Public Health Microbiologist Training

ASK our trainees

"Having worked as a CLS in microbiology for the past five years at a clinical lab, I’m going through the Public Health Microbiologist training to become a well-rounded microbiologist. I have enjoyed the training tremendously, especially for subjects that my previous CLS training didn’t cover much in depth."
