Meet the Officers


The California Theta Chapter officer team is made up of eight Executive Board members and eight Chairpersons. The reasoning behind this specific number of Officers stems from the wisdom of having “too many cooks in the kitchen” and the reasoning why a larger team is not necessarily more efficient than a smaller one.
