HealingMaps Take: One Behavioral gives South County what the Spravato map otherwise leaves to central and west county: REMS-certified esketamine inside an established behavioral-health system rather than a standalone clinic. The practice — Serenity Health, LLC until its rebrand — pairs Spravato with TMS, psychiatry, therapy, and IOP-level care, so patients with more complex needs stay inside one organization. The Cedar Plaza office anchors South County with a second location on Old Ballas Road in West County.
Market Position: One Behavioral occupies the full-continuum behavioral-health slot in the South County market — Spravato plus TMS within a practice that also runs therapy and intensive outpatient programs, differentiated by two decades of metro history and two county locations.
Is One Behavioral Right for You?
✓ Choose One Behavioral if:
- You want insurance-billed Spravato inside a full psychiatric practice
- You may need more than medication — therapy and IOP run in the same organization
- You’re in South County, Oakville, Mehlville, Concord, or Fenton
- The West County office (11709 Old Ballas Rd, Suite 105) is more convenient — same practice
- You value a program with 20+ years of St. Louis history behind it
✗ Look elsewhere if:
- You want IV or IM ketamine — One Behavioral’s ketamine-class option is Spravato
- You’re seeking ketamine-assisted psychotherapy
- You’re searching under their former name Serenity Health — same practice, new name
