Treatment Philosophy

"Most of the people who come to Bishop Health have already worked hard at getting better — several medications, more than one therapist, real effort. Our first job is to take that history seriously: what was actually tried, at what dose, for how long, and what it did. That audit alone changes the plan more often than any new prescription."

"I trained in both general and addiction psychiatry because the two rarely stay in their lanes — depression and substance use braid together, and treating one while ignoring the other fails both. And I practice interventional psychiatry because some depression genuinely doesn't respond to medication. When that's true, saying so early — and having TMS and esketamine in the same building — is what changes outcomes."

"What you can expect from this practice: unhurried appointments, reasoning you can follow, and honesty when something isn't working."
