- Why Pine Rest
- I chose Pine Rest after completing an away rotation here in my fourth year. I was blown away by how genuinely caring everyone was (and continues to be) – the doctors, nurses, patient technicians, therapists, and janitorial staff. I knew it fit my learning style and would feel well supported as I expanded my knowledge, growing as a psychiatrist and inevitably made mistakes along the journey.
