Treatment Philosophy

Adam and Logan's treatment approach is rooted in the understanding that first, we are made in the image of God, second, that our biology, psychology, and spiritual state have been impacted by the Fall, and third, that the redemptive work of Jesus Christ on our psychology begins with salvation and continues through the faithful stewardship of our mind and body. We hold strongly that medication does not constitute a lack of faith in God’s ability to bring miraculous healing but that it may be prayerfully considered when appropriate and accepted with thanks as a gift from God.
