Gregg Loewen has been a video consultant and calibrator for 11 years. He is currently the lead video-standards instructor for THX's video-calibration classes. He is also a part-time police officer at the University of Maine.

Michael Chen is a traffic engineer by education and started to do video calibration in 1995 with a LaserDisc player strictly as a hobby. It became more serious in 2000 when he bought a Philips color analyzer for $5000. (A Display LT at $100 these days would be just as accurate if not more so.)

Michael has been on the Internet helping out enthusiasts since 1995. He has also written many Web articles on calibration techniques and documenting the idiosyncrasies of calibration. A number of these articles ended up in a book on DIY home theater stuff around 2003/4.

Going professional was a natural extension of this work, and he attended the ISF calibration class in 2001 to get that accreditation, although he already knew what he was doing. He started to teach calibration for ISF by 2004/5, and he helped launch the THX calibration class in 2008.

Currently, Michael continues to teach the THX Video Systems Level 1 and 2 classes, which have now expanded to overseas locations. He also continues to calibrate displays for clients in Canada and the USA, and he consults with SpectraCal and created their tutorial videos.
