Testimonials

“In March of 2023, we contracted with Brian to do pruning of our major trees and shrubs in our garden, including a dwarf Japanese maple. I could tell that Brian had excelllent training, as he takes much care in choosing where to take pruning cuts. He has also removed shrubs and moved and replanted other shrubs for us, also doing careful work and diligent clean-up. I highly recommend him.”

“Worked with Brian through the summer of 2023 to update our backyard, which included creating a larger patio, rebuilding two retaining walls, and incorporating NW native plants in our yard. Brian was very easy to communicate with and responsive to my texts and emails. He provided us with two initial design plans, and was happy to work with us to modify them to better suit our needs and stay within our established budget.”

“The work was completed in a timely manner, and Brian was clear about timeline expectations before he began. He was also flexible in changing plans as needed - for example, installing sod sooner than planned, to avoid the mess and inconvenience of a dirt lawn through the summer. Would highly recommend Brian for any and all landscaping needs! Thanks and hope all is well!”
