The Executives

Patrick K. Miller, P.E.

Associate Principal Engineer, M.S.

Patrick Miller currently holds the position of Associate Principal Engineer at Olson Engineering, and manages the Nondestructive Testing (NDT) Group. Mr. Miller earned his Bachelor of Science in Civil Engineering, Cum Laude, at Tufts University, Massachusetts, in May 2004, and completed a Masters in Engineering Systems (Civil Specialty) at the Colorado School of Mines in May 2007. He has been with Olson Engineering for 13 years, where he has been involved in nondestructive evaluation (NDE) engineering consulting projects on all types of civil structures, applied research including federally funded studies, and NDT product development for Olson Instruments on systems such as the Olson Resonant Tester (RT-1), Sonic Surface Scanner (S3) and Light Weight Deflectometer (LWD). Mr. Miller has also been involved in client training on all systems that Olson Instruments manufactures, both during in-house seminars and traveling abroad for special projects. Additionally, he has conducted destructive condition assessment investigations to help identify concrete material degradation factors and has been involved in material repair recommendations/designs for concrete infrastructure. Mr. Miller has prepared and presented a number of papers related to NDE of infrastructure, geophysical testing of soils, interferometric testing of rock slopes, and analysis of light weight deflectometers.
