CEM has provided excellent service to our research labs, certifying biosafety cabinets and fume hoods as well as decontaminating refurbished and well-used tissue culture incubators. I’ve worked with CEM for over 6 years at a university, 2 biotech startups and a technology incubator and am very satisfied with their quality work and professional staff. I highly recommend CEM for your controlled environment needs.

Jeff Raposa and his company, Controlled Environment Management, provide efficient and high quality service at an exceptional price! I have employed CEM for the past 3 years to inspect and certify our laboratory equipment. Jeff and his staff are quick, professional, flexible, and always extremely pleasant. Jeff himself sends annual reminders that our fume hoods are due for inspection, and is always readily available for scheduling. It is this type of service that makes Jeff Raposa and CEM an exceptional company to work with. I would highly recommend this company!

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.

CEM has been certifying our cleanrooms since December 2005. CEM brings outstanding customer service and guidance to maintain compliance with current 797 standards. CEM was an extremely valuable resource in the design of our recent cleanroom build out. As the largest home infusion provider in the Southwest, CEM is vital to our daily operations, providing constant updates and guidance to maintain the integrity and quality of our clean room to meet current regulatory standards.

Pharmacy Manager

It is always a pleasure working with CEM. They are very prompt, professional and accommodating.  In addition, the paperwork and follow up they provide are excellent. We have been using their services for years and I highly recommend them!

L. Mckee
Facilities & Site Services Coordinator

Our experience with CEM has been very positive. The service is excellent and timely. Jeff always makes sure we are contacted in time to schedule our hood testing and certification needs and the value was enough for me to use them rather than our company contracted firm. The staff is very professional. I am very pleased with CEM.
