"Took down 4 trees for in the -13 degree temperatures. Did a wonderful job. Stacked up the "Firewood sized" trunk and branches, cleaned up and removed the small branches and twigs in 13 - 14 inches of snow. Did it all in about 5 hours total at a very reasonable price."

"Dean returned my call and I described the small tree I wanted removed. I also sent him pictures. He gave me a price and removed the tree the next day. He is very knowledgeable regarding the possibility of tree roots near pipes and removed the tree and roots quickly. He also cleaned up the area afterwards. Excellent communication, very professional and got the job done! I would definitely recommend him for tree removals!"

"We have used Sergio Ordaz for a long time, since around 2016. He greatly helped us maintain a 30 acre parcel (in zip code 53092) for 7 years, and our current 1 acre parcel (53080) for 3 years. In that time, he has: 1) maintained the yard(s) and garden(s). 2) trimmed trees and shrubs 3) removed trees and shrubs, including a very large area on a steep bank 4) planted well over 1,000 trees bought from the county (plant, mat, tube and stake) 5) built a 200' long retaining wall, that is approximately 10' high 6) plowed our driveway 7) winter/spring clean up 8) tilled and installed a 1500 sq ft native garden We cannot recommend Sergio enough. He can and will do anything outdoors, and I am certain that I left out many of the projects he did for us over the years. Plus, he is great guy; very honest, dependable and has a great sense of humor."

"I reached out to Ryan after the last storm for a tree down. Due to the fact that it was a shared drive, Ryan did not hesitate to squeeze me in. Ryan and his crew removed the fallen tree and a couple questionable ones that would probably have fallen with the next storm. They did an awesome job, in a timely matter and cleaned up so well you never would know the mess that they arrived to. They all were very friendly and personable. I would recommend them to anyone!! This was not the first time the crew did work for me and some surrounding neighbors and we have all been happy with a job well done, so appreciate you Ryan, and your crew. Thanks ~ Christeen"

"The price was very fair. They removed 6 age old bushes that had been in the ground for decades in one hour, c;leaned everything up and planted six new healthy boxwood plants. We were very satisfied with the price, their swiftness in completing the job and their friendly manner. Recommended them to our neighborhood association ."
