The effort you make to pronounce people's names correctly reflects your authentic professional brand.
Instead of saying: "I am going to butcher your name" and then proceed to butcher it ... connect with the person: "Hey, could you tell me how to pronounce your name correctly?"
Funny story: my brother's name is Tareq, and we still laugh about the time during our childhood when someone looked at the roster and asked for Nancy and Gareth Miller" to stand up. We had no idea he was referring to us.
A person's name is precious to them; listen and your effort will be heard.
