"Excellent job! We had 2 very tall trees trimmed. Everything was done safely and efficiently, and they left our lawn neater than it was before they arrived. They even cut the branches into logs and stacked them for our fire pit. Would highly recommend!"

"Luis and his team in CT (Hartford area) are absolutely outstanding. I do not work for Lars, but I am truly impressed. They removed a maple tree that we damaged and trimmed a large oak tree, and trimmed another maple. Luis is very knowledgeable, and I trust his judgement. He also told me what branches to trim on my magnolia tree. Highly recommend."
