Identifying hazardous tree conditions

When there is a hanging branch or crack in a tree, it's easy to see that a problem exists. However, some issues are more difficult to detect. Simple solutions can make a big difference. Pruning can lessen branch weight and wind resistance. Cables and brace rods can also be effective in helping to limit branch movement and protect trees.

What Our Customers Are Saying

Working with Bartlett Tree Experts was a great experience from beginning to end. Your office staff arranged my appointment. The visit by Giles was informative and very useful. The crew that trimmed two of my trees did an excellent job and left my yard cleaner than when they arrived. I would highly recommend your company.
Don W., Portland, OR

Bartlett was extremely helpful in scheduling the cabling so my sister could watch. They were helpful, cheerful, and willing to answer questions as they worked. Wonderful people and workers. I had three different estimates for this work and am so glad I chose to go with Bartlett.
Diane M., Portland, OR

Very pleased with the professionalism, full service, and expertise from Bartlett from start to finish. Barlett services actually revived and saved a mature Specimen Coast Pine, that we had all but given up hope on. My advice to your potential customers, If you see your trees are waning, deteriorating, don't wait act on it immediately. Let Barlett do an assessment so you know how to proceed. I am now under contract with Barlettt to do regular preventative maintenance. I have already referred you to a client and he will be in touch with you.
Sean K., Lake Oswego, OR

Chase and Jesse did a great job. They were very professional. I will ask for them again for my next job. Drew was also a great help. He knew how the trees should be trimmed and gave me information on future trees that I would like to have trimmed. The bid was affordable for me since I am on a fixed income. Thank you Drew, Chase, and Jesse for a wonderful job.
Janice H., West Linn, OR

We are very happy with the initial visit to the final removal of our tree. Drew was very knowledgeable and helped us with our decision.
Martin S., Happy Valley, OR

We will continue using Bartlett as we continue the massive project to help maintain our many fruit trees. All due to our experience with Russell and the rest of his team.
Mike C., Hillsboro, OR

The arborist and crew members who worked on our project were exceptional. They were extremely knowledgable and communicated everything clearly. The work was done well beyond our expectations, including cleanup. It was evident that safety is a major consideration and that is comforting. We will definitely use them in the future and recommend them to others.
Diane K., West Linn, OR

When onsite, they are personable and willing to share their knowledge. The staff member who treated my Japanese Maple with a fungicide spent time explaining the nature of the disease and the treatment. The staff member who trimmed the Japanese Maples shared his approach to pruning which was heavily weighted on the natural structure of the tree. He pointed out branches that would need to be trimmed in the future based upon the growth pattern of the tree. It was evident to me that this person really loved what he was doing. Those are the types of people that I want working on my trees.
Ramon G., Portland, OR

Brian and all Bartlett staff with whom I have had contact are professional, friendly, and communicate a genuine interest in their work. I trust and value my contact with them and appreciate their services.
Leigh C., Portland, OR

Would like to give a shout out to Bartlett for the extra special care their folks have given to our trees over the years and helping us get through a tough situation recently. Our huge beloved Sweet Gum began experiencing sudden drop of limbs in the heat of summer, even after careful yearly trimmings. Out of concern for neighbors safety, with heavy hearts, we applied for and received a city permit to have it removed. Giles and his team from Bartlett provided both excellent service taking down the tree safely and helping us locate and plant replacement trees to fill the big ugly open space left after our beloved tree's demise. We miss the shade our Sweet Gum provided but our new trees are beautiful and will grow over time, and our neighbors could not be happier to no longer be dealing with the spike ball fruit droppings and the possibility of more branches falling without warning in the summer heat. Thank you, arborist Giles, and your team, for your patient and knowledgeable service, helping us get through all the steps to create such a positive result. We would highly recommend Bartlett, not just for taking down and planting new trees, but even more importantly doing what is needed to keep your trees healthy as they are doing for our sidewalk Maples.
Jan G., Portland, OR

Bartlett Arborist did a very nice job trimming our Oak trees in our yard. Their clean up was fantastic, the yard was left so clean you could not even tell they were there.
Jon and Jane S., Portland, OR

A very professional team. The whole process was very timely from start to finish. I will definitely use again when needed and will let my friends and family know about our great experience. Thank you so much.
Aaron W., Tualatin, OR

Just a quick note to recognize the superior customer service that Kyle Offerdahl and his crew have provided to me over the years at both of my properties in Portland. Kyle and his crew have demonstrated the kind of professionalism that enhances the brand of Bartlett in what appears to be a highly competitive environment. I intend to remain a customer of Bartlett for a long time, and will pass along very good reviews about your firm.
Craig R., Portland, OR

Bartlett provides excellent service and I appreciate the quarterly newsletter, filled with good information for keeping your yard and trees healthy. Every time I have called for service, I have prompt service. Spraying that had been scheduled for spring was completed as promised. I also like the online invoice system, easy to pay and I do not have to wait for an invoice in the mail. Our trees from two years ago to last year is unbelievable, healthy leaves, and doing really well. I am looking forward to the trees blooming this year to see how much healthier they will be.
Cindy R., Happy Valley, OR

The Bartlett staff exceeded all my expectations. Giles came out to look at three of our trees, was courteous, friendly, easy to talk to and he was an excellent listener. Three guys came out to do the actual work and what a team they were. Ben, Michael and Jesus were wonderful, and they seemed to complement one another, which I appreciated so much. I would hire these guys in a minute and recommend them to anyone who was in need of tree work.
Bridget B., Portland, OR

The staff were hard working and respectful. What was promised was delivered. All pruning work exhibited a high degree of skill. Russell Clark is a great representative of Bartlett. He is enthusiastic, professional, understanding, and forward-thinking.
Donna S., Tigard, OR

Russell Clark is always professional and courteous and has an excellent understanding of performing municipal work. He helps to educate our city residents about our tree ordinances and policies. Extremely satisfied with professionalism of entire crew.
Tom S., Tualatin, OR

Everyone was so knowledgeable, courteous, and professional, I felt I was in good hands. Thanks to you and your crew for making a potentially stressful experience so easy for us.
Patty M., Portland, OR

I am thrilled with the work done on my trees. Chase and Jesse listened carefully to what I wanted and did their jobs beautifully. Drew carefully described the work to be done, answered my questions, and promptly sent me a clear proposal. Chase, Jesse, and Drew were all very nice, easy to work with, and conscientious about doing superior work. I will tell my neighbors and will call you again when I need tree work.
Marilou B., Wilsonville, OR

You guys give outstanding customer service. A combination of skilled technical people with exceptional people skills. We recommend you all the time.
Charles, M., Portland, OR

Russell Clark and his crews are timely and efficient. Very easy to schedule, coordinate, and completes our projects as planned. Bartlett is always professional with the residents of our community in Tualatin.
Tom S., Tualatin, OR

Kelsey is the best. Knowledgeable in all areas of tree and yard needs. Kelsey knows I am a widow and sensitive to my budget.
Diane F., Portland, OR

Your staff and services have consistently exceeded my expectations. Do not change a thing.
Lynn W., Newberg, OR

Everyone at Bartlett I interacted with was extremely professional and knowledgeable. Kelsey was so polite and quickly responded to all my questions. When I expressed concerns to Kelsey about one of the trees worked on, he came out personally the next day and took care of it.
Katie, R., Portland, OR

Brian is a pleasure to deal with. I appreciate his speedy response to inquiries and requests and his on-site visits, appraisals, and suggestions of specific services. I am really impressed with the professionalism of crew members. They explain what they are doing and why. They are personable, friendly, fast, and efficient, and they seem to really care about trees.
Leigh C., Portland, OR

This year marks my 30th anniversary of being a Bartlett Tree Experts customer- a very satisfied customer. From my first representative in 1988, Frank McKeever in Raleigh, North Carolina to my current rep., Brian Pickett, here in Salem, Oregon the service, professionalism, and courtesy have always been superb over the years and across the miles…consistently top-quality! If you don’t have Bartlett helping you maintain your property, you’re not realizing the maximum value, beauty and safety of your investment! These folks are simply THE best! the field, the lab, and in the offices.
Jim H., Clackamas, OR

Kyle Offerdahl, our account representative, and Zach Powers, who performs the services, are outstanding. They are both generous with their expertise and time. Their information is current and accurate and we rely on them. We appreciate the years of excellent service first from Collier Arbor Care and now from Bartlett.
Ann A., Portland, OR

Drew Derrick was very professional and knowledgeable. The crew was efficient and cleaned up after the job. We are very satisfied with their work and also with the timeliness of getting the job done. Thank you very much.
Robin Y., Wilsonville, OR

Crew was friendly, well informed, and did a fantastic job. I felt they went above and beyond to do things that conformed to my wishes.
Rebecca Y., Portland, OR

Kyle did a great job as usual. Crew was quick, cordial, and did a great job.
Dan S., Portland, OR

We always appreciate how professional all your people are, no matter what the task. We have always been impressed by the safety procedures followed by your crews, including individuals wearing helmets and eye and ear protection. We like that any high tree work is done using climbing ropes and not spikes. We like that our representative lets us know what needs to be done and also what does not need to be done, very honest and informative.
Marcia P., Portland, OR

I have used Bartlet tree since I moved to Oregon. I have always been pleased with their work. Russell Clark is able to provide service in a timely fashion, he maintains contact throughout a project, and he is responsive to my questions.

Bob and Sue C., Lake Oswego, OR

Entire staff was very professional, will use again.
Bryon, P, Tigard, OR

Kyle Offerdahl does a fantastic job caring for our yard. I can call him with any problem and he responds either that day or the next. He even drops by when in the area to check on the problem instead of just chatting about it over the phone. I truly appreciate his dedication and great service.
Lynne W., Portland, OR

Very knowledgeable on many different topics and friendly.

Susan B., Portland, OR

The team really went above and beyond for us. We now are customers for life.
Tyler C., Vancouver, WA

Logan and his crew were very helpful in restoring our front yard to a near normal state after a massive maple crashed from a storm. Logan was attentive, came out the day after the storm, and was then out the day the debris was removed. The crew was professional, prompt and courteous.
Keith L., West Linn, OR

We could not be more pleased with Drew and his team, they are knowledgeable, professional, and courteous. Our expectations have been exceeded.

A tree fell on our rental during a big snow storm. Logan came out the next day. The tree was removed as soon as possible. We will use Bartlett again before a tree falls.

Very knowledgeable and willing to share information. Extremely helpful and courteous, explaining what needed to be done and would we be ok with what needed to be done! Appreciated that so much, so it wasn't a shock. Definitely needed to be done to correct past tree pruning.
Wayne and Barbara B., Portland, OR

The folks at Barlett have been great. Many thanks for their help and knowledge.

Your Arborist Representative showed up within 30 minutes from when we called. After the giant branches came down from storm damage They did the job the next day, it was fabulous! Highly recommend Bartlett to all our friends and neighbors.
Patty C., Portland, OR

The arborist and pruner did a great job with our trees. I provided a business card and recommendation to our neighbors who just moved into a newly built house next door.
Bill and Rusti G., Portland, Oregon

Knowledgable, with a sense of humor. A nice person.
Margaret B., Portland, Oregon

The highest recommendation I can give the entire crew, Logan, John, and Anthony, is to simply say I insist they all return to service my pruning needs again next year. They are all excellent representatives of your company and the service you provide. None better.
Dennis M., Portland, Oregon

The two crew members were wonderful, fast, and a great team, communicating with gestures and brief statements. I was very impressed when Phil came last year to look at our oak tree and suggested we wait a year for pruning, which we did. I have always told people to go to Collier first (due to my experience and training as a Master Gardener), and am now happy to suggest Bartlett.
Betty B., Portland, Oregon

I still remember the crew who came to trim one of my trees last winter when we were having a sleet and ice storm. I was highly impressed with their fortitude and professionalism. I even suggested they might want to come back on another day, but they persevered. I have always found the staff and Mr. Wich, especially, to be professional and helpful.
Betty M., Portland, Oregon

John and his crew have been coming to my house for years, I think he is the best there is, and it is always a joy to see him and walk the yard with him to discuss pruning. The work you do is superb.
Emily C., Portland, Oregon

Phil is always professional, I can always rely on his recommendations for our trees and shrubs. They look great and healthy. The Bartlett team always pick up after themselves. I highly recommend Phil and Bartlett.
Richard A., Portland, Oregon

Always courteous and on time. Always the best service and products to make my yard look the best in the neighborhood.
Jim, K, Portland, Oregon

The Barlett/Collier crew have all been very helpful. They have provided good advice and treatment on keeping our very old, beautiful Japanese Maple, which suffers verticillium wilt, healthy. We are very grateful for their work on this tree, which offers an amazing canopy for our home and our neighbor's home. They have also treated aphids and thinned our two parking strip lindens, which has also helped their overal health. This team has our thanks and appreciation!
Cindy M., Portland, OR

Logan provided the fullest of information and answered my dozens of questions, and gave me the names (which I yard mapped) of all the major trees and bushes in this beautiful new yard. He also helped assess the dormant compost bin and had helpful suggestions. He willingly adapted things from his original proposal to follow what I was able to have done/pay for this round. We will revisit in the spring!
Sally M., Portland, OR

We have been very pleased and impressed with Logan Collier with his knowledge and professionalism. We have also been very pleased with the various crew members too.
Don and Ladorna S., Portland, OR

Staff and crew members were all very polite and respectful! Thank you!
Toni M., Portland, OR

They arrived on time and did a very nice job.
Mckay N., Portland, OR

Over all a very positive experience, from a live person answering the office phone (very important), to dealing with the sales rep, and the two men who came out and performed the work. A job well done.
David A., Portland, OR

Excellent representative and crew expertise in their work was impressive and efficient.
Tom R., Portland, OR

Everyone listened to what I had to say, and asked me if what was being done to the trees was satisfactory. I appreciated that. Phil, the arborist, was very good. I felt the money charged was fair. There was a lot to be done, and it was done safely, which concerned me very much.
Jan B., Portland, OR

Clinton promptly came over when I called him about a sick looking tree. He diagnosed what was wrong, which was not the usual insect or disease problem. Clint was very knowledgeable, pleasant, and personable.
Elaine F., Portland, OR

I wanted to let you know we're very pleased with the crew's work yesterday. All the trees are vastly improved, even the ghastly sweetgums. But Ashley's work on the big fir out back was truly amazing.
Liz M., Newberg, OR

This is a quick note to express my appreciation for the work done today. Jason and his crew worked pretty steady with care and precision&and had time to give me a few lessons in pruning and tree health. I also enjoyed working with Kyle, who came out several times to do walk through, check on the crew, and discuss future options. Good men, all.
Carolyn W., Portland, OR

Last year, we had our crab apple trees and Mugo Pine and Yew bushes pruned. We were impressed with the talents of the arborists - the pruning of the bushes was skillful and aesthetically pleasing.
Joan H., Portland, OR

We thought the crew was great. They definitely gave us confidence that you-all know what you are doing and that you wanted to cut the trees how we wanted them.
Paul and Megan C., Portland, Oregon

Excellent experience with tree removal. Workers were professional and careful, and the removal area was neat and clean when the job was completed!
Patty S., Portland, OR

We are very happy with our Bartlett team. We have noticed a marked improvement in the condition of our rhododendrons which were infected with the lace leaf bug. They also helped us with our tree pruning.
Doug & Marlene R., Portland, OR

Kyle came and gave us our original quote and returned for a second visit on request on a Sunday afternoon following a storm that did some damage in the area. He was very informative, prompt, and easy to work with. We were very happy with his service!
Eleanor M., Portland, OR

Last week you sent Jason, BK, and Robert to do some tree trimming for me and I want to thank you. They were both personable and professional. Watching BK and Robert dancing around in the tree top, I really think you should charge a fee for that. I have listed you in my file and will recommend you to others. Great job!
Sandra O., Milwaukie, OR

Lyle, Kyle, Nick, Jason and Rowan - all great guys to work with. Knowledgeable and personable. Shannon and Krysta have always been very helpful and polite whenever I've called with questions or needed help. My wife and I are very pleased with our dealings with Bartlett. We know we're in good hands. George and Carol D., Portland, OR

Everyone is professional, courteous, and competent. We have been customers of Bartlett and Collier for close to 20 years and have never been disappointed with the service. Darell P., Portland, OR

When I came home after the scheduled tree maintenance session, I found myself a little irritated because it didn't look like anyone had been here. Only then did I look up into the neatly and cleanly trimmed tree and realize that the place looked so untouched because the crew did such a good job cleaning up. Their pride in their work truly shows. I probably won't need your tree trimming services again, but I will be happy to recommend your business to anyone I know who does. Thank you for doing your job so well. Joaquin S., Portland, OR

These folks are very on top of pointing out problems to me before I was aware of them. This has been quite helpful. Good people. John T., Portland, OR

Thank you for making Lake Oswego Arbor Week 2014 a great success! Over 250 people attended Arbor Week event this year, and over 160 youth participated in an Arbor Day art contest. We couldn't have done it without you. Shannan S., City of Lake Oswego

It seems like we always have time to complain, but never have the time to say anything good. In our case, Val and I would like to express how happy we were with your men, Kelsey and Brian, and the work they did in taking down some very big tree limbs for us. Not only were they friendly, but their work was very professional. Terry and Val M., Portland, OR
