For over 130 years, health care professionals have been called upon as patriots caring for our nation’s wounded military. First purposed by President John Adams to provide “relief and maintenance of sick or disabled seamen,” what is now the U.S. Public Health Service (PHS) has taken on far expanded roles and responsibilities in our society. For example, following Hurricanes Andrew and Katrina, PHS health care professionals established field hospitals and pharmacies, supported local health care efforts, and provided access to clean water, vital vaccines, and much more.
