals to him. I won't call him or refer him again because he's not trustworthy and is only out to make a buck.
