“You’ve led us so far. I can hardly believe we’ve landed in miracle territory. Everyday gets easier, less painful, less fearful, more joyful, more hopeful. There are not words for my gratitude. We are forever changed. Weathered an unthinkable storm. Got a chance to know God and each other in a way we never could have. Thank you Josh. You’ve been our angel. "

Sarah, 40

We will help you overcome your greatest strongholds and learn to connect more deeply to God, to yourself, and to your partner.
