Vern Crow is the founding principal of Dominion's operations. Mr. Crow specializes in industrial hygiene/indoor air quality remediation providing investigation, remediation specifications and oversight, and final clearance testing for local, national, and international companies. He also provides Phase I, II, and III environmental site assessments, hazardous waste management, and emergency response and environmental risk evaluation services. Mr. Crow is a practicing Industrial Hygienist; Certified Indoor Air Quality Professional; AHERA Certified Asbestos Building Inspector, Management Planner, Project Designer, and Contractor Supervisor; and Certified Hazardous Materials Manager.

Over the past 15 years, Mr. Crow has resolved a range of indoor air quality issues including mold, asbestos, radon gas, lead-based paint, and airborne vehicular soot contamination for private and public schools and school districts, commercial building owners, homeowners, hospitals, museums, public agencies, and national insurance companies.

Mr. Crow credits include a post-fire mold investigation for an upscale 53-unit condominium complex that resulted in reducing an initial remediation cost estimate from $2.8 million to $700,000 and the complete remediation of the complex buildings. He also lead a plant pathology investigation for a major insurance company that identified the cause of a wilted lettuce crop to be a plant disease organism rather than a weather-related cause, which resulted in a reduction of the claim amount from $3 million to $500,000. In a cleanup investigation of a 20-year-old underground storage tank (UST) at a local school district, Mr. Crow identified an upstream source for the existing groundwater contamination and verified that onsite thermal destruction was a feasible method of soil remediation, actions that resulted in a reduction of remediation costs from $4 million to $800,000.

Mr. Crow has presented training and information seminars on a range of issues including mold, asbestos, lead-based paints, radon gas, airborne vehicular soot, underground storage tanks, and lead contamination of drinking water due to lead-soldered water holding tanks.

Mr. Crow received his Bachelor of Science degree from Arizona State University in Phoenix, Arizona, in 1970 and is currently perusing a Masters Degree at Arizona State University. He is a member of the American Indoor Air Quality Council, American Industrial Hygiene Association, American Energy Engineers Association, National Air and Waste Management Associations, and Arizona Asbestos Council.
