“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.” - Daniela Bidwell

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 Margeson

“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.” - Karen Mikus

“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 Tabbaa

“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 Tobin

“These guys were fast, efficient and they cleaned up everything! They are extremely knowledgable and respectful of trees and the environment, and they did a great job. Good guys at the right price.” - Ben Hubbard

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

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

“Thank you for doing the excellent work on my trees!” - Beth McNally

“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.” - Judy Brent

“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 Wight

“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 Haigh

“Thanks Jack! It’s nice to see these two lovely trees receiving some expert TLC.” - Sally Bund

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