Employee Testimonials

“N3B has a unique mix of minds and talents who are enthusiastically dedicated to a single mission. I was new to the Environmental Industry and have learned so much in the past 19 months. Anytime I ask questions (I still have much to learn) they are answered with patience and passion – I can tell my co-workers take pride in their profession and enjoy teaching my curious mind. Additionally, I’ve had many opportunities for professional growth, a promotion and a salary increase to reward my hard work. I see no limit to continued growth here. The support and encouragement of my supervisors motivates and challenges me every day.”

“N3B has turned out to be a great place to work, for me. Everyone has their work to do and every employee is a part of the N3B’s success. All employees are expected to participate and be a part of the reward. The benefits are excellent and the corporation as a whole is a DOE contractor that is like no other. Corporate culture is very family oriented and encourages a good work life balance. N3B has high expectations of its people and the team delivers accordingly.”
