Controlled Environment Management (CEM) has been a pleasure to work with; they are always professional and helpful.  CEM has the answers to our technical questions, helps with understanding compliance topics and they work around our schedule. Their services are excellent.   I recommend them with the highest of recommendations possible.

Children’s Specialty Center of Nevada

I have been facilitating CEM services for over 8 years. CEM has always provided a knowledgeable technician, and the work is first rate. Jeff Raposa, has in many cases for our facilities suggested alternative solutions to an air balancing issue or a bio-safety/fume hood certification issue. And in each case Jeff’s recommendation has been followed and the room or hood has been certified. CEM has come to campus on a day’s notice to repair needed equipment, which is a rare positive attribute in today’s business climate. I would recommend CEM services for any research facility or hospital.

Controlled Environment Management is a pleasure to work with.  The technicians know their stuff and keep me informed and up to date.  I appreciate their professionalism and expertise as well as the excellent service.  I recommend CEM to anybody who needs to have their safety hoods tested, serviced, repaired and/or certified.
