Microecologies® Team - About Us

"In every endeavor, we strive for perfection, and settle for excellence."
                                                                                                                    -Microecologies' creed

Founded in 1993, Microecologies, Inc. has built a solid reputation among residential clients, property managers, architects, physicians, and attorneys by providing excellence in identifying and solving indoor environmental problems.  During these past 20+ years, we have conducted over 5,000 indoor environmental investigations, including over 3,000 mold inspections and water damage inspections. 

We are experienced in conducting mold inspections and clean-ups for residential clients and commercial clients, including apparel and jewelry manufacturers, auto repair shops, copier repair and print shops, retail stores, distribution centers, construction and renovation projects, arts and entertainment facilities, restaurants, health care facilities, offices, and schools. Our staff works closely with property managers, owners, architects, HVAC engineers, and construction contractors to prevent mold growth and improve indoor air quality in buildings.

We are experts in conducting indoor environmental inspections in response to occupant health complaints (which often include allergies, asthma, chronic sinusitis, and multiple chemical sensitivities), and in identifying and eliminating the environmental exposure factors that are provoking the aforementioned health complaint.  Our job is to identify, evaluate, determine the source of, and eliminate or control the unknown biological, physical, or chemical contaminants that are provoking the health complaint. On many cases, we are recommended by and work closely with our clients’ physicians. Some of our work is the result of OSHA inquiries and regulatory compliance issues.

We are also asked by our clients and their attorneys to appear as an expert witness, and we have an excellent track record in assisting our clients’ attorneys to prevail in legal disputes involving environmental exposure issues. Our Chief Investigator, Bill Sothern, is a Certified Industrial Hygienist and recognized contributor to the NYC Department of Health Guidelines for the Assessment and Remediation of Fungi (Mold) in Indoor Environments, which is widely considered to be a seminal document in the field of mold inspection and remediation. He also co-authored the NYC Housing Preservation and Development’s Mold Inspection and Mold Remediation Protocols and the World Health Organization’s Guidance for New Orleans Area Residents Affected by Hurricane Katrina. In addition, Microecologies’ work has been featured on ABC Nightline, NBC Dateline, the New York Times, in This Old House, and in New York Magazine, where we were awarded Best of New York for our toxic clean-up work. 

Several of our employees are certified, qualified and experienced in all aspects of HVAC mechanical hygiene, air filtration, fresh air and exhaust ventilation, water damage and mold growth issues, lead, asbestos, HAZCOM and respiratory protection, chemical vapor and microbial sampling and analytical methods, and contaminant source identification and control. We have developed an odor and environmental tobacco smoke (ETS) evaluation criteria that include both quantitative and qualitative elements, and Microecologies has worked on numerous projects associated with odor and ETS source identification and has designed and implemented engineering controls to substantially reduce or eliminate odor and ETS problems.

A two-person team that includes a Senior Investigator and our Chief Investigator generally conducts each assigned inspection.  Our reports, carefully and thoughtfully written by the Senior Investigator and thoroughly reviewed by the Chief Investigator, contain only site-specific findings and recommendations and do not contain boilerplate filler material.  Where remediation work is necessary, our reports include a full scope of work, in sufficient detail to be put out for bid to qualified contractors.
