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., Coaatesville, 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 aborist. 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

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
