Dr. Yung Park guides Elevate Medical’s Certified SPRAVATO® Treatment Center in Midtown Manhattan and Pleasantville, NY. She works with people facing treatment-resistant depression, thoughts of suicide, and feeling emotionally shut down or disconnected.

Her approach is calm, grounded, and human. While she brings years of clinical experience, she starts by simply being present—listening closely, without rushing or trying to fix. She believes real healing begins when people feel safe enough to share what’s true for them, at their own pace.

Instead of steering the conversation toward specific outcomes, Dr. Park creates space for reflection, allowing insights to unfold naturally. She’s more curious than directive, and sees every person not as a problem to solve, but as someone in evolution—finding their way, just as we all are.

When she’s not working, you’ll find her walking in nature, birdwatching, creating poetry—on paper and through gardening—and spending time with her two pups, SaLang and Mandu.
