About HEI

Mission Statement

It is HEI’s corporate goal to provide the highest quality technical services for its clients while finding practical, cost-effective solutions for compliance or liability issues that arise. HEI maintains that corporate commitment to technical excellence while focusing on project details, yet does not lose sight of a client’s “bigger picture”. Attention is always paid to due dates and turn-around times for all projects undertaken. HEI promotes a proactive approach to regulatory compliance which has proven to result in both economic and operational benefits to its clients, including the proper definition and management of client liabilities.  Additionally, HEI can provide NYSDEC notice of violation resolution services and guidance for other mandated corrective actions. HEI assumes the role of “client advocate” to provide the best services to meet each client’s specific project needs. We are capable of serving large corporations, but we are also especially proud of the services we have developed specifically for small businesses.
