There are not ENOUGH stars to give to this company!!! From my first time meeting the owner (Allan)and discussing my tree removal options (and telling him about my horrible experience with another company who gave me a bid on removing said tree) I have been overwhelmed by his KINDNESS, EXPERTISE and just "going that extra mile" to get this huge gumball tree removed out of my yard. The "crew" showed up PROMPTLY before 9am- and literally worked (took NO BREAKS) until right at 5pm!!! I've NEVER seen a crew actually WORK like these guys did- I was only able to get a few names (Caleb, Forrest) but I have to give a huge shout-out to every single man on that team- even that 17 year old- man did he work! And don't get me started on the STUPENDOUS CLEAN-UP they did!!!!!!! They used some VERY COOL technology in taking this tree down- I had neighbors three streets over coming by to see this feat (and hopefully getting some bids on THEIR trees)- I took quite a few videos but you can go to their website to see much better ones. And last but not least, THE OFFICE WORKERS- AMAZZZZING!!!!! I am here to tell you- you WONT FIND A BETTER COMPANY- ANYWHERE! I very rarely take time out to write a thorough review (because people don't have good work ethics much anymore) but THIS COMPANY- I just can't give them enough accolades!!! And don't even get me started on the VALUE! I'm a single retired- living on SSI- God is GOOD!!- THANK YOU to every single person at OLI !!!!!! read more

Incredible!! Customer service was great from the owner bidding job to the workers doing the job. The last worker refused to leave until i was completely satisfied. Removed over 100 ft sycamore from a area in fenced in yard with garage patios etc. To maneuver around with no damage or mishaps. Took a crane a lift chainsaws etc. They not only cut tree down but cleaned up better then i ever expected. It was expensive but worth every penny if it would of fell(which was just a matter not if , when) could of wiped out my home. Can't thank them enough. Highly recommend this company being a home owner have been ripped off by insurance companies, electricians who robbed me while they were here. Very cautious on letting anyone on my property this company gave me toral peace of mind. For me that is a huge part of my decision making. Thank you allan and his team of workers read more

I had some trees in my front yard come down after a storm and I was anxious to get it cleaned up. Allan came out right away and gave me a very fair quote but was straightforward with me that they were very busy and it may take a few weeks to get to me. After I expressed my desire to get this taken care of immediately, they said they would do what they could. They were there within the week, which was awesome! They did a great job and hauled off months of dead tree limbs that I had piled up as well. I am so appreciative that they were able to squeeze me into their schedule that quickly and would definitely recommend this company to anyone looking for tree services. read more

Five stars isn't enough!!! We can't say enough good things about the work OLI did for us in Florissant, removing two dying trees from our front yard that were threatening to land on our house in the next big storm. They did a knockout job in a matter of hours, had all the right equipment, and everyone's experience and teamwork were amazing to watch! The price they did it for, including stump grinding, was a treemendously good deal!! We recommend them to everybody, and would definitely use them again!!! read more

Excellent value and exceptional crew for all of your tree projects! We requested the trimming of several large tree branches that were hanging over our roof, shed and dumpster. The team was safe, efficient and cleaned up all leftover debris. They were kind, professional and communicated throughout the project until completion. We would highly recommend this family owned business for your commercial needs. They truly have a heart for the community they serve. - Madison County Catholic Charities read more

The first time I called these guys a few years ago everything was great, however this time there were a few hiccups with communication. Had to call after the first day as the crew had missed a few spots to ensure someone would come back. In the end Allan who did the assessment ended up coming back out personally to ensure everything went right and I am very impressed and pleased with the dedication he showed to help take care of the issues. Would absolutely recommend. read more

OLI did some work on my property clearing out a large section of trees. The crew that worked on my property was professional, curtious and kind. Not to mention skillful. They all introduced themselves before starting. Briefly double checked about aspects of the project before starting to make sure I received what I needed done. Completed the project quickly and then followed up with me after they were done to make sure I was satisfied. Great job! read more

Have a very large mature maple tree in front of house that is beautiful and shade producing that I absolutely am trying to protect. OLI was hired to lift it and they did a very good job. Plus they did additional work on several other trees on property. Trimming, shaping plus cutting down others. I was very pleased with the finished product and the professionalism and knowledge of everyone involved. I will use them again and recommend them. read more

Let the facts speak for themselves. The amissouri attorney generals office is investigating their business practices. Channel 4 news in St. Louis has done an investigative report on them. Search Missouri Casenet and type in the companies name and the yrs 2025 and 2026. I dont have to say a word. I would give them no stars if I could read more
