We have been customers of Ecogen for two years and could not be happier with their services. We are on a quarterly service plan and when we had an ant problem last year they came out three times in a week to ensure that the problem was resolved. It was all covered under the service plan and we haven't seen an ant since then. Today our service was provided by Mark, an Army veteran whose customer service skills are exceptional. He was courteous, knowledgeable and professional, and he is an outstanding ambassador for an outstanding company!
