Nist Environmental Service, Inc. saved our client over a million dollars in future fines and clean up efforts. John Nist's company's insight and attention to detail were key in a contract negotiation bid-win over seven other companies. Although we now have our own in house environmental reps on John's advice, we're forever grateful for his expertise. John Nist brings to the table quality, attention to detail and follow-up/follow-through customer service. In our eyes, Nist Environmental is second to none when it comes to the assurance of safe operating conditions and a sense of security. The service Mr. Nist provided in the past and has established the standard operating procedures we value as our insurance policy leading this company into the future. Since we are a public company and can't legally put our name to an endorsement, we unfortunately have to submit this review anonymous and give Nist Environmental Service, Inc. - a FIVE STAR rating. Thank you Nist Environment Service, Inc!
