“After receiving proposals from four different companies, we selected Nature’s Guardian for our large-scale tree planting project due to their competitive pricing and strong reputation. Mike Sperber, a highly knowledgeable arborist, was actively involved throughout the process, physically on-site to oversee all aspects of the project, offering valuable insights during planning, and always available for calls or site visits. His hands-on approach and expertise ensured that everything was executed seamlessly. Additionally, he stands behind his work, providing a guarantee that reflects his confidence in the quality of the trees and their long-term success. I highly recommend Nature’s Guardian for anyone looking for professional, detail-oriented, and reliable landscaping and tree services.”

Thank you Mike and Holly.” -N.H., Lynbrook
Dear Mike,
“I wanted to let you know how pleased we are with your work. Our garden was such a success at our big party. The people just felt it was so lush and well cared for. Trees bloomed that hadn’t bloomed in years. We are always so excited to come here and enjoy the beauty of nature.”

“I have employed Nature’s Guardian for the past 20 years and found them to be reliable and responsive to all my horticultural needs; providing lawn mowing and routine ground maintenance as well as special services, planning and planting creative and beautiful beds.
They also are expert arborists, planting trees where needed and caring for existing stands.” -J.H., Sag Harbor
“I’ve been working with Nature’s Guardian for 10 years, and through two homes.
What originally attracted me to Nature’s Guardian was their organic approach. I liked the environmentally friendly outlook on landscaping and lawn care. Mike Sperber has been an outstanding partner in growing and maintaining our outdoor environment. He brings a personal touch to business, and is incredibly responsive when there are issues. I highly recommend Nature’s Guardian.” -J.G., East Hampton
“Natures Guardian has provided landscaping maintenance services for my property in Bridgehampton for the past few years.
Their staff is knowledgeable, professional and considerate and they always perform above and beyond my expectations.
The owner of the company, Mike Sperber, makes several personal appearances each year to inspect the property and make sure that everything is completely perfect. I have worked with a few other landscaping companies, but none of them compare to Natures Guardian.
I highly recommend Natures Guardian to everyone that I know.”-R.P, Bridgehampton
“I found Nature’s Guardian through Dan’s Papers and have to say from the first phone call I was extremely happy. The young lady in the office was courteous and supplied me with an abundance of information about the company.”
“I set up a meeting with the owner Michael and was pleasantly surprised by the enthusiasm and knowledge right from the get go. We talked about putting in some new trees to screen our home from our neighbors and adding in a vegetable garden and some perennials. I received an estimate shortly after and the work began in a reasonable amount of time.
“We are so happy with the trees and can enjoy our back yard again with some privacy. We would recommend this company for all your landscaping needs.”-C.B., Hamptons
“I have been thinking to send Nature’ Guardian an email to thank you so much for taking care of the tree next to our house!!! What a wonderful job you did…and now it was even tested by the storm of the century!
What would I do without all you wonderful people, who have become my friends, while helping me. Thank you.”-G.O., East Hampton
“Organic landscaping company. Owner is quite responsive and accommodating.
Been using this company around 7 years now. Our lawn and gardens are doing very well with the organic approach.
We have a dog and did not want to expose her to chemicals so we went the organic root. LOL. Go Organic!”
-R.R., Southampton
“When Natures Guardian first came to my home, they listened to what I wanted for my yard. They didn’t tell me what they were going to do. We worked together as a team to get the yard I dreamed of.
They are always available to answer all of my questions.
I enjoy making changes and adding to my landscape design and Mike Sperber is always available to walk the yard with me and give me his input. I love to pick his brain about the different plant species growing in my yard.
I am always amazed at the wealth of knowledge Mike has regarding plant names, requirements, diseases, solutions to all types of problems in the yards. His staff is always helpful and informative also.”-R.A., Sag Harbor
“I chose Natures Guardian to do the work on my most recent projects because of the way the business is operated, and the finished product is always top notch.
They have been doing the landscaping for us for several years and the estate is always receiving compliments from guests and neighbors for the way the grounds are maintained.
When we had a large project recently that involved a garden plan that would include the removal and planting of large shrubs and a difficult stone wall to be built, Natures Guardian exceeded our expectations. The work was performed professionally and quickly and came in under budget. They worked with us in the design to make it fit the architecture of the home and the terrain of the property.
Very recently, we had a large tree pruning project to be done that would require us to conform to conservation requirements. Natures Guardian assisted us in the planning of how the job should be done to be aesthetically pleasing and with the health of the trees in mind. The job was completed perfectly, resulting in a view that is enhanced by their skilled tree work and doesn’t show where limbs and trees were removed. A beautiful natural view is what we wanted and that is exactly what Natures Guardian gave us.
They are prompt, courteous and professional and I will continue to use them for this estate.” -P.R., Water Mill
