Agency Representatives in 2024 and 2025
The individuals listed on this page served as representatives from ICCVAM member agencies in 2024 and 2025. ICCVAM includes three types of representatives:
- The Principal Agency Representative is the primary source of communication from his or her agency to the committee and NICEATM. He or she regularly attends all ICCVAM meetings and teleconferences, coordinates participation of other representatives from the agency, and casts the agency’s vote on occasions when formal voting is required.
- Alternate Agency Representatives participate in ICCVAM committee activities in place of the principal when necessary.
- An agency may designate one or more Other Agency Representatives to participate in ICCVAM to provide broader representation or expertise.
