The Mid Atlantic Environmental Hygiene Resource Center (MEHRC) was founded in 1992 as a program of the University Science Center, a Pennsylvania science and technology corporation owned by 28 colleges, universities and academic centers from three states. Financial and technical supports were provided by the USEPA and the US Public Health Service Division of Federal Occupational Health. MEHRC was the brainchild of Mr. Francis Dougherty of USEPA Region III and Dr. Chin Yang, currently President of P&K Microbiology Services and Chief Technical Officer of Aerotech P&K.

Due to a change in focus, the University Science Center asked P&K to assume coordination of the training programs in November, 2004. One of the main tenets of the transfer was to maintain the original MERHC mission. That mission was to provide the best available expertise of the people in the indoor environmental quality industry to promote independent, scientifically based, objective training courses in the field. P&K remains committed to upholding that promise.

MEHRC is a self supporting group based on fees charged from our courses. Our instructors are leading, practicing IAQ professionals-recognized leaders in the industry-with a wealth of technical and scientific expertise solving IAQ problems. We offer 1 to 5 day short courses for which we provide certificates of training, often offering Continuing Education credits from recognized, scientifically based IAQ professional associations.
