Aside from Cal’s many years of experience, he brings a professional development (PD) history and his own technical research on many aspects of this complex field.  The PD and research has allowed Cal to develop many relationships with highly renowned peer professionals including EPA contacts.  Cal presents his PD / research in professional papers to his peers and to those of interest at conferences throughout US and Canada.  Calvin has been involved in several educational venues teaching the fundamentals of air pollution, air pollution control, and the testing of air pollution.


Calvin's project management experience spans a wide range of industry throughout many states in the U.S.  These projects are as small as testing an asphaltic hot plant to as large as a multi-source facility wide testing campaign and hazardous waste trial burns. Calvin has been a CEM integration manager for both replacement CEMs and newly installed CEMs.  Calvin has also been involved in combustion optimization projects on natural gas burners/engines, lime & cement kilns, hogged fuel boilers, and dust burners.
