Trio Landscaping I am Diana Grundeen, owner and lead designer of Trio Landscaping, LLC. I started Trio with the idea that as my own company, I could be inspiring to more people using my unique approach to the landscape design process. A landscape designer since 1999, plus 4 years experience in garden centers and attending Anoka Technical for my A.A.S. degree I have the experience and passion to provide creative and inspiring landscapes.

Some of my passions include water features, cohesive family spaces, and small urban retreats. Being a certified Nursery and Landscape Professional I will develop your project with a base of Minnesota horticulture knowledge.

Trio Landscaping just completed our front and backyard transformation and we couldn't be happier! Diana is a very intuitive and knowledgeable Landscape designer, and is also budget sensitive. Her Landscaping teams are professional, timely, and provide top notch service! I highly recommend Trio Landscaping!

Trio understood that I wanted to attract pollinators and birds, and accomplished that. They brought in specialists for accent lighting and hardscape. The choices for native plants were spectacular, we have a low-maintenance four season landscape with reduced lawn.

I had a consultation with Diana at Trio for a front slope project. Over the past couple of seasons I've received countless estimates and ideas from other landscapers that I ended up not liking, or the sales reps didn't really invest the time, or they ghosted, and in contrast working with Diana was refreshing. She really listened to my concerns and my likes/dislikes and let that guide our conversation.

I'm very happy with my experience with Trio so far and decided to hire them to create the plan for my project. I can finally be excited about this project and that is priceless.

Diana is smart, friendly, knowledgeable, and a hard-working business owner and landscape designer. I'm grateful to have the opportunity to work with her via her volunteer work at the MN Nursery & Landscape Association.

We LOVE our new patio and fence designed by Trio Landscaping! Diana was easy to work with. She broke the project into "stages" or line items and we chose what we wanted to complete this year, do ourselves, or wait to do another year. Couldn't be happier with the outcome!

My wife and I hired Diana to help us plan out what to do with our South Minneapolis yard. I'm pretty handy and felt confident that I could handle the implementation. However, I was lacking in ideas on how to handle our space. Diana was full of ideas and helpful options. We had a good experience and I have referred Trio Landscaping several times since. Thanks.

We are starting phase 3 of our home landscaping and have thoroughly enjoyed the outcome of the first two. Diana listens to what we are trying to accomplish and then creates outdoor spaces that are not only functional but absolutely beautiful as well. The crews are courteous and our yard was left in great shape even after heavy equipment was used. Thanks Trio!

This was not a great experience. We initially contacted Dianna at the end of May and made an appointment to meet mid June. When she came out we explained that we needed to regrade our backyard due to water flooding into our basement this spring, we needed to rebuild a retaining wall, redo our deck and change location and design, redo window wells and plant a few plants/couple trees around the new deck, we stressed importance of getting it done this summer due to foundation damage and water issues. Dianna said they were all projects that her crews could complete but she was starting to book into August.

She said we needed to put down $400 for her to create designs/plans/estimate and we paid her that night. I called to book follow up to review plans for beginning of Aug and Trio cancelled appt and reschedule for end of August. The designs were not want we asked for, for the deck was larger and $$$ (2.5x the estimate we got elsewhere) and "few" plants were >100.

At that time we declined the deck, made changes to landscaping plans and gave her a deposit 5 days later. I asked for a start date and was told "we are behind due to weather" and she would talk to her crews and let us know in a week, the next week when asked again said give 2-3 more days and never heard. Called and left message again with No return call.

Finally I called Oct 7th she said they were now looking at November and I asked for deposit back and initial $400 design fee as I found another landscaper to do the job, she said she would give deposit back but not $400 design fee. I argued that the design fee was given with understanding that she would deliver a service and she was not able to deliver in a reasonable time period.

She refused to give $400 initial design fee back. Dianne is friendly, seems very knowledgeable regarding landscape design and seems to have a lot of experience but lacks communication and lacks coordination to plan and get projects done.

Recently I purchased my first single family home. Before I had HOAs that handled my needs. My father wouldve helped but now I'm 16 hours away. I saw my neighbors lovely yard that looked something from a Home and Garden catalog. He referred Trio. They got back to me quickly. Quoted some prices and I got approval from my dh. They came over the following week for my written estimates and they listened to my vision.

I had sketched out a plan and also listened to John who came do the estimates. Through our collab we came up with a game plan. We got new grass for front and backyard. Planted a few trees and help us start a garden. Our driveway was deteriorating when we bought our house. The replaced it big enough for our cars to fit and to put a small basketball court.

Most contractors we had dealt with in the past were alway late and did a sloppy job and leaving a mess. I didn't want a rushed job. Within a few days I saw the lovely transformation. Since they did great work on our lawn. We will get our deck renovated in the spring. I will give this company plenty of referrals.

We worked with Diana and her team three years ago to design and build a beautiful backyard paver patio. The results were beautiful! Diana made the entire process easy and stress-free for us. She listened to all of our ideas and developed a plan that met our vision perfectly. We sold our house last summer and the patio and landscaping were huge selling points! We moved and have called Diana for a new design and can't wait! I am posting the before and after pictures from our last house - what a difference it made!

From start to finish this was an amazing experience! Dianna and her crew are the best that is out there. The slogan outdoor living concept to completion is the perfect phrase. The creative mind and design skills this.company has is 5 star. Being involved every step of the way. Our project could not have turned out any better then what the did for us! Thank you will never be enough!

Diana and her team did a fabulous job on our landscaping project. Diana did her magic to our vision and it came out even better than we imagined. It was done it a timely and professional manner. She is easy to communicate with and she has a great passion for her work. We would highly recommend Trio Landscaping.

I couldn't be more pleased with the outcome of the landscaping in our front yard. Diana and her team of experts created a "little bit of heaven" where I now enjoy sitting outside. She truly enhanced the look of our yard adding beauty and value to our home. I highly recommend TRIO for any type of landscaping needs you may have.

Trio Landscaping completed a project in my back yard to fix some problem areas. Water collected there and when I moved my bird feeder, it became a muddy mess in the spring and when it rained. The plan Diana Grundeen presented and eventually completed solved my drainage problem as well as became an attractive wildlife feeding area. She incorporated it into my current gardens and I'm very happy with the new look.

My husband and I wanted to add a small patio and sitting wall to our front yard. Diana's design was just what we envisioned. The workmen were 100% professional and careful not to disturb my existing plantings. I would highly recommend them.

Thanks to Diana for the help on the front porch and garden. After 3 attempts on our own, it is nice to have professional design the most important part of our yard
