Let's get to work!

Best Tree company EVER!

Five years ago, after one of our heavy spring snows, I woke up to several downed tree limbs. My tree service Co. put me on a 2 week waiting list. I called Mortensen Tree Service and talked to Mark the owner. He came the next day, and made my trees look beautiful, and better than before. He explained how unique his Company was compared to other tree service providers. Not only is he an Arborist, but he deeply cares about the environment. He believes that pruning trees should look natural, like Mother Nature creates. He also developed an environmentally safe fertilizer for tress and lawns without harmful pesticides. A more balanced and pet safe approach to healthily tress and lawn. I fired my old tree company and started using Marks product on all my trees and lawn. It saved a tree that was suffering from a soil deficiency, and also saved my neighbors trees from Blight in just one season!

Absolutely wonderful

Mortensen Tree Service is fantastic. Mark is very intelligent, hardworking, and can explain everything to me in a language that I can understand. He prunes my trees for me and has been doing it for years. He's very personable, punctual, and an all around great guy to work with. The prices are very reasonable. I have him to thank for keeping my trees in wonderful shape. I've strongly recommended his services to many of my friends.

Best tree service, hands down!

We have known the Mortensens for years and always recommend them to any of our friends and family looking for a quality and trustworthy tree service company. They have trimmed and fertilized our huge blue spruce for years, and we have also hired them to trim/shape/remove various shrubs and bushes, and to completely remove an old cherry tree that was rotting from the inside. They work quickly, are very friendly and informative, and always leave the property looking tidy and well cared for. Would absolutely recommend them!

Mark is very knowledgeable arborist. He has removed several trees for me besides pruning trees all my trees.

Besides the excellent tree work he has done for me I also use Enviro Tree to feed my trees, lawn, flowers and shrubs.

Very good.

Mortensen Tree Service is very good. They have done tree trimming, painting and they fertilize the bottom of my trees. It looks great. They are also very timely. I appreciate their service.
