TRD is typically defined as two or more prior antidepressant trials without sufficient response — patients meeting that bar are best candidates here.

Does Humboldt Center for New Growth treat chronic pain conditions?

Yes — Humboldt Center for New Growth treats chronic pain. They use IV ketamine for pain, which typically means longer infusion times and higher cumulative doses than mental-health protocols.

Pain pricing varies significantly by structure: per-infusion vs. multi-day inpatient packages — verify how this clinic structures their billing.

Does Humboldt Center for New Growth treat PTSD?

Yes — Humboldt Center for New Growth treats PTSD. Both Spravato and IV ketamine can be used for trauma.

Can Humboldt Center for New Growth help with anxiety disorders?

Yes — Humboldt Center for New Growth treats anxiety, including generalized anxiety, social anxiety, and panic disorder.
