“Early this Spring I contacted Paul Donovan to consult on my severely overgrown yard of very mature trees and shrubs. Our lot is huge with nearly 20 trees and countless of shrub: out of control Junipers but Paul promised me he could prune them to look natural and he did! Wonderful! Three Maples had dead branches hanging all over, etc. Thought the would have to come down, but once again, he worked magic and they look terrific.

“My neighbors are happy too! Paul’s passion for his work shows in everything he does and he has an impressive depth of knowledge. I highly recommend his company! He made my out-of-control yard look amazing.”

On Mother's day morning I awakened to a spring storm. Our 100 year old 25 foot tree in our front yard was lost to the storm. It snapped in numerous places and large heavy branches were covering our entire front yard all the way to our driveway.

At 7am we called Donovan Arborists. Within twenty minutes Paul was standing in my front yard assessing the situation. In less than an hour he had his team at my home and before the morning was over he with use of power says had the tree taken down all of the debris cleaned away. The best part was the price was more than reasonable. Their professionalism and courteousness were greatly appreciated. I highly recommend them...I have already told my friends about them..and I will use them again.

"We had a new home built a little over a year ago and we relied upon Donovan Arborists in the selection of trees and shrubs for our landscape plan.  Prior to moving, we also trusted Donovan Arborists in trimming large trees at our former property.  They are very knowledgeable professionals who provide quality products and excellent service.  We highly recommend them for your landscaping needs."

I found Donovan Arborists on Angie's List and gave them a call after having some poor experiences with some larger tree and lawn companies. Paul Donovan called me back the very next day, we talked, and he personally came out to our house to talk through what we wanted to do. Paul gave us great advice about ensuring the health of our existing trees, told us about what trees grow well in our area, and then gave us an estimate on the spot. We had three trees removed, one pruned and fertilized, and four old bushes removed and their roots ground out.

Throughout the process, Paul and his team were great communicators and were always very courteous. On the day of the job, the team worked quickly and cleanly, and left the yard nice and neat. They gave us a nice neat pile of firewood from one of our trees.

If you want personal, well priced service from a company that knows trees and cares about trees, give these guys a try. We liked them so much that we just hired them to plant some fruit trees, and I know we'll call them again for next year's work.

As the story goes, it was 1885 when Baron Walter Von Richthofen, a flamboyant early Denver developer, proclaimed Mayfair “The Beautiful Suburban Town of Denver.” Bordered on the west and east by Monaco Parkway and Eudora Street and on the north and south by Colfax and 6th Avenue, Mayfair, claimed Von Richthofen, was “a healthy alternative to the moral dilemmas of city living.”

While the neighborhood wasn’t officially called Mayfair until post WWII, it’s currently named in the top 6 neighborhoods in the city with the most tree canopy, according to www.city-data.com. And as every tree-owner knows, tree canopy equates to cooler temps in the ‘hood.

There are 16,205 housing units in Mayfair ranging from ranches, high-rise apartment buildings, duplexes, condos, and Tudor mansions, with an average build date of 1953. A healthy number of the trees too average that age.

At the center of Mayfair is the eponymous park. More than a quarter of a century ago, when the park was in the design phase, a discovery was made: The old North Smoky Hill Trail ran right through the park. This legendary highway traversed by American Indians crossing the plains. Today, that path is commemorated by the walkway that follows the path of the old North Smoky Hill Trail. During the first couple of years the park was open, Denver city officials brought a herd of goats in to naturally trim the vegetation.
