Patient Questions about Greater Wellness Clinic

This 3-question summary is matched to the protocols and conditions Greater Wellness Clinic treats. Editorial responses are HealingMaps-authored, grounded in our 2026 Ketamine Clinic Intelligence Report.

Is Greater Wellness Clinic suited for treatment-resistant depression?

Greater Wellness Clinic treats depression via IV ketamine (off-label, evidence-based). Insurance coverage is rare for IV/KAP — most patients pay out of pocket. TRD is typically defined as two or more prior antidepressant trials without sufficient response — patients meeting that bar are best candidates here.

Does Greater Wellness Clinic treat PTSD?

Yes — Greater Wellness Clinic treats PTSD. Ketamine for trauma differs from depression treatment: dosing is often lower per session, and pairing the protocol with trauma-focused therapy between sessions is common. A reasonable consult question: whether PTSD patients here typically use ketamine alone or alongside an outside therapist.

Can Greater Wellness Clinic help with anxiety disorders?

Yes — Greater Wellness Clinic treats anxiety, including generalized anxiety, social anxiety, and panic disorder. The evidence base for ketamine in anxiety is less robust than for depression, but it can be a meaningful option for patients who haven’t responded to SSRIs or benzodiazepines. Worth asking which of their protocols they typically recommend for anxiety-primary patients.
