Mark is the best salesman I have ever met and I have been in environmental sales for 20+ years. Mark has been working for TRS as a salesman for 4.5 years. Everyone that works for TRS who has had the pleasure of interacting directly with Mark have all told me how impressed they are with Mark's professionalism, his knowledge about environmental technologies, his sales and business acumen, his work ethic, the success that he creates, his commitment as a team player, his positive attitude, and the joy and fun he creates at work.

Dajak supports a unique cadre of investigation and remediation technologies that are useful to my clients’ projects. Mark Kluger supports my projects by first understanding my goals, then by helping me to understand the various applications of each technology, and then by developing a business case perspective that helps me assess short- and long-term benefits. His fundamental insight into the technical details of the technologies he represents makes him a valuable business partner. And Mark’s personable style, technical experience, and business focus are just some of the reasons I enjoy working with him. Plus he is timely with his communications and gives me no reason to pay for caller ID!
