Jon HeintzJon A. Heintz
Executive Director

Jon joined ATC in 2005, and is responsible for project management, oversight, and quality control on the development of ATC products and publications.

Prior to joining ATC, Jon served as a structural design and consulting engineer in professional practice. A licensed civil/structural engineer in California and Alaska, he has more than 25 years of experience in advanced seismic analysis, evaluation, design, and retrofit of buildings, and collaboration with university researchers in analytical investigations.  He has managed more than 50 major ATC projects involving earthquake, wind, coastal inundation, and man-made hazard mitigation issues, including performance-based design, soil-structure interaction, and general structural design issues covering the spectrum between commercial and residential building construction. He is actively involved in the development of guidelines, codes, and standards for existing buildings, and has participated in post-disaster damage investigations following the 1989 Loma Prieta, 1994 Northridge, 1999 Chi-Chi, and 2010 Chile Earthquakes, and Hurricanes Katrina and Rita in 2005.

Michael Valley
Director of Projects

Mike joined ATC in 2023 and is responsible for project management, oversight, and quality control on the development of ATC products and publications.

Prior to joining ATC, Mike spent 32 years as a consulting engineer in private practice. His practice included a balanced mix of new design; evaluation and rehabilitation of existing construction; and applied R&D, code development, and education.  He has developed special expertise in seismic design, foundation analysis and design, and development of codes and standards.  In recent years Mike has been a key participant in the development of performance-based seismic design approaches, and he has applied those approaches to both new and existing construction, especially for highrise buildings and where enhanced seismic performance is desired (as for hospitals and other essential facilities). Mike also has extensive experience as an ATC consultant serving as a reviewer, a technical contributor, and Project Director on multiple ATC projects.

He is retired from federal service as a Senior Geophysicist with the Federal Emergency Management Agency (FEMA), Mike comes to ATC with more than 30 years of experience in hazard mitigation program management and policy development, post-disaster response and recovery, and problem-focused research and development in support of FEMA’s efforts under the National Earthquake Hazards Reduction Program (NEHRP). He has led FEMA’s earthquake-related work with the International Code Council and has been involved with the development of national model codes and standards since 1984.

In his career at FEMA, Mike has led the development of countless major FEMA publications, including: FEMA 350 Recommended Seismic Design Criteria for New Steel Moment-Frame Buildings and its series of companion reports (ATC-41 Project series), FEMA P-58 Seismic Performance Assessment of Buildings, Methodology and Implementation (ATC-58 Project series), FEMA P-695 Quantification of Building Seismic Performance Factors (ATC-63 Project), FEMA P-2018 Seismic Evaluation of Older Concrete Buildings for Collapse Potential (ATC-78 Project), and FEMA P-2090/NIST SP-1254 Recommended Options for Improving the Built Environment for Post-Earthquake Reoccupancy and Functional Recovery Time (ATC-137 Project). With Mike’s extensive knowledge of federal government programs, and past collaboration with state and local agencies, hazard mitigation partners, and code development organizations, we look forward to how his unique experiences will help serve ATC’s client needs and objectives in the future.
