Carl went out of his way to accommodate us despite his very busy workload; he understood we needed answers before committing to rent the apartment. He was friendly, very professional, arrived on time for the appointment, and completed the air quality indoor testing in the time he indicated it would take.

A-1 Certified Environmental, Carl, a mold specialist. He was incredibly helpful, consistant, professional, prompt, informative and honest. He was personable and I felt safe having him in my home. I stumbled on your website while looking for a mold specialist and he is an asset to your establishment.
