“We've been doing business with Lehman for about thirty years now and I've never considered using another tree care company. After this storm (Hurricane Sandy) I was telling all my friends and neighbors what a great job Lehman did, and now I want to tell you.


The debris is all cleared, the slate roof is repaired and we're getting back to normal, thanks to you, your crew, the crane company, my roofers, and my gardener. Everyone really stepped up to the plate and did their job, but nothing could have been done without your working with the crane.”
