I have a HUGE OLD TALL tree in my front yard which was definitely not compliant with city regulations for a long time. I had 3 bids.....Mike Olson (Owner of Green Arbor Masters) was the lowest bid. I rescheduled on him at least 4x because I am on a fixed income and had a housemate stop paying rent, drama to get him out.....etc. Mike was SO PATIENT with me even though months had gone by before I had the $ to get the work done. He did a FANTASTIC job!!! I also asked him to blow out my couple of gutters which he did for a reasonable price. I HIGHLY RECOMMEND this company for any tree or shrub needs!!

On March 2nd I and two neighbors received an estimate from Mike Olson of Green Arbor Masters for tree trimming in our yards. All estimates were accepted, and Mr. Olson arrived on March 12th to perform the work. Unfortunately, the work could not be accomplished for one neighbor and completed for me. He advised that he would return on Friday, March 14th to complete the work. Due to inclement weather, he did not return on that day. Since then, until March 17th, we have not heard by either text, email or telephone from Mr. Olson regarding when he would honor his commitment. On March 17th I sent a text to Mike and asked when he would finish. I received a text with him saying "Let me see how tomorrow goes I have a few mood calls with downed trees from the wind." He included two pictures of trees that had been damaged. To date, March 25th, neither my neighbors nor I have received any communication via text, email or telephone any communication from him. In my opinion, his work trimming our trees was good work. However, his actions are rude and unprofessional. read more

Mike, is a hands down incredible arborist and he puts out A+ quality that reflects his knowledge in the industry by always meeting or surpassing industry standers. You will not be disappointed with the end results or the price point. R.M.T.M Association read more

I had Green Arbor Masters cut down one tree in my front yard and trim another in my back yard. Mike proved to be very knowledgeable and thorough. He explained his approach and why and offered suggestions on how I may maintain healthy trees in the future. At completion, the ground was raked and cleaned up. Mike was punctual. He was personable yet professional. I was very pleased with the end result. Quality work at a reasonable price! read more

We had used Mike before and his work was okay. Then when we called again, we had a hard time getting an appointment set. He had lots of excuses as to why he failed to show up. Finally, he assured us he was coming and we were going to be out of town at the time. He asked if I would leave a check with our neighbor, his friend. The neighbor wasn't home so, I left the check between the back door and storm door. He made a special trip to come to our house and pick up the check, and cash it for work he did not do. Never did the work, never gave us our money back. We have called, and called, and emailed with no response. He is a crook! He cannot be trusted. Take your business elsewhere. read more

Terrible business. Do not use. Mike came once, did about half the job, then never came back. I had already paid in full because he was my neighbor's friend, which was my mistake. Lesson learned. There are plenty of other folks out there that do this. Use anyone else. read more

Mike and his team were great. They showed up on time, did quick work and, more importantly, did great work. They removed an old stump I had in my yard, removed two bushes, and sliced up two giant stumps for me that I'm planning to use for a walkway. Mike was very straight forward about communicating what he was planning on doing, and made sure I knew what to expect. They cleaned up well and were in and out in no time. I would definitely recommend Green Arbor Masters and will hire them again in the future. read more

I can't recommend them enough. I have needed some trimming of dead and dangerous branches for far too long, but larger companies (who came highly recommended) gave is quotes then never showed to do the work, changed their quotes on us (by double!), flaked, etc. Mike and his team got it done well, quickly and for a better price than anyone else. He educated me on my tree's needs and communicated well. If you've been meaning to get a tree trimmed or printed, now is the time! Call Mike! read more

Mike came in and gave me a deal because I had been ripped off by another guy that took down my apple tree but never grinded my stump; that I had already paid him for. I referred Mike to my neighbors and they were also extremely happy. He even came out on a Sunday to accommodate my schedule. He really went the extra mile. I highly recommend them! read more

I've had Green Arbor Masters out twice now and both times everyone was friendly and professional, they showed up when they said they would and did GREAT work for a fair price. I will continue to use this business in the future and recommend them to anyone needing help with bushes and trees! If I could give them more stars I would. read more

Mike and his crew provide great service at a reasonable price. Highly recommended. After the monster wind storm in Denver this week Mike had his crew come out the very next day and take care of some snapped branches that were hanging in a large tree over the road. All the neighbors on our block use him for periodic tree trimming and pruning. The job will be done right, no doubt. Justen M. read more

This company just did two tree removals for me. Service was stellar: they showed up on time, they did a great job, and I was particularly impressed that they cleaned up so well, getting all the dead branches that were already on the ground and such. Very reasonable rates. I plan to use them again to plant new replacement trees in the spring. read more

Mike from Green Arbor Masters was very friendly and knowledgeable. He was responsive, stuck to the schedule, and performed the job exactly as we agreed. Very professional. He even offered suggestions on some other landscaping projects I had going on beyond what I hired him for. I highly recommend him and his company. read more

Mike was very responsive and professional when coming to quote our backyard Juniper removal project. The price was very reasonable for the amount of work. Matt did the work and did a good job and was also professional. We'll be using green arbor masters again for our future landscaping needs. read more

I hired Mike to cut down several poplar trees, in which were in tight quarters, Mike and his employee did a great job, will use them again, and very reasonable. And professional. Thanks Mike. read more
