Mr. Slosky provided leadership and expertise in low-level radioactive waste management on a committee of the National Academy of Sciences. In recognition of his policy contributions, the U.S. Secretary of Energy appointed Mr. Slosky to the Waste Isolation Pilot Plant Blue Ribbon Panel. He was the co-chair of the Denver Metro Chamber of Commerce’s Environment Committee.

Currently, Mr. Slosky offers his expertise in the transformation and redevelopment of contaminated properties to risk-adverse financial institutions, real estate developers, and law firms.


Richard P. Lesser, M.S., C.H.M.M.

Richard Lesser, M.S., MBA, is a Certified Hazardous Materials Manager and senior project manager with 25 years of environmental experience. He is very experienced with the regulatory and technical foundations of the environmental industry, successfully completing projects governed by many environmental statutes including RCRA, TSCA, CERCLA, CWA, CAA, NEPA, BRAC, and AEA. He has been effective in leading highly technical negotiations with environmental regulatory authorities, on topics ranging from detonation permits for destruction of highly hazardous explosive wastes to disposal requirements for newly regulated, low-hazard wastes. Mr. Lesser has extensive multidisciplinary experience with modern principles in environmental and analytical chemistry, regulatory applications, and quality assurance resulting in cost savings and efficient environmental assessments, with several of his project successes documented in his twenty-two publications and public presentations. He has hands-on, design, and interpretive experience in sampling; evaluation of environmental matrices and high concentration waste materials; and use of analytical measurements to assess regulatory implications. He has been successful with mentoring subsidiaries, affiliates, and managers in the art of environmental management.

For ten years, Mr. Lesser has worked to resolve conflicting local development and managed growth issues. Two of his most recent efforts involved the facilitation of a development proposal that had engendered local opposition, and reconciling conflicting industrial/residential land use authorizations within his local community.

Mr. Rasmuson has over twenty years of progressive industrial hygiene experience. He has conducted numerous exposure evaluations for physical, chemical, and biological hazards and has developed appropriate risk management solutions. His research interests have included stochastic methodologies to define exposure assessment and risk assessment uncertainties and biostatistical methods to evaluate precision and accuracy of the exposure reconstruction process. He has taught exposure reconstruction methodologies at national American Industrial Hygiene Association meetings and professional development courses. Mr. Rasmuson also holds a Master of Science in information systems and develops and audits occupational and environmental health and safety (OEHS) management systems. He has consulted on industrial hygiene and OEHS management system issues for government research facilities; geological, pharmaceutical, and dental laboratories; waste water treatment plants; oil and gas production facilities; manufacturing and mining operations, and renewable energy sites.

Robert D. Strode, M.S., C.I.H.

Mr. Strode is a Certified Industrial Hygienist (CIH) with over 25 years of laboratory, field, and management experience and is the Technical Director of Industrial Hygiene Services at Chemistry & Industrial Hygiene, Inc.

His areas of expertise include classical industrial hygiene, indoor environmental quality (IEQ), field and laboratory methods and analyses, and support for commercial building and multi-family housing management programs dealing with environmental agents such as mold, radon, asbestos and lead. Mr. Strode has conducted hundreds of air quality investigations related to occupational and environmental exposures and routinely performs exposure and risk assessments for chemical, physical, and biological hazards. He earned his Master of Science in microbiology, providing particular expertise in the fungal/bacterial aspects of his IEQ work. He is a member of the national American Industrial Hygiene Association (AIHA) Biosafety and Environmental Microbiology committee and is Past-President of the AIHA Rocky Mountain Section. He has developed quality assurance programs, operations and maintenance programs, health and safety plans, and remediation and abatement design documents and project specifications. Mr. Strode has provided training in various subjects including OSHA and EPA training in hazardous waste, exposure and risk assessment, fungi, asbestos and lead, general industrial hygiene principles, and co-teaches an annual CIH review course. He has authored and/or provided publications and presentations in the fields of chemistry, industrial hygiene, exposure assessment, and microbiology. Mr. Strode is a 2009 AIHA Fellow Award winner, nominated by industry peers and awarded to less than five percent of the AIHA membership for contributions to the field of industrial hygiene.
