Denny D., Doylestown

We have known Bob and Dave for years. They both have a keen interest in seeing that whatever work we needed done was done professionally and as we requested. The crews that did work at our home were courteous, conscientious and respectful of protecting other trees, shrubs or structures near the work site. We highly recommend them for all your tree work and other landscape needs.

Bob and Maryann R., Doylestown

We have been with Keystone Tree Experts for over 25 years and receive nothing but courteous service from all their employees. We have never lost any shrubs or trees over that time. Any concerns we have are responded to immediately by Dave Ferrier. We highly recommend Keystone to keep your shrubbery and trees healthy.

Barry W., Newtown

We've been long time very satisfied customers. Excellent service and valuable advice.

Jeanne H., Doylestown

We have used Keystone Tree Experts for 15 years. We live on four acres of deciduous trees that require maintenance for safety and beauty. Twice each year, with the exception the nasty storms within those years, Herb Hickmott has assisted us with his amazing knowledge of the forest. When a storm arrives and there are no problems we know he did his job well in advance.

Having property with trees doesn't mean you call when a tree needs to come down or only when a tree fell and needs to be removed. It means caring for the beauty that surrounds you with a team of professionals, tried and true through the years. We would highly recommend Herb and Keystone Tree Experts!

Else K., Yardley

My trees have been taking care of by Keystone tree for the last 15 years. I have been very pleased by the individual service they have provided, their knowledge and expertise. I can't say enough good about them I would highly recommend them. My trees and bushes have been in good hands.

Joanne M., Doylestown

We have been working with Herb Hickmott for over ten years. There is NO ONE we would trust more than Herb. Not only does he arrange for the removal and trimming services we need; but, he gives wonderful advice and educates us too. When we have a problem, I’m so relieved that I can email Herb and know that he will help us in the best way possible. Thanks Herb!!

Joan Y., Washington Crossing

We have been Keystone customers for at least 7 years. The customer service is superb. Each call or email was promptly answered. Each visit for fertilization or tree trimming was performed by professional, friendly and knowledgeable staff. They don't push unnecessary treatments and offer advice to help us keep healthy , happy trees and shrubs on our own. We have been told by neighbors and "walkers" our property is beautiful and we owe a lot of that to Keystone. We will continue to be happy and grateful customers for a long time!

Brian and Patti P., Doylestown

For close to 40 years, we have depended on the expertise of Keystone Trees to keep us safe. They have pruned trees so that if the tree fell there would be no contact with any buildings or wires. Our shrubs are thriving due to maintenance recommended by Keystone. And, in times of emergency, they have responded within hours to address the issue. Keystone Tree, people you can depend on.

Martha M., Doylestown

We have used Keystone Tree for twenty-four years. They are outstandingly knowledgeable, safety-conscious and reasonably priced. I cannot recommend them more highly and I often do recommend them!

Deborah D., Solebury

Keystone Tree Experts have maintained our trees and shrubs for more than 20 years. We have always valued and appreciated the professionalism, expertise, reliability and personalized service provided by Dave Ferrier and the Solebury team.

Jim M., Warminster

I have been working with Keystone Tree Experts for over 20 years and in several different homes and their service is second to none.  I usually meet with Herb Hickmott in the Spring or Fall to look at my property and make sure everything is OK and assure I’m on the right plan to keep everything looking beautiful.  I’ve recently moved to Warminster and have already met with Herb to review my plantings.

Steve H., Doylestown

We have used the services of Keystone Tree Experts for over 40 years. They are an experienced, thoughtful, careful, professional, and responsive provider of tree services.  I recommend them wholeheartedly.


Tom T., Buckingham Township

I have been a customer of Keystone Tree Experts since its founding in 1968. They have helped me with snowstorms, ice storms , and hurricanes but I am especially impressed with Bob McMullins efforts to save our diseased Copper Beech. He has tried several innovative ideas and consulted with Cornell University. The tree is still alive and shading my yard. THANK YOU.

Sandy L. & Susan E., Doylestown Borough

We have used Keystone Tree Experts over the years to remove some large trees from our property. This is usually a complicated task here in the Borough, where they have to work around high wires and fences, and in confined spaces. Keystone starts their day, by showing up when they say they will, both crew and supervisor. They are neat and considerate and we feel secure in the knowledge that they care about our property, and what they are doing.

Sylva S., Furlong

I am very pleased with the service that I receive from Keystone Tree Experts. Dave Ferrier is the Arborist that I contact and my call is promptly returned. Dave, along with the men who work on my property, are always courteous and professional.
