    Tree Care Testimonials

    Named the Best Tree Removal Company in Maine

    • Client Image

      Tanya and Branden are a rare combination of professionalism and good people. They listen, respond, are punctual, and genuinely care. Their cleanup was exceptional and price very reasonable. I love my trees, so they will be my first call if I need tree work!

      • Marianne K Portland, Maine
    • Client Image

      After we moved into our new home, surrounded by mature trees, a friend referred us to Knotty Arborists. Tanya and Brandon assessed the health of our trees and recommended removing only a few limbs. They worked safely and efficiently, charged exactly what they’d estimated, and left our property looking great. We’ll be using them again, I am sure.

      • Alice R.
    • Client Image

      Tanya and Branden reviewed the scope of the job, gave me a quote, and stuck to that quote. They were efficient and skilled and did a great job cleaning up after the job was done. I was very pleased and actually used them again for a second job a few weeks later.
