All of this input is very helpful, not a coat and tie situation but polo would be a nice touch. Firm handshake and eye contact has been a must since he was very small so that shouldn't be an issue at all. My son has talked to the coach twice and doesn't think of everything to ask each time. He does know he'll be practicing with them after a campus tour. Him and my husband will be going this time around so hopefully they'll remember all this guidance I pass along.
