Last month, Envista saw its largest onboarding group of 2023, welcoming nine new experts across the US, one expert in Canada, and one expert in Australia. We are joined by three fire and explosion investigators, five civil/structural engineers, one electrical engineer, one mechanical engineer expert, and a building consultant.
