David Helliar, Arborist Representative

The crew was awesome, Dave explains everything that needs attention. Great job on the trees, thank you.
Charles J., Exton, PA

I am very impressed by the skill and professionalism of the team. David’s expertise helped me in several ways, what needed to be done immediately, what should wait until spring, and what we could leave out. Jim, Zack and Matt were and I do not say this lightly, amazing at what they do. With a team that talented and hard working, I will absolutely be coming back to Bartlett to manage my heavily wooded lot. I am so glad we chose Bartlett. A+ service and results. I give your team five stars.
Mike M., Downingtown, PA

Dave Helliar was very informative.
Kathy R., Downingtown, PA

I wish I could hire you for woodwork on the barn, and fence work, your guys are the best. thank you. So appreciate the professional, responsible staff. you must have a great training program.
Judy H., Honey Brook, PA

Each experience goes smoothly and efficiently.
Mary T., Exton, PA

David Helliar is the best.
Patrick C., Exton, PA

Dave and the crew did an excellent job in the project recommendations, removal, and site cleanup. The two-person team completed the work in less than a day without damaging the surrounding trees or ground. Neighbors were impressed with the in-progress work and requested information on Bartlett as they were looking for a professional service that works safely and efficiently. We will certainly use the service for future pruning and removal of our aging trees.
Dave G., Coatesville, PA

The Tech who came was polite, professional, and trimmed the tree to the perfect shape for it to grow correctly in the space. Thank you.
Donna H., Coatesville, PA

As always, Dave Helliar, with Bartlett Tree Experts provides professional, knowledgeable, and prompt expertise in all areas of tree and plant maintenance. The crews are also of the same caliber. On this particular job Jim and Tim handled my job with superior skills.
Kathy K., Downingtown, PA

Bartlett is a very, very good company all around. Sales, customer service, and operations.
Mike S., Downingtown, PA

The whole experience from start to finish was efficient and professional. Everyone was professional, courteous, and did exactly what they said they would. They were respectful of our property and took great care in keeping it in great shape. Competitive pricing. Certainly would use them again and recommend to others. Great customer care which is hard to find now a days and is not taken for granted.
Jackie S., Exton, PA

David Helliar is an asset to your company. He is so incredibly knowledgeable and knows what needs to be done. David is also extremely personable and professional. Thanks also for having such a great team of workers.
Carol G., Downingtown, PA

Very courteous. Explained what was being done.
Charlotte K., Downingtown, PA

We appreciate the expert consultation and very helpful information. Bartlett has a good reputation in a crowded field, there are many competing tree companies that frequently send us advertisements and offers for their services.
Mark D., Downingtown, PA

Very neat and efficient process.
Christine S., Exton, PA

Your advice on our trees and shrubs over the past three years has been most helpful. All are doing quite well. A current highlight is our Bottlebrush Buckeye planted three years ago. After it was planted, it was experiencing sun scorch in its full sun location. I had not noticed in one of my main sources that it was susceptible. You told me it should improve with age. I protected in part with a large umbrella during 2020-21. This year, it had overgrown the umbrella, and I searched for larger ones. However, I decided to wait and see what happened. What happened is that it is fine. Also, it currently has about two dozen buckeyes.Thanks very much for all of your continued great advice. Hope that your summer is going well.
Bill M., Coatesville, PA

Everyone at Bartlett was very accommodating, ,friendly, and professional. I would recommend them to my friends and family.
Virginia S., Downingtown, PA

Dave and his crew were terrific. On time, communicated, very courteous, left our yard completely cleaned up after completing the work.
Theodore T., Exton, PA

All good and efficient. Knowledgeable and friendly.
Charlotte K., Downingtown, PA

I scheduled the pruning and shaping of a Pear tree next to and hanging over the garage at my parent's house. The work was done to their satisfaction.The three workers can come back anytime to remove additional trees. Thank you for a job well done.
John E., Downingtown, PA

David is extremely responsive and knowledgeable. The crew was courteous and meticulous in their work. Company has been a pleasure to work with all around.
David S., Downingtown, PA

All of my interaction with the Bartlett staff were friendly and professional. Bonnie, in the office, and David, the aborist were understanding and flexible about scheduling around my crazy travel schedule. I was 100% satisfied with the work MIke and Tom the crew members did on the day of the job. When they were done, the trees looked amazing and they left the yard clean of debris. I will absolutely call Bartlett for any future needs and also recommend them to anyone in need of knowledgeable tree service.
Dotty R., Exton, PA

Dave and his team represented among the highest levels of customer service I have experienced. Information was accurate, responses to queries and questions were patiently answered. Answers were clear and where necessary detailed enough for us to make informed decisions quickly. We are novices when it comes to tree care. We are attempting to be educated and proactive stewards of our property, which has specimen trees. I am looking forward to annual events with Dave and Bartlett's professional staff. Thank you for everything esp. the Lark tree experience. My dad is happy.
Cheryl C., Downingtown, PA

David Helliar met with me, walked the property, and made great suggestions. The work done exceeded my expectations.
Chris G., Exton, PA

The crew was very professional and attentive to my questions and instructions. Mike worked the Kwanzaan methodically and patiently. The team worked the two Pines quickly, nice when a crane truck does such quick work. Best part was taking down the Acer Rubrum. The guys were enthusiastic when they arrived and genuinely enjoyed working on it. I enjoyed their chatting after lowering a big limb while one guy on the rope was pulled up off the ground a little, and was telling the guys about another job he worked describing a similar situation. I prefer to use Bartlett for Dave’s knowledge, the professionalism of the workers, and the dependability.
Paula S., Coatesville, PA

Mike was friendly and helpful, cheerfully agreeing to send me a few photos of the Northwood Cemetery tree since it is so difficult for me to get to Downingtown. It was good to see the tree being well taken care of.
Anne T., Downingtown, PA

Dave was recommended and was a pleasure to work with. My appointment was set up in a swift timeframe, and the tech came out the week after I approved the bid. Thank you so much.
Donna C., Coatesville, PA

So nice to work with people who are well trained and communicate clearly.
Judy H., Honey Brook, PA

The crew arrived on time, completed the job as described, cleaned up well. They were courteous and friendly. The manager clearly defined the required work to his crew. I would bring them back for more work as needed.
John B., Coatesville, PA

Outstanding and knowledgeable service from beginning to end. All of my questions were addressed in a professional and courteous manner. Thank you.
Tina W., Coatesville, PA

Dave Helliar and our technician have protected and fertilized our trees and shrubs since we moved into the area over a decade ago. They have always been professional, courteous, knowledgeable, and a pleasure to work with. They have helped us transform a barren new lot into a thriving landscape, and we recommend your services to all of our friends and neighbors.
Jim L., Downingtown, PA

Very informative, patient with my questions, and helpful regarding prioritizing the jobs needed on site.
Deborah S., Coatesville, PA

I've been working with David Helliar for about 15 years now. He has always been extremely professional and a pleasure to work with. Whether I'm just looking for some advice on what to plant or how to care for the trees on my property, he's always knowledgeable and helpful. I have found the pricing has always been competitive if not somewhat less expensive when I've gotten comparable quotes. I'll continue to be a loyal customer.
Brrandi R., Parkesburg, PA

Project manager and crew were knowledgeable, professional, highly skilled, and a pleasure to have working on our property.
June A., Glenmoore, PA

Arborist was great, answered all my questions, and gave practical advice.
Kate F., Downingtown, PA

David and Michael have been wonderful. I have been doing almost everything in the landscape myself for over fifty years, but as the years add up, I expect to ask you to do more and more, because you are great people and do fine work.
Bill M., Coatesville, PA

Five stars to Dave and Mike. Suggestions, explanations, and professionalism was greatly appreciated. Any future tree concerns will be referred to Bartlett. I value my property and appreciate companies who treat my property as if it were their own. Thank you.
Barbara B., Coatesville, PA

David Helliar has been working with us for over fifteen years and has been a tremendous help. I really appreciate all his advice and willingness to come out quickly when we have a significant issue. I have a yard full of great trees thanks to him.
Mike S., Downingtown, PA

Dave and crew were at our house seven years back doing major pruning and thinning on our heavily treed lot. That work stood the test of time, so we were happy to have Dave's guidance on how to handle the removal of a downed tree, and a refresh on our other trees. Bartlett really stands out vs. the competition by sharing their knowledge and care for protecting and extending the life of our trees while also protecting and enhancing the value of our property. Our yard looks great again.
Kevin O., Exton, PA

We have worked with David Helliar many times over the years and he is the best. The crew was great, they let us know each day when they arrived and what they were going to do that day. Thank you for another great job.
Kate H., Downingtown, PA

I wish my experience with other service providers was as great as my experience with Bartlett. From the initial estimate and follow ups with Dave Helliar through completion of the job, everyone was knowledgeable, professional, courteous, and arrival times were prompt. The job was done to my satisfaction and my property was left neat and clean. Highly recommend Dave Helliar and the Bartlett team.
Mike K., Coatesville, PA

Professional and quality work every time.
Judy H., Honey Brook, PA

Dave and Jake were professional, knowledgeable, and courteous.
Vivian C., Coatesville, PA

Dave and the crew did a marvelous job. The weather and the bugs threw us a few curve balls but Dave handled everything. Clean, neat, and priced right. It does not get any better than that.
Wesley M., Coatesville, PA

Service was very professional from my first call. I also did not feel I was being “upsold” as I have experienced from other tree companies when they tour our property. In fact, I was given a couple of easy DIY hints in addition to the services we contracted for.
Susan P., Downingtown, PA

Jason and his crew did exceptional work on Tuesday. The three guys worked smoothly as a team and their expertise and professionalism were evident. Pleasant and courteous, the team demonstrated a commitment to quality work. Every aspect of the job was top-notch, even on a sweltering day in August. This was indeed the A+ Team.
Arlen M., Honey Brook, PA

We have known David Helliar and Bartlett for many years and we have always been pleased with the great work they do.
Sherry R., Downingtown, PA

I called Bartlett after a competitor failed to respond to several calls. Great interaction and responsiveness by the Bartlett office staff. Dave was quick to recognize a serious fast spreading disease on our Blue Spruce specifically and coordinated treatment within hours of his visit. The technician who responded was friendly, professional, and efficient. Great customer service by all.
Ken J., Downingtown, PA

All workers have been very polite, answered any and all questions, and completed their jobs in a timely and neat fasion.
Bonnie M., West Chester, PA

All workers have been very polite, answered any and all questions, and completed their jobs in timely and neat fashion.
Bonnie M., Kennett Square, PA

Dave, our sales rep was very responsive after our call and the crew was polite, efficient, and knowledgeable. Although Bartlett is considered one of the big guys it has a personal small company appeal. In comparison to another local small company, Bartlett's rates were equal or better and approach of projects was non stressful with minimum impact on the property. I would recommend Bartlett to everyone.
Mark S., Glenmoore, PA

Every encounter with all Bartlett's staff has been wonderful.
Kathryn A., Downingtown, PA

A great crew that took on a tough job of bringing down a very tall tree overhanging our house. They got the job done a day-and-a-half earlier than projected, including removal of numerous trash saplings and debris while carefully working around a Japanese Maple we wanted to preserve. I think a key to their work was the pre-work inspections - there were two, the second with the work team foreman, very thorough and identified potential difficulties and worked out plans for dealing with them. As the property owner, I found these inspections reassuring. All of my questions and concerns were addressed to my satisfaction.
Jeanie S., Coatesville, PA

Dave Helliar is an excellent representative for your company. Honest, good communicator, and timely. Everything Dave promised happened! Hard to find these days. The technicians are courteous and the hardest working group of three people I have seen in a long while. I hire contractors regularly at my job but none work as hard as these guys! The job turned out great! Thanks!
Don V., Honey Brook, PA

We have been using Bartlett Tree for our landscaping needs for many years. David Helliar is so knowledgeable and always strives to accommodate our needs in a timely fashion. The young men who did our most recent work were experienced, polite, and did a great job. I always look forward to Bartlett Tree Experts keeping our landscaping looking its best!
Maureen B., West Chester, PA

Dave has always been courteous and professional in all of our dealings. I would recommend Dave to everyone who needs an arborist.
Raymond S., Parkesburg, PA

Dave is professional, courteous, and knowledgeable - a pleasure to interact with and a valuable asset to Bartlett. Dave has been our Bartlett Arborist for many years.
Evelyn H., Downingtown, PA

Dave is always helpful and very pleasant to deal with. The crews that have been to our property are very hard working but still take the time to answer questions when I have them. Very professional all the way around!
Tom D., Devon, PA

Dave Helliar does a great job and works well with the crews.
Bob T., Downingtown, PA

The crew and supervisor David Helliar showed up right at 8 a.m. My wife had worked a night shift, they kindly held off using the chain saw and chipper until late in the day. They worked until almost 7 p.m. cleaning up. All debris carted away. Everything looks great. And no tree damage from when Hurricane Sandy came through. Several other neighbors used competing services and there were a couple of real hack jobs that will require several years to look good again.
Frederick V., Downingtown, PA

Dave and his crew provided great service. The trees that were pruned look beautiful - almost like they weren't pruned! I see many trees around town that look like a hatchet was taken to them. Mine don't look like that thankfully! Thank you for your care!
Mary C., Downingtown, PA

We have used Bartlett for a number of years and have always been pleased and satisfied with their staff as well with their services.
Kathryn A., Downingtown, PA

David Helliar is extremely personable and knowledgeable, prompt, and courteous. I have been satisfied with him and his crews work in the past and will continue to use Bartlett for work that might be needed in the future.
Irene D., Exton, PA

Dave Helliar, our Bartlett Arborist Representative and Mike Schaefer, our "master pruner", work together to keep our landscaping healthy and correctly shaped. We are grateful that Mike noticed a serious problem with our Maple tree in the front of our property and did the necessary work to correct this problem and save this tree. Landscaping is a large investment and we are happy that Dave and Mike show such a professional, educated interest in the care and maintenance of our property.
Maureen B., West Chester, PA

Dave Helliar is a true professional. I know he will always be prompt and knowledgeable about the issues I have regarding my property. When he makes 'seasonal' care recommendations, he always follows up and they are addressed accordingly.
Kathy K., Downingtown, PA

I am always impressed by how knowledgeable all the Bartlett employees are, especially our arborist representative, Dave Helliar. Your employees are always friendly and helpful, including our technician.
Renee F., Unionville, PA

David was prompt for the initial proposal and the work day (actually early, which was great)! He walked through the yard and even provided me a "map" of the yard to show which trees would be addressed--that made it very easy for me to relay info to my husband and that extra touch helped David to win the business. We are very pleased with the tree work done, the yard was left neat, and the guys were very professional and courteous. I always appreciate it when a crew will come over and shake my hand and introduce themselves. They worked hard, David came back to check on the job (as he said he would), and they finished even earlier than expected. We are very pleased & our yard looks much nicer now!
Karen L., West Chester, PA

I am always impressed by how knowledgeable all the Bartlett employees are, especially our arborist representative, Dave Helliar. Your employees are always friendly and helpful, including our technician.
Renee F., Kennett Square, PA

Hi Dave, Just a quick note to tell you how pleased we were with the work your company performed on our property. I was especially pleased when the two flowering crab apples you pruned came into bloom. They were really spectacular and their shape is so improved. Thanks again and I look forward to working with Bartlett again soon.
Bill M., Downingtown, PA

Dave Helliar is always great - he communicates well, takes his time to explain things, and I have never had to chase him around, he always returns my calls promptly. The crews that have been to our home are hard working and will stop and answer questions with hesitation. Bartlett is not inexpensive but I wouldn't change companies for anything.
Tom D., Devon, PA

I am a return customer to Bartlett and a big fan of David Helliar and have only great things to say about the firm and the service.
Lois C., Downingtown, PA

Dave and Mike are the best! I feel very confident leaving the care of my trees and shrubs in their hands.
Maureen B., Downingtown, PA
