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.

He was a contributing author of the Joint American Society of Safety Engineers (ASSE), AIHA, ABIH, and Board of Certified Safety Professionals (BCSP) position paper outlining minimum qualifications for auditors performing third-party Occupational Health & Safety Management Systems audits. He developed a technical roundtable for the 2006 American Industrial Hygiene Conference and Exposition regarding information technology used to implement environmental health and safety management systems, and is currently a contributing author for the upcoming revision of AIHA’s Industrial Hygiene Auditing, A Manual for Practice.


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

Rob Strode, a Certified Industrial Hygienist (CIH), received his B.S. and M.S. in Microbiology from Colorado State University. He has worked in leadership positions in health and safety, exposure and risk assessment, industrial hygiene, analytical chemistry, laboratory methods development, regulatory compliance, and quality assurance; incorporating the fundamentals of anticipation, recognition, evaluation, prevention, and control of environmental stresses in the workplace and community. His area of practice focuses on expert witness work concerning the workplace environment, with an emphasis on indoor environmental quality (IEQ). Understanding the importance of characterizing hazards and their associated risks, Mr. Strode provides both retrospective and prospective exposure and risk assessment analyses for chemical, physical, and biological agents. He provides effective and efficient solutions to assess and protect workers and their environment by using state-of-the-art field and laboratory methods in conjunction with statistically-based mathematical modeling tools.

Mr. Strode is an active participant in American Industrial Hygiene Association (AIHA) activities on the national and local section levels. He is currently a member of the national AIHA Biosafety and Environmental Microbiology committee and has served in various capacities in the AIHA Rocky Mountain Section (RMS), including the Legislative/Governmental Affairs, Technical Conference, and Education Committees; is a past Education Committee Chair; and is currently President. He co-teaches the annual AIHA-RMS CIH review class, sharing his expertise in chemistry, air sampling, and IEQ. Mr. Strode has coordinated and/or moderated numerous professional development courses (PDCs) including two microbiological-related PDCs developed and presented by the AIHA-RMS Education Committee. He has authored and/or provided publications and presentations in the fields of chemistry, industrial hygiene, exposure assessment, and microbiology.
