Who is Alex's Dad from Like Jake and Me and what is their importance?

Alex's dad is an entomologist. He studies spiders. Because of this, Alex knows a great deal about spiders. Alex's dad is also sensitive to his sons needs. In Order to encourage Alex's softer side, he signs him up for ballet lessons. Knowing Jack wouldn't understand, he keeps it a secret from him..... at least until he sees Jake dancing on the front porch of his house.
