Michael A. Beuerlein holds the American Council for Accredited Certification (ACAC) designations of Council-certified Indoor Environmental Consultant (CIEC) and Council-certified Microbial Remediation Supervisor (CMRS). He received his bachelor of science degree in environmental engineering from the University of Oklahoma.

Beuerlein's approach to indoor air quality is a simple, science-based method that reflects his engineering background and thorough knowledge of moisture issues in buildings. The mold industry, unfortunately, has its share of uninformed practitioners, scare tactics, and unwarranted hype—especially when it comes to the often-cited but frequently misunderstood "toxic black mold." It's important that the professional you hire undergo a rigorous credentialing process such as that of ACAC, the certifying body endorsed by the Indoor Air Quality Association (IAQA).
