  I used Altitude Arborist back in July of 2018 to remove an 80' cottonwood. They did a thorough and complete job in a timely manner - when they said they would. I would recomment to a friend IF Hunter Thowndson is the owner of this company.

  Hunter has been feeding my trees (9) for 4 years. This past year they needed trimming. At first, I was worried about too much trimming, but after a year, I realized it was done correctly. My trees look healthy and great.

  Hired them to remove 3 giant willows from my property. They did a great job and had perfect communication through the whole job. Hunter came out for the estimate and he was a pleasure. Great guy and super knowledgeable! Would  hire again for sure. Thank you crew!
