Clients
Have to Say

“If I were limited to only one adjective describing this company, I would use the word OUTSTANDING, because that’s what my experience with O’Neill Landscaping Group has been - nothing but simply outstanding with phenomenal service. I did my homework and consulted with several different large landscaping groups in our area to get estimates and ideas for the project in our yard. I decided to go with O’Neill Landscaping Group and could not be more pleased!

From the time I called the company, to setting up the time for the estimate and collaboration, to the final project has been the most seamless and impressive experience that we’ve had in a long long time. Sam Wirth, the representative from the company,  with his acute attention to detail, was in constant communication with me, collaborated, and produced an end result that we could not be happier with!

From the office staff to the workers that completed the project, everyone has been professional, efficient and so friendly. We highly recommend O’Neill Landscaping Group for any of your landscaping projects!”
