Inserting Player Name into Text?

This seems very basic, but I've been trying to learn lua better by doing this on my own.

function oc(pl, dc) 
	if (dc.Name == "Yes") then 
		print("You own this tycoon!") 
		workspace.Tycoon.DoorHeader.UnownedPharmacy.Name ="'s Tycoon" 
	end 
	if (dc.Name =="No") then 
		print("You do not own this tycoon!")
	end 
end 
script.Parent.DialogChoiceSelected:connect(oc)

more specifically, this line;

workspace.Tycoon.DoorHeader.UnownedPharmacy.Name ="'s Tycoon"

After Name= , I ideally want it to chance the name to Carcanken's Tycoon for example, if I executed the dialog.

Thanks!
