My neighbor hired BTS and I came by to chat. My maple in the front yard hadn’t been pruned it’s about 60’feet tall. They thinned the canopy for snow loading and longevity and my tree has never been happier. Trust these guys and highly recommend them for trees in Boulder!

These guys came to the property where I rent on referral. They worked with the owner on scope of work. They pruned two huge leaning spruce trees for wind control and they look great. They also thick mulched the base of all our trees which were really struggling with drought. They pruned our fruit trees as well and did an amazing job. Would reccmend them 100 percent they were professional and good communicators.

Kryn has taken care of our trees for several years. He is very reliable, reasonable, and cares a lot about Trees! He regularly injects our ash trees and has done a great job, pruning and caring for many large trees on our property. We highly recommend him!

These guys took some leaning pines down at our house in the mountains west of Boulder. These trees were in close proximity of neighboring properties, so it was pretty technical, but they did it with ease, and zero issues at all. They were friendly, professional and did an amazing job! They cut the firewood rounds to length and stacked it for me! Highly recommend them!

I had a fire mitigation assessment done on my property in Boulder and after interviewing several companies, I hired Boulder tree surgeon took care of all of the fire mitigation. They raised all the skirts of my trees and they look great. They also pruned my oaks and my maple and set everything up for a strong future. My trees break limbs all the time and I really feel like hiring these guys is worth it overall keeps the trees alive and saves money in the long run. They did their work in a timely and efficient manner, had excellent and clear pricing and they were a pleasure to have around while they worked. My kids and dog all loved them! I highly recommend them!

Kryn did a get job taking down a tall dead aspen right next to our garage. He climbed the tree, taking limbs down as he went. There was never any risk of the tree falling on the garage using the approach that he took.

Kryn has been my arborist for about four years. He is knowledgeable, easy to work with, and always helps me get the most value for my money. We have a farm with many trees, and Kryn has helped us prune several of them and mitigate leaning hazard trees at a great price. Just last month, he brought out a 50-foot drivable lift, allowing us to mulch the bases of many trees—a huge benefit for our property. Kryn is fantastic, and I can’t recommend him enough if you need someone to take care of your trees.

Kryn saved our beautiful choke cherry tree in our front yard from gummosis (injections and pruning). It was pretty sad with a lot of dead limbs and now its in full bloom (See before and after photos)! Call boulder tree surgeon, they won’t let you down!

BTS took down an entire pine tree, that was very close to my house. I watched Kryn meticulously & safely remove bit by bit, the tree from top to bottom. Appreciated the incredible skill it took. Highly recommended!

I’ve lived in Lafayette for 21 years and love my trees. Boulder Tree Surgeon came highly recommended by a friend, and Kryn and his team did not disappoint. They were thorough and efficient in pruning, diagnosing, and injecting for blight and borer (if needed) all of my trees. My beauties have never been happier! Aside from his tree-climbing and diagnostic skills, Kryn is happy to share his wealth of information on all things tree with you. The biggest thing that BTS did was remove the 60% of my neighbor’s ash that had died of ash borer and inject the tree to revive the 40 percent that’s left living. It looks beautiful! Boulder Tree Surgeon passionately LOVES TREES and is dedicated to supporting them all in leading their best lives! Call them. You will be glad you did.

I have a rental in Boulder with some trees that I haven’t done much with for several years. An apple tree lost its top and some other large limbs, an elm was all over the roof tons of dead branches and a maple tree had a large portion that was dead. Boulder tree surgeon came and filled a rather large sized hole in the apple tree caused by insects, cut all the stubs and sealed them, pruned the tree and injected it with antibiotics for blight as well as additional treatments to help it bounce back. The elm was pruned back from the roof but left plenty of shade for the house. The maple wasn’t getting water and had lost about 1/3 of its bark so he watered it and gave it several treatments to help bring it back. The team of 3 worked all day and did an amazing job. I highly recommend them. No one else would have done all the sealing and treatments to get the trees back to a healthy state for the price quoted. Should have had him come before we lost half the apple and the maple. I’m pretty sure they will bounce back after the care he gave them.

I’ve seen Kryn’s work both from a distance and up close: he’s taken care of the trees on the property where I lived, and I’ve also had the pleasure of working side-by-side with him as a helper. Kryn is knowledgeable, reliable, passionate about trees, personable and communicative with the homeowners, and plainly put, he does good, thorough work without skipping steps. It’s invaluable to have someone to trust like that who gets the job done in a good way. I would definitely recommend his services.
