I had some concerns about Brown spots on the lawn. I must say John was very attentive and concerned about my lawn and explaining to me what he was applying today. He was very knowledgeable. Something I haven’t gotten from Greenlawn in quite a while from the SERVICE people that have come out. i’ve been with Greenlawn over a decade. That’s why I would say he was/is excellent. in the future if John Rivera is available for service in my area, I would request him to service my lawn. To.
