My wife and I paid a visit to Tri City Rock for a front yard project. Their selection is more than adequate for what we needed. They were able to deliver our order the same day and on time. Their customer service and pricing will have us coming back to Tri City Rock for future landscaping projects.

Robert walked outisde with us and was full of information of what was ideal for what we were looking for. We never felt rushed or unappreciated. Will DEFINITELY be coming back for all the rock help we need!
