David and his crews are excellent. I've had them completed redo my irrigation front and backyard as well as trimming my trees on 3-4 occasions. The last time was this past Wednesday! I don't have the before pictures but the after pics show the excellent work that they do! These trees were overgrown as a result of all the rain we had and not being trimmed for two years, and now they can safely grow without fear of damage to my roof or solar panels. read more

We were absolutely thrilled with the work David and his diligent crew did in trimming our Coast Live Oaks. He was recommended to us by another highly respected consulting arborist and both David and his diligent crew exceeded our expectations. On our first visit he surveyed our trees and property so he could offer an accurate quote for the work. We were really impressed that beyond merely pulling the required permits, he also set up a meeting with the City of Glendale Arborist so that she could envision and understand some of the proposed cuts for weight reduction/liability mitigation he was hoping to make. (Side note: I was also impressed that she came out for the meeting on her own time at no expense to us--I didn't realize that was in her job purview & she was lovely.) Once the permitting was good to go, he scheduled us. Because of our location and the challenges of our street, it was not an easy job and took two days as proposed. David and his crew adhered to both the proposed quote and the proposed time estimate, both of which are always appreciated. David is personable, knowledgeable and truly cares about his craft and doing things the right way--he was dedicated to doing the best for our trees, but also concerned for the safety of his crew, which is admirable. His crew proved exceptionally hard working and were also really friendly. As Tree Preservation also provides landscaping and landscape maintenance, we are already planning to have David out a again to attend to sculpting/pruning our garden. I'm so pleased we trusted David with the care and preservation of our beautiful oaks. read more

I have 13 trees of varying size, age and condition on my property and some of the larger ones: Coastal Live Oak, Eucalyptus, Norfolk Pines, Avocado and Orange, desperately needed trimming. But I didn't want just anyone to do the work, it had to be a certified arborist with the proper license, insurances and experience with this type of work. I had already called three other companies, one who didn't bother to call back, one who made an appointment with me but never showed up (I had to take time off work to be at the appointment, so that was very rude), and one who gave me an estimate for the work but never called back to schedule the work! I even asked the owner of a garden supply store for recommendations, but none of those panned out either. Finally, one arborist who I called (who had retired) referred me to David Sims, owner of Tree Preservation, Inc. We set up an appointment for him to come out and estimate the work and (miracle of miracles), he showed up on time and gave me a very reasonable price for the work. Not only did his team show up on time, they worked efficiently, wasting no time setting up their ropes and ladders. They worked diligently for three hours to trim, cut, prune and shape all 7 trees. They had a large truck with a chipper to so there was no wood waste left on the property. They even blew off the driveway after they had finished hauling off all the branches and wood scraps, and left everything neat and clean. I highly recommend Tree Preservation, Inc. to any home owner who needs expert tree trimming for a fair price. read more

Our church hired Tree Preservation & Landscaping to trim a large number of trees on our grounds. David, the owner, was easy to work with and gave us a clear bid. He's a certified arborist and is very knowledgeable about trees. He's concerned not just with the aesthetics but also with the health of the trees. I felt confident that David's company wouldn't do a butcher job, like I sometimes see. We got three bids and selected Tree Preservation. David's crew came out punctually, did a beautiful job, and cleaned up perfectly. Among other tasks, they removed two large dead trees and trimmed a pine that is close to 200 feet tall. We're extremely happy with the results and highly recommend Tree Preservation & Landscaping. Thank you, David and crew! read more

David Sims and his crew are without a doubt the most conscientious tree care BusinessI have worked with. David's crews never cease to amaze me at there precise ability to remove dead trees with out disturbing the surrounding plants. Precarious hillsides do not phase these guys! I live in a very rugged canyon in Hollywood. I highly recommend this highly skilled team of tree surgeons to maintain my property! read more

David and his crews were recommended to us by an arborist after we had had a bad landscape pruning experience with another company. David came to view the property and assess our needs before we scheduled any work. Our first need was sprinkler repair, which David's crew provided with great care to detail and a commitment to solving the issue. Several months later we needed a large tree removed. They did a thorough job removing the tree and the stump, covering the ground so that it did not look bare. Just last week we had the entire property pruned - this involves a wide variety of plants, trees and shrubs. We were very impressed with the work. The crew took time and great detail with their work. If there was any question as to what we wanted, they asked before trimming, while giving thoughtful advice about what would look best. We have been very pleased with each crew that has been here. They were all on time, very skilled, professional and tidy. David does a thorough estimate and stays in good contact with his crews and provides us updates via email as the job progresses. I look forward to working with them again. read more

David and his crew are simply the best! My husband is a forester and has worked with David on several projects. We needed to have some major work done on our large Pine, Cypress and Schefflera trees. David came out, walked the property with us and reviewed everything that needed to be worked on. His team of Victor, Steve and Eduardo did a fantastic job. They arrived promptly on time, were professional, hardworking and patient. They kept us updated on the entire process as it was an all day job. They also cleaned everything up efficiently and the trees look fantastic. Coincidentally our neighbors were also having some tree trimming done. Unfortunately whoever they hired to prune their trees, chose to hack them unevenly and they look terrible. I highly recommend David and Tree Preservation as they are truly experts at what they do! Thank you David! read more

I had such a great experience with David and his crew. David came out and gave the estimate himself. He was very nice and knowledgeable and actually told me I didn't need to trim one of the trees I considered having pruned. He sent the quote the same day and they did the work the following week. Jose and Arnulfo did the work and David came by at one point to check in and make sure everything was going well. Jose was really nice and answered a bunch of my questions. They trimmed three trees and were meticulous and careful. I've had someone here before who sped through the process and broke some branches and made bad cuts, so I was really happy to see that David's team were not only knowledgeable but also cared to make sure the trees will continue to thrive. read more

We are very pleased with the tree trimming of our oaks. We were required to use a city-approved trimmer/arborist. David was was great to work with, and was involved not just at the start of the work but toward the end as well. The crew even cleared the roof/gutters as part of the clean up! Victor and the crew were courteous, no standing around talking, they close gates behind them, little things that speak volumes of their work ethic. They didn't butcher the trees, they're clearly trimmed. We'd use this company again and recommend them without hesitation. read more

I highly recommend David and his friendly crew. They did an awesome job on my overgrown property. Very professional and they know how to get the job done right. Everything looked so beautiful when they were done. Thanks again Tree Preservation Inc.! Kim B. read more

I had a 30' Ficus tree 6' from the front of my house. The tree had pulled up the driveway by 14". Though I hate to kill a tree this tree was too dangerous and destructive to keep. With half of the canopy overhanging my 80 year old tile roof the removal was going to be complex. In 2013 Tree Preservation removed the tree in the most careful and professional manner I'd ever witnessed. I was biting my nails thru the entire process even though it was clear they were skilled beyond my expectations. They removed the tree (to the stump) and chipped all of the branches. Light now pours into my courtyard and the ominous and destructive root system (and tree) is gone. Very well priced along with skill wins every time. read more

David, Victor and the team are amazing. Wish I could post a picture of the great work they do. They arrived promptly on time, were professional, hardworking and knowledgeable. My home is on a 10K lot, has 5 queen palms, 10 or so Giant bird of paradise. Three sides of my lot are completely walled with bougainvillea and assorted vegetation, about 20 feet high. I also have a pool, not one leaf was left inside, they thoroughly cleaned everything up. Would highly recommend Tree Preservation without hesitation!! read more

When we lost a few of our trees due to a fungal infection in the soil, David was able to quickly diagnose the problem and offer a solution for a new type of fungus resistant trees. He got the job done so quickly and the trees are just gorgeous! He also treated the soil to prevent fungal infections in the future. David and Tree Preservation Inc. are amazing!! Their customer service is excellent, work top notch, and we couldn't be happier with our new trees! Highly recommend! read more

What an amazing service David and his team provides. Not only is the work top notch, but they have a great understanding of trees. David will always come out before a job and give you recommendations that always keeps the trees health in mind. You will not be disappointed! read more

I've been using David and his Tree Preservation crew for ten years to keep our corals, Chinese elms, jacarandas, birch and white ash trees in shape. David, Victor and the crew are completely knowledgeable about the needs and habits of our trees and their microclimates. We are admittedly picky about what we want yet David and the crew are always accommodating our requests. Last week, Victor and his team removed several high coral tree branches hovering over our neighbor's house - an amazing process to watch. And the crew always hauls everything away and leaves our property spotless. These guys are the best and I'm fortunate to have them take care of our beloved trees. read more

When I called David to ask him about removing a large eucalyptus tree that had fallen against the house and broken a window, he -- despite being booked for several weeks to come -- agreed to make time the next day to evaluate the situation. He came exactly when he said he would and called right away with information and an estimate. Due to a change in schedule, he was able to put a two-man crew on the job the following day. His men were friendly and professional. They arrived on time, took care of their work efficiently, and cleaned up beautifully when they were done. I was so impressed by David and his men that I plan to use them for semiannual yard maintenance. read more

We needed a large Brazilian Pepper tree and a Night Blooming Jasmine trimmed. Victor and Steve arrived right on the time promised, worked very hard, and did a terrific job. They also cleaned up all of the fallen branches and left the yard as they found it. My wife and I are extremely satisfied with the results. read more

David was recommended to us by a consulting arborist who praised his work. We asked him to take over our tree pruning 5 years ago, and our old, damaged trees are healthier and prettier than they've ever been. He and his crew are conservative, careful, and artistic in their work. They work by hand, even on large trees, and are highly skilled at creating a balanced and beautiful shape. No chainsaws, no butchering, no topping; they really know what they are doing. They are also quiet, professional, and do a thorough cleanup. We've recommended him to many neighbors, and many have asked for his name after seeing our trees. I believe he's the best tree service in Los Angeles. We've also just begun using his maintenance service and so far it is the best we've had. No mow, blow & go, but careful, thorough and knowledgable, as well. All of his guys are easy to communicate with and true pros. We highly recommend Tree Preservation. read more

I've used this company on a couple of big jobs, including a 90 foot Aleppo pine, where I needed to have the tree made safer in high winds and rain, since it's close to my house. David Sims was very helpful in consulting before that job...he even sent one of his top "climbers" to look at the tree and share his thoughts, before i'd actually hired them. They did a great job on the pine, which weathered the recent big storm (Feb 2017) with no damage. They also did very good work on my neighbor's trees , which were very close to my property....they now look good and are not encroaching on my yard. Also David has several times advised that trees I thought needed work were in fact doing just fine and didn't in fact need pruning. For all these reasons I highly recommend Tree Preservation ! read more
