What People Are Saying About Us

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!

By focusing on coastal landscapes and implementing fresh, innovative ideas, I can help create a landscape that is truly unique and tailored to your needs on the northern Oregon Coast. By using cohesive design principles to draft a landscape that works in harmony with your existing living space and understanding the specific challenges of coastal design, I can bring a new vision and new use to your outdoor space. With a strong commitment to sustainable and cutting-edge design and construction techniques, the landscape I will create for you will be a one-of-a-kind, comfortable, and relaxing space to enjoy. With over 20 years of combined construction and design experience, I am well prepared to help you tackle even the most challenging projects.
Sam Defever

Having grown up in the industry, landscape design and construction has been a huge part of my life that I’ve always loved. Graduating from Cal Poly with a degree in horticulture and a concentration in landscape design was an easy choice to make. With a wide array of ideas, themes, and solutions, my passion consists of transforming an outdoor space into a living sanctuary. With my client’s input, wants, and needs, I love creating a unique landscape that will entice homeowners to find peace in this extension of their home. Your landscape should be a representation of who you are as a person. Whether it’s just an installation of a few plants or an entire property remodel, let’s go build something!
Eric Hagberg

I started landscaping in 2004 and have since been fortunate enough to have created hundreds of inspirational designs, improved thousands of beautiful landscapes, and experienced countless wonderful memories and friendships. Over the years, I’ve discovered that a landscape can be a beautiful, evolving puzzle that is an extension of the home and of the lives of the people who experience it. I’ve also found that most people know what they like about a landscape but are unsure where to begin and how to fit all the pieces together—that’s where I come in! I combine your goals and dreams with my experience and trained eye to combine those pieces in a personal way that has form, flow, and function, ensuring that the process is enjoyable, and that the outcome is beyond what you imagine!
Lars Nielsen

My design philosophy is simple. It revolves around my clients’ needs and wants. I incorporate my expertise and present ideas that the client may not even realize are possible, adding personal touches to create a unique landscape design that is as functional as it is beautiful. I achieve this result through open conversation; by listening to my clients and by offering suggestions. I feel that designers often get too wrapped up in their own creation. Instead, my goal is to bring my clients’ ideas to life, using my tools and experience to help them achieve the result they desire; it is my job to look beyond boundaries and find what best matches their objectives. I take joy in a diverse range of design styles, from ultra-modern to traditional Japanese.
Kelly Paxton

My position with Dennis’ 7 Dees started in the field—I spent several years working with a crew to bring to life all the beautiful designs that I now put together myself. I’ve had the pleasure of working with most of the designers on our team, and I feel that what I bring to the table is a little inspiration from each and every one of them. The transformation of a “Before & After” is why I love this job so much!
Drew Snodgrass

Over 40 years in the landscape business have gained me so much to share with clients who desire creative problem-solving and practical, enjoyable, and beautiful landscaping improvements. I’ve won 25 awards to date for my project designs. Whether you want an award-winning project or have a specific need, my goal is your total satisfaction.
Kenna Hartman

I have been a part of the landscape industry for over 25 years. I began as a concrete paver installer. In that time, I became a nationally certified paver installer, permeable paver installer, and a nationally certified segmental retaining wall installer. Though most of my background is in “hardscaping”, I’ve always had a vision of how the entire landscape will develop into a balance of function and aesthetics. I believe that the space should dictate the design based on wants, needs, and budget. The remaining space should speak to you on its use of form, balance, and style. Ultimately, your outdoor space should be an extension of you.
Austin Kelly

As a designer, I take pride in educating and introducing people to a new world that they potentially have never been exposed to. My goal is to ensure that your landscape is not only a reflection of good planning and design, but a reflection of yourself as well. There is nothing like helping people transform their properties from the place they live into the place they call home. Landscape design has been a passion of mine since I was 14 years old. I started with my parents’ landscape, mowing lawns, and working with small hometown landscape companies, and I decided that this was the life for me! I graduated with a Bachelors in Horticulture, Design, and Contracting. It is true what they say: “If you love what you do, you will never work a day in your life!”
Justin Snodgrass

Through my lifelong exposure to the landscaping industry, I have gained a keen interest as well as longtime experience. Over the years, I have been a maintenance worker, a construction foreman, and a landscaper, and I have also worked in nurseries for most of my life. At this point, I am proud to be a third-generation landscape designer. My goal is to transform your dream into a reality through imagination, innovation, and experience, no matter how large or small the size of your project. I look forward to working with you to create the best possible outcome that fits you, your needs, and your budget.
