Stillwater

Welcome to Stillwater

A quieter kind of psychiatry, with time to listen and care that fits your life.

Stillwater is a small, independent practice for adults and teens. We keep our schedule unhurried so every visit has room for real conversation, and we bring medication and therapy under one roof so your care feels connected.
