I can't comment on this, exactly, more than to say it certainly can't HURT to have a relevant alum write your LOR.
What is more striking here is the conflict of interest in having your father write your LOR. Obviously there's a bias there, and, even if he reveals himself in the letter, my understanding is that such a recommendation would be discarded by the admissions committee. Any chance you're friendly with or have shadowed any of his ATSU alumni buddies?
