Derek is the saint of all things TREE! I am not joking. We have used his services MANY times both at our new property and our old.
At the old property, he saved our apple tree, trimmed out of control chinese elm and dealt with a GIANT oak tree that took down our power lines and fence. His team rescued our place during the massive Etobicoke storm in July 2013 (when we had no power) and the Christmas 2013 (when we had no power). Just this past week they did a gorgeous job cleaning up a GIANT maple in our new yard making sure it didn't interfere with power lines etc. My new neighbours liked his work so much they hired him on the spot after watching him work.
Derek is HONEST, he won't sell you services you don't need. He always shows up on time, does the job exceptionally well and leaves no trace. This week the whole family left for work Friday morning and when we returned the giant maple was beautifully trimmed and thinned with no evidence that the team was even here.
Derek is amazing and you will not be sorry you hired him and the team.
