Steven P. Compton Ph. D.

Executive Director


Dr. Compton has assumed Dr. Jim Millette’s responsibilities. Having worked alongside Jim, Steve is well qualified to assist clients needing expertise in the environmental, industrial hygiene and materials science areas. If you have questions regarding a specific project, please call Dr. Compton.

Steve is one of MVA’s Executive Directors and Project Leaders, in charge of client interactions, report writing and review. He is a physicist with experience in materials science, microscopy, industrial hygiene and environmental forensics. He specializes in identification of unknown material for general characterization or comparison to a known material of interest.

Steve is an expert in microanalysis of asbestos, carbon black, and fly ash while focusing on the analysis and characterization of both airborne and settled dust and debris.
