Incredibly Professional and Thorough Arborist Services I hired N&D for an expert arborist report related to a neighbor’s hazardous tree, and I couldn’t be more impressed. The report, completed by Logan, was exceptionally well-documented, clearly written, and grounded in professional expertise—no fluff or bias, just a clear and honest assessment based on facts and observation. Communication was smooth, turnaround was quick, and the invoice was fair and easy to pay online. I appreciated the professionalism from start to finish and will definitely be using them again for a follow-up consultation at another property. Highly recommended for anyone needing a knowledgeable, reliable, and objective arborist. — Anna Denver, CO

We recently had N&D come out to perform work across 6.5 acres and I could not be happier with the results. Their professionalism, quality of work, and overall knowledge and honesty was more than we expected. Nik went above and beyond to ensure we were happy customers. I would highly recommend N&D to anyone and will personally use them again.

Could not be happier with the work that Nik and his crew completed at our property. They were efficient and professional and did an amazing job. 100% would recommend them and will definitely use again.

While we haven't done business with ND tree yet, I was riding my bicycle today and encountered one of their drivers. Extremely patient and courteous, waited the extra 5 seconds for me to get to a safe spot to pass me. I very much appreciate sharing the road with such a conscientious individual!

I recently hired N&D Tree & Crane Service to remove a 100-year-old silver maple from my property, and I couldn’t be more impressed with their service. From start to finish, they were prompt, efficient, and extremely skilled. The team used a crane to safely and carefully remove the tree, which was no small task. Their professionalism and attention to detail were evident throughout the process. The crew was also polite and respectful, taking great care to ensure my property was left in excellent condition after the job was done. I highly recommend this company for anyone looking for expert tree removal services. They exceeded my expectations in every way!

We highly recommend N&D Tree & Crane services! We’ve had the same team out a few times in the past 10 years to manage all of our big trees and they are very courteous, professional and knowledgeable. Plus, they seem to know everything about trees. Our neighbors turned us onto these guys years ago and we’ve consistently had great advice from N&D and we won’t use anyone else.

They did a great job removing several trees for us...some of the trees were in precarious places (leaning on our house). They were thorough and came back to grind a stump even more so it would be flush with our grass. Thanks!

Nik and his crew were excellent. What appeared to us as a very challenging removal of a large tree. These guys made it look easy. We highly recommend them for large tree removal with challenging circumstances. Thank you - well done guys!

We were impacted by the tornado that ripped through Highlands Ranch, CO on 6/22/2023. Our tree was nearly blown down onto our house, but instead was leaning into the house precariously. I was given a recommendation from our normal tree service to call Nik. I spoke with him at 6pm on 6/22 and he was able to get his crane and his crew out to our place just after 8am today (6/23). The tree was out and they were off to the next job in just a few hours. They were personable, professional, knowledgeable, skilled, efficient, and affordable. My family can sleep soundly tonight knowing we and our house are out of danger. We cannot thank Nik and his crew enough!

Nik, Mike and Stephan did a great job for us. We needed a tree removed from our backyard that was over 50 ft tall. They were very knowledgeable and efficient, while also protecting our property. It was incredible to see how they used all their trucks, crane and tools to safely remove our tree. We would highly recommend N&D Tree Services

Nick and his crew arrived at my remote location on time and set immediately to work clearing old grow trees and brush to provide fire mitigation boundaries around the cabin. A relief to have this work completed.

I've used N&D Tree Service for a number of years and they are always top notch. I totally recommend their services.

We've had N&D out to our 40 acre farm in rural Colorado three times over the last couple of years as we were most concerned about fire mitigation. The company has great crews and the heavy equipment to do the job. They've all been on time and work very quickly. The majority of the trees we've had taken down have been chipped, but they neatly cut up (stove length) the trees we wanted to save for our stove. All of the crew are very skilled and practice good safety methods. We highly recommend them.

Nik and his team are great. I used them twice for tree removal and tree trimming. Very professional and well priced.

Nik and his team were fantastic. I got several quotes from different companies and Nik and his crew were priced the best. On the day of the job they showed up on time, walked the trees with me to confirm what was being done and got to work. They trimmed a 40ft tree and removed another that was next to our house and leaning towards the house. They did a great job and were quick as well. They also chipped a bunch of extra branches we had collected from around our property for a minimal fee. I would use them again in a heartbeat and have referred them several time since using them.

I used N&D to trim and remove dead trees. The crew did a great job and cleaned up the yard throughly. My neighbor even asked them to trim some of her trees which they did the following day.

Nik and his crew are always great. I'll be using him in the future no doubt !

NandD tree was easy to work with and they did a great job ! Highly suggest !

Been using Nik and his services for years. Straight up honest guy. Shows up on time, transparent on pricing, and doesn’t leave till the jobs done right.

N&D has help me out tremendously on numerous jobs here in CO. They are responsive, always deliver fair bids, and their work is exceptional. I highly recommend N&D for any tree services.

That have removed several trees for me personally I think four and several in our neighborhood. They have always done a great job and cleanup hardly knew they were there. Their cost have always been very competitive

We have used N&D for years and have been nothing but completely impressed. We will continue to use for years into the future!

I’ve known N&D Tree Service of Parker, CO from my experience with them through my former HOA in Gambel Oaks, SE of Parker. They prices are reasonable, their personnel are professional and safety conscious, they are quick, efficient and clean up when they are done. I just had them remove a 60’ Linden tree in my back yard in Lakewood. With their boom truck, it was all done from the street in front of the house. I heartily endorse them for the most challenging backyard tree removals.

I'm a property manager and have used Nik and his crew several times for various rental properties tree/limb removals. Everything from routine limb removal all the way to dead trees interwoven with power lines and everything in-between. Nik saved me when another tree removal company started work on a project and then disappeared mid-job when they realized it was more complicated than they thought. They do excellent work, take care to not damage property and clean up after the work is completed. Amazing company to work with! I Highly recommend N&D and their team!

The crew came to my house initially to remove a large portion of scrub oak. They did an excellent job, so much so, that I immediately hired them to do additional work planting trees. A month later, they came out and planted several trees in very difficult conditions and were extremely professional. All the work is outstanding and I would not hesitate to recommend them for any size job.

They came out quick to give me and my neighbor a quote. Nik is very professional and clearly knows what he is doing. We got the quote the next day and scheduled the service. (Removal of 3 aspens and 1 maple.). They showed up on time the day we agreed to and got all the trees out with no issues. They took extra time to really clean everything up. We were impressed and would use them again.

I’m an ISA Certified Arborist, so I’m VERY picky about who I hire to do tree work. The N&D team have come through for us now on more than one occasion, performing flawless execution of the removal of large trees. They’ve had professional demeanor, professional equipment and an absolute emphasis on safety. As many stars as I’m allowed to, I’ll give them!

We at Bartlett Tree Experts love working with Nik. He is always reliable, responsive, professional, and delivers excellent service. We highly recommend him.

I have used N&D Tree several times. I find them to be very professional and perform quality work. The price is very reasonable. I will be using them again later this fall.

Nik at N&D Tree is a great guy and he runs a professional service. As another professional in the tree industry, I can vouch for his skills, and I enjoy working on projects with Nik and his crew. The capabilities of his equipment are top notch, and I’m happy to recommend N&D Tree to anyone looking for tree work or a crane/ operator.

The absolute best and most professional company I have ever dealt with. When it comes to down to trees I will never use anyone else11

This company was great to work with. We live in the Pinery and have used them several times. Nick was extremely knowledgeable. I recommend them to anyone who asks!

I’ve used N&D twice to remove large trees , including one that was leaning in towards my deck and roof . Nik was considerate of my time and the urgency of getting this tree removed before it caused any damage. My property was neat and clean with the tree gone when I got home that night. I highly recommend Nik and his crew!

I am a very small tree company, and hired Nik to bring out his crane. Nik went out of his way to make sure everything was done safely and professionally. He has a very team-oriented mentality, and communicates well. He cares a lot about quality and efficiency, and has the equipment to get the job done. I cannot say enough good things about him and how he represents his company. I would not hesitate to recommend him for any tree care needs someone might have!

I was super impressed! Such a nice and polite crew. They worked efficiently and got the job done quickly. Cleaned up after themselves and even helped my neighbor with her tree while they were here. Will definitely be using them again!

I would highly recommend N&D Tree for all of your jobs small or large this is a very reputable, honest company, the owner is very involved from the bids to the completion of the job. They have always been honest trustworthy their employees are very professional and clean up after the job is completed, you won’t find a more quality company to deal with true Professionals!!

Very happy to do business with these guys. They were on time and professional. Loved watching the Knuckle Boom truck remove Cottonwoods.

Nik and his crew are extremely professional, reliable, and can handle any tree no matter the size. I have used Nik on countless occasions for extremely large tree removals, and his experience and quality are unmatched. I highly recommend.

They are friendly and respectful, they do the job that you have requested exactly the way you have requested it to be done. They are fully aware of there surroundings at all times.

Nik and his team did a great job removing a huge tree out of our backyard. They are very efficient and professional, would highly recommend them!!

We hired N&D Tree to remove one tree and trim two others. They were very professional, knew what they were doing and cleaned up afer themselves. I recommended them to some neighbors.

Nik and his team are phenomenal. They cut down two MASSIVE trees at my house that were very tricky to get to. They were on time, did such a good job in a short period of time, cleaned up, we’re professional and reasonably priced.

N&D are one of the best companies to work with in the metro area! They're responsive, reliable and honest at every turn. Nik and his crew removed a massive cottonwood from the back of our house and did so with absolute precision. I would and do recommend them to everyone I know.

Nik and his crew are true professionals and a very well equipped tree service. Easily able to do jobs others can’t. He also works hard to participate in an urban tree recycling program to make sure a lot of the trees he removes are turned into lumber and furniture.

N@D tree came out to remove a large dead willow tree from the side of the house . He was on time, had a great price and has really nice equipment to get the job done safe and fast. The clean up was great also. This was a tree a lot of companies wouldn’t even be able to do. Will use again!

This Outstanding Team has done multiple projects for our commercial and residential associations. They have worked with homeowners too and have built a professional reputation with each of our 1200 community members!! We will continue to use N&D Tree for every project in the future!!

We have worked Nik and his crews for many years. We atJPL Cares have our own commercial landscaping business and almost exclusively use N&D. Nik and his crews are very professional, they get in and get the work done and get out no muss no fuss. I also feel compelled to say that they performed charitable work for our BRINGLIFE INITIATIVES (We offer outdoor service related support to those who are shut in or have special needs.) I have called on Nik personally to support some of these jobs in the past and He has willingly supported our cause on multiple occasions with a joy filled heart, for no charge I might add. I am proud to back this company as I have used them up to 20 times over the last 7 years and am very satisfied. If something is a miss, Nik has personally made it right. Hard to find a company with values these days. Not only do we plan to use N&D tree in the future we recommend them all the time because of their professionalism and quality of work. You will not be disappointed. Jim Lynch JPL Cares
