“John is a true professional with the highest integrity and professional commitment. John is a natural born leader who was respected and admired by all of his direct reports. John has innate leadership skills that allow him to get the highest loyalty and commitment from his organization. John’s tireless work ethic and top notch technical skills allowed him to foster excellent working relationships with all of his clients(many who followed him to ENSR from previous experience with him). During his tenure with ENSR John proved to be the backbone of the SE Region’s long-term success both with his client groups and employees he was entrusted to lead.

I would recommend John for any project, particularly if he were leading the project. His integrity, commitment to utilization of efficient solutions and his honesty, distinguish him from his peers.”

George Rico,  Market Leader/Owner at StaffingForce (formerly Human Resources Manager, ENSR/AECOM)


“I had the privilege of working with John on RCRA permitting issues when his company and mine operated hazardous waste management facilities together.  John consistently demonstrated thorough understanding of not only the regulations, but the regulatory process.   He had keen insight regarding the impact of various issues on operations, community relations and the business strategy. Having started his career as a regulator, he understood the culture and internal processes of the regulators and maintained excellent contacts within the agencies. John was particularly adept at keeping issues in perspective and maintaining progress in a complex and challenging environment.”

Rex Jameson, Owner at Bayside Business Development, LLC
