Portrait of an Oakcrest Teacher

An Oakcrest teacher strives to fully understand the transcendental value of shaping the minds and the hearts of our girls during their formative adolescent years. Everything she does is inspired by the belief that her vocation is to help every girl grow in intellect, character, faith, and leadership potential. This belief informs both the content and skills she teaches as well as the behavior that she models. Just as an Oakcrest liberal arts education teaches and hones the ability to think ethically, logically, rationally and imaginatively, an Oakcrest teacher is a life-long learner not just of what, but also of how she teaches. Therefore, an Oakcrest teacher fosters a school culture of self-reflection and mentoring that edifies women as trustees of humanity, leaders who understand that growing in knowledge and virtue is the persevering and loving work of a lifetime.
