HealingMaps Take: This is one of the most unusual ketamine practices in the state, and that’s a good thing. Dr. Elena Christofides brings an endocrinology background, which means she approaches mental health through the lens of hormonal and metabolic function—an angle most psychiatry-led clinics miss entirely. The MediZen Institute arm administers IV ketamine infusions and ketamine-assisted therapy, while Endocrinology Associates handles the broader medical picture. What truly sets this practice apart is insurance acceptance: Aetna-Trinity, MediGold (Medicare), and Tricare are all accepted, a rarity in the IV ketamine world where cash-pay is the norm. For veterans and Medicare patients in Columbus, this may be the only realistic option.
Market Position: Endocrinology Associates / MediZen Institute offers the full ketamine-assisted psychotherapy (KAP) protocol alongside medical-only ketamine dosing — one of the more integrated treatment menus in the metro.

Patient Questions about Endocrinology Associates / MediZen Institute
This 5-question summary is matched to the protocols and conditions Endocrinology Associates / MediZen Institute treats. Editorial responses are HealingMaps-authored, grounded in our 2026 Ketamine Clinic Intelligence Report.
What ketamine protocols does Endocrinology Associates / MediZen Institute offer?
Endocrinology Associates / MediZen Institute offers IV ketamine and KAP — a 2-protocol practice. Patients can switch between or combine modalities without changing providers. Confirm specific dosing schedules and which protocols are recommended for your condition during your consult.
Does Endocrinology Associates / MediZen Institute offer ketamine-assisted psychotherapy (KAP)?
Yes — Endocrinology Associates / MediZen Institute offers KAP, which combines ketamine dosing with structured psychotherapy during the dissociative window. KAP sessions are longer than standalone infusions and priced accordingly. A reasonable consult question: whether KAP is delivered by a single integrated provider, or by a separate therapist working with the prescribing clinician.
Is Endocrinology Associates / MediZen Institute suited for treatment-resistant depression?
Endocrinology Associates / MediZen Institute treats depression via IV ketamine (off-label, evidence-based), and KAP for trauma-anchored depression. 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 Endocrinology Associates / MediZen Institute treat chronic pain conditions?
Yes — Endocrinology Associates / MediZen Institute treats chronic pain. They use IV ketamine for pain, which typically means longer infusion times and higher cumulative doses than mental-health protocols. Common indications include complex regional pain syndrome (CRPS), fibromyalgia, and certain neuropathic pain syndromes. Pain pricing varies significantly by structure: per-infusion vs. multi-day inpatient packages — verify how this clinic structures their billing.
Can Endocrinology Associates / MediZen Institute help with anxiety disorders?
Yes — Endocrinology Associates / MediZen Institute 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.
