Testimonials

Over twenty-five years of living on a property which is listed on the National Register of Historic Places, we have worked with about five different tree-care companies in caring for our old tree and plant materials, which have needed much care and restoration. When we discovered the services and expertise of Jack and Kris of Guardian Tree Experts about three years ago, we realized that we had finally found the firm which could give us the broadest range of treatments, with the greatest commitment to working with historic materials and design. Not only have they supported our 80-year-old landscape of trees and shrubs with pruning, fertilization, and winter protection, but they have helped in planting new materials, always with respect for the original, historic context of house and landscape. We have appreciated their knowledge of the biology of trees and shrubs, and what they need to thrive, but we have also been amazed by the level of communication, both in person and by phone and email.

Great customer service. Arrived on time. They were careful not to hurt surrounding property. Removed all debris. Price was competitive. Guardian was professional and knowledgeable. They were easy to contact and follow up was prompt on any messages or emails or phone calls. They advised us on saving two additional large trees rather than suggesting to us to cut them down. I liked this since they were sincere about saving the trees rather than making a quick profit on cutting it down. Showed me they cared about preservation. Also liked the fact that they did not use spikes when climbing trees which avoided additional damage.

The Guardian Tree Experts gentlemen are a pleasure to work with. My husband and I find it so hard to take care of our trees and to understand what their problems are. They are just an email or a call away, to give advice and act upon it in the most professional manner. We appreciate the time they take to explain the work that needs to be done and to prioritize interventions when cost is an issue. We also love the gentle reminders about when to do what. We lead busy lives and feel that it is important to get their expert guidance all along. We highly recommend Guardian Tree Experts!

We needed to get some storm damage fixed and future damage (to our neighbor's house!) prevented. Guardian was prompt, efficient, and friendly at every step, from initial contact to estimate to the actual work. And they were extremely reasonable in terms of cost. Watching Jack's climbing was an added bonus.

I am very happy how the trees have been trimmed. I was not able to come home and see your crew do the work but I heard from the neighbors and they all mentioned how impressed they were with the whole process.

— Marion

Thank you for the job you did and for the quick response and booking. Moses and the team were awesome!

— Tom Reilly / Anne Baetzel

Thanks so much for checking in. I want to thank you and your team for your work. The trees look great, and your team left the site looking good. Thanks for leaving a few branches for firewood! I appreciate your consideration about that. Looking forward to having you back in May to treat the elm.

I needed serious pruning done on a large locust tree in my yard. I'd used another tree service before, but I wasn't thrilled with either their work or their prices, so I asked for on-site estimates from three services. Guardian was my choice, because Brian was clearly so knowledgeable, and he was actually interested in another issue I was having with a smaller tree. Guardian's prices were reasonable too. The crew came yesterday, and I could not have been more pleased. It was the end of the day, but the two certified arborists who did the work were energetic, eager to talk about what they were doing and how and why, and clearly more than competent. When they left, you could not have told that any tree work had been done, despite the fact that they had removed two very large limbs from the locust, as well as a lot of smaller ones. The driveway and yard were immaculate. I will use them again, and I'm happy to recommend them highly.

I needed stumps ground down from 4 large bushes and one small pine tree. They came out exactly when they promised to give an estimate, got the estimate via email to me quickly, it was VERY reasonable, and they squeezed me in and did just a beautiful job. It is hard to get good service these days, and so I appreciate the very professional and thorough job they did, as well as the prompt and courteous service. I highly recommend this company and would definitely do business with them again. Thanks guys!

I recently had some trees removed from my backyard that were in a very difficult spot to reach, due to power lines, fences, garages, and houses. Kris and his crew from Guardian Tree Experts were professional, kind, and just all around wonderful to work with. They got the trees down quickly without any damage to the surrounding structures and they cleaned everything up so well. I would highly recommend them to anyone. The tree looks fantastic. I couldn't be happier! I can tell it's thinner, but you've kept its shape. It's exactly what I was hoping to see. Thanks for the extra cable and thanks for the awesome job. If I know anyone that needs help with a tree, I'll give them your information.

We've hired Mr. Richardson on several occasions, for consultations, tree pruning, and tree removal. He has given us great advice, actually saving us money by advocating patience about one tree infestation that cleared up on its own accord, as he predicted it would. He shows up as scheduled and cleans up after the job is done. My husband and I will definitely be calling Mr. Richardson again to use his services in the future.

— Joan M.

Jack is extremely knowledgeable, skilled, careful, and thorough. He provides excellent clean-up and debris removal. He is not at all hasty to remove or treat trees unnecessarily. He cares deeply about trees and preserving them in the most up to date manner.

After spending years injecting our two magnificent ash trees prominently flanking our front entrance, I had to accept that like many other ashes in the area, these would not make it. Jack and his crew proved to be not only consummate at removing the trees, but shared my love of them and helped me retain enough to anchor the front of the property. Jack was responsible and dependable, always coming when he said he would. He was polite and considerate of our property and cars. His work ethic was excellent; he and his crew worked from dawn to dusk. His rates were reasonable and the job he did couldn't have gone more smoothly, even though these were two of the largest trees in Ann Arbor in a very weakened condition. I highly recommend Guardian Tree Experts!

— Pam T.

The trees and the whole yard look so much better. They did the work quickly for a reasonable price and left the yard absolutely spotless. Incredible job. I would recommend Guardian to everybody.

— Jim T.

— Ben H.

Thanks for your quick, courteous, and professional service! It was a pleasure working with you. Have a great summer.

— Deano S.

If you need some major tree pruning services, these guys are an excellent choice. They are competitive, efficient, professional, and very courteous.

— Michael M.

Thank you for doing the excellent work on my trees!

— Beth M.

Thank you for your kind note of thanks. It is a rare gesture now-a-days. Also, we talked a bit about our cottage tree trimming. We'll give you a call when that time comes. Thanks again for the great and neat tree work.

We were concerned about the health of a large black walnut. We contacted Guardian because they had a good report on Angie's List. Jack was helpful and offered information and options that proved useful. He was generous with his time, walking the entire property to listen to our concerns. He stayed to prepare a clear, detailed quote which allowed us to select our highest priority items, with a clear understanding of what it would take to address the remaining needs within the dictates of our budget. Jack was in touch via email, and his crew returned (as promised) a week later to do the work. They were efficient, safe, and left the yard clean. The tree looks great. The overall shape of the canopy seems refreshed. We expect to have Guardian back in the future for more trimming on other trees, and to fertilize the highest value trees.

— Karen W.

Thanks for coming out so promptly to spray the trees. I'll keep a close eye on the situation and will call if I need more assistance.

— Phil H.

Thanks Jack! It's nice to see these two lovely trees receiving some expert TLC.

— Sally B.

Dave and I really appreciate the quick response to our dilemma. You and your team did a great job!

Extremely knowledgable & respectful of trees & the environment. — Ben H.
