About Us

CHP Consultants was started in my mind back in 1993 when I was working at the Oak Ridge National Lab. I had the idea of having a team of experienced consultants who could perform projects on an as needed basis. These consultants would have day jobs, but would be available to help clients with difficult problems that required experienced help. The advantage was that everyone would have access to the top people in any of the many areas of health physics, but only pay for the time they were on the project.

In 2002 when CHP Consultants became a reality, we found that in addition to consulting, there was a need for high quality instrumentation at reasonable cost. We had a very good 2002 and I gave up my day job to operate CHP Consultants full time. Since then our team has grown. We have provided countless clients with superior consulting services at low cost, and have provided millions of dollars in savings to those taking advantage of our instrumentation sales and service.

Since 2002, we have consulted with government agencies, multinational corporations, utilities, and small businesses alike. We have provided instrumentation for hundreds of projects saving our clients millions of dollars. CHP Consultants is a Veteran Owned small business that is still here in Oak Ridge, TN where it all began. Thanks again to all our Clients for their business, and the many Consultants that have teamed with us. We are ready to help with whatever you have in mind.

Sincerely Yours,


Robert J. Gunter, MSc, CHP
