A pupil is not above his teacher; but everyone, after he has been fully trained, will be like his teacher.
Instructors at Oak Hill are men and women whom you would want your child to be like.  They are skillful in their teaching.  They pursue academic rigor for themselves and their students while seeking to bring God’s word to bear on all subjects.  They show a testimony of love for the Lord, humility in character, and accountability to local churches.
