"The pro has been servicing our Mclean property quite well for a couple of years. Our lawn looks good and we are satisfied with the service. The customer service is sometimes underwhelming but it gets the job done at a reasonable cost which is really becoming harder by the day to get."

"This is a combination of a 5 star and a 1 star review for Tree Pros, I figure that averages out to about a 3 star rating - you can decide for yourself. TLDR: They did a great job doing the work they showed up for, but never actually finished the job and ghosted us. THE GOOD: I hired Tree Pros to take down two large Tree of Heavens (Ailanthus), remove a grove of Ailanthus, trim two trees overhanging the house, and trim and treat an Ash tree. One of the Ailathus was very close to the house (overhanging it quite a bit), the other was near the street. They did an excellent job removing both of them. They also did a great job trimming all trees and (I assume) a good job treating the Ash. They treated the Ailanthus stumps with Tordon to stop them from sprouting up more, which worked well. They seemed experienced dealing with Ailanthus... which if you've ever dealt with them, they are a HUGE pain to get rid of (see Tree of ****). Tree Pros' quote was reasonable compared to others I got and they were responsive when scheduling the job. We did run into a bump about a week out from our scheduled date when I asked the city (Englewood) to confirm Tree Pros' insurance status. Tree Pros was not registered with Englewood, and an arborist/company must be to do business within city limits. I informed Tree Pros of the issue and they had it worked out within a couple days and we still hit our target date. Overall, no big complaints here. Their staff are friendly and knowledgeable and they did a good job. THE LESS GOOD: This is where the 1 star review comes in. Part of the quote I received from Tree Pros was to subsequently have the tree stumps ground down- we needed to wait 4-6 weeks to let the Tordon effectively kill the Ailanthus stumps, and they said they'd reach back out to schedule an appointment for stump grinding. They originally cut the trees down on 6/22/2022 and 6/23/2022. Come 8/6/2022 (just over 6 weeks), I hadn't heard anything back from them about scheduling the stump grinding, so I reached out. They emailed me back 2 days later stating they would schedule it. I reached back out August 19 (two weeks later) requesting a status. They got back to me August 20th saying they would schedule it. We called and left a voicemail. No response. Eventually, I gave up and hired a different company to do it, because it seems like Tree Pros doesn't care to finish up the job. That being said, I did not pay up front for the stump grinding, so I'm not out any money on them ghosting me, just a bit of added frustration to an otherwise pretty good experience. So, take my experience for what you will, but I personally don't think it reflects well on a company when they bail on the last part of a job. Given this interaction, I would not hire them again and will not be using them for recurring treatments on my Ash tree or to plant a new tree where one was removed."
