Who is introduced first in business etiquette – the man or the woman?
U.S. business etiquette does not recognize the gender of a person; therefore, it does not matter if a woman or a man is introduced first. In a business situation, a person of lower rank should always be first introduced first to a person of superior ranking. For example: “Mr. Smith [CEO], I’d like you to meet our new assistant.”Source:California State University, L.A. Asian Pacific Business Institute: Business Etiquette in the U.S.
