Geology Expert Witnesses: 6

I bring diverse, combined education, licensing, and credentialing in geology, biology, and hazardous materials management. Indoor air quality as related to asbestos, mold, lead, building hazards, vapor intrusion, OSHA worker and occupant complaints.

I manage a firm of environmental and industrial hygiene professionals while serving as an expert in my diverse field; I have over 70 retained cases complete. I can cost effectively support engagements that may require extensive data gathering across an expanded time frame. I apply my capabilities and credentials across commercial, industrial, and oil & gas settings, with a technical focus on highly regulated industry and real estate.

I have been steadily retained for expert witness services since 1995.

I specialize in structural fire forensic investigation and testing, routinely leverage post-flood emergency response expertise in buildings, specific to microbial disinfection, mold mitigation, and source mold under forensic methods of investigation that may exist under alleged building construction defects. I possess expertise in building systems and mitigating hazards from structures in advance of demolition for asbestos, lead, and other regulated materials.  I prepare, implement (and/or critically review) asbestos specifications, mold remediation protocols, OSHA-driven lead specifications, and remediation soil management plans.

I have evaluated diverse workplaces following loss reports due to alleged safety and public health concerns and offered mitigation strategies for worker safety under OSHA complaints, especially regarding respiratory protection. I have served as an expert for multiple worker injury and wrongful death allegations within the context of environmental exposure.
