What People Are Saying About Us

Ashley Nilson

We were looking for a patio installation and landscaping for our very small Portland backyard, but wanted plants that were both low maintenance and would not agitate one of our family member's multiple severe allergies. Our landscaper, Lars, was incredibly communicative throughout the process to ensure our needs were met and he supported us every step of the way. I would highly recommend Dennis' 7 Dees Landscaping, and would hire them again for my next project.

We could not be more happy with the landscape services provided by Dennis' 7 Dees. We have just completed the third project in three years to transform our backyard and patio, and front yard / entry terrace. We have been fortunate to work with the same landscape designer for each project. He is creative, intelligent and fun to work with. His designs are lovely and he is always inclusive of our design input. He is skillful in guiding us to the best solution. The landscape crews are skilled and hard-working. Their attention to detail is amazing and we have had no issues with either hardscape or irrigation installations that have needed correction. The entire team is responsive to our requests and focused on our satisfaction with the process and the end-product. We would highly recommend Dennis 7 Dees Landscaping services.

Let me start with, our positive experience with the Landscape Designer, Austin. He was FANTASTIC, from initial estimates, to finished product. Other contractors just didn't listen to what my budget was, and came in over 2X what my budget was. Austin came in a little over budget, but that was because to do everything I wanted, it was a bit more. But, in working with Austin, he came up with landscape ideas, I never thought of, to help bring everything into budget. Now, let me sing the praises of the crew, that came and did the work. Very professional, and kept the worksite clean and safe. I did not need to say anything to the crew, or to Austin, because the crew did everything to perfection, on time, and in budget. The finished project looks and works EXACTLY as what was presented to me in the drawings. I have NEVER been this happy working with a contractor. Dennis 7 Dees is now my go to landscape contractor!

Prompt thorough service for ground preparation and sod installation. Professional and friendly staff who used precision with the installation and superb clean up. Very pleased.

The whole 7 Dees team was so great to work with from design through construction. Kelly met me at the stone yard to review flagstone options and walk me through the pros and cons of various details. Then Oscar's team did such a great job. They worked quickly (through the rain) and always checked in if they had questions about design or direction. Kelly followed up after to make sure we were happy with everything and even came by and planted a few boxwoods himself that had been a last minute design add. The whole team was knowledgeable and professional throughout. No wonder you see the 7 Dees trucks all over town. These guys know what they're doing.

Austin and Shelina and her team were amazing! They transformed my yard and I love looking out back now! I would highly recommend Dennis7Dees.

We hired 7 Dees for help taking out three massive tree trunks and root systems from trees lost in a winter storm and then they squared off our lawn and have our plants and trees a sprucing up by adding new trees and foliage. Working with them was great - they were on time, hard working, and very respectful of our space. The crew on-site left the yard area clean and tidy each day, and were good at communicating progress and asking questions when necessary. The finished product looks great.

We are very pleased with the results of our landscaping and patio project! Lars really listened to our needs and built the plan around that foundation. I found him friendly, knowledgeable, and easy to work with from beginning to end. His estimated project start was on target. The crew was also professional. Both Lars and Jose took the time to talk to me while on site and answer questions or concerns. Thank you Lars and crew for bringing our dream to life!

From our first meeting with landscape designer Lars Nielsen, we knew we were in good hands. His extensive knowledge of plants and expertise in design were readily apparent. Lars and his crew, from start to finish, were a joy to work with and the finished landscape is world class! Our project came in on budget and on time and we are beyond thrilled with the finished product: a gorgeous Japanese-inspired yard full of spectacular trees and plants, stone pathways, multiple water features and more! Lars and his team exceeded all our expectations. Thank you Lars and Dennis' 7 Dees!
