HealingMaps Take: Tanglewood Collective is a Loveland mental health practice founded in 2025 by Shannon Darling, PMHNP, that combines integrative psychiatric care with therapy. Its ketamine work centers on ketamine-assisted therapy: Tanglewood’s nurse practitioners handle the medical evaluation and ketamine prescribing, and the process includes preparation sessions, the ketamine session and integration afterward. Its site says that, at this time, it connects clients interested in ketamine-assisted therapy with a therapist who offers the therapy sessions, so ask who will guide yours and where. Tanglewood says it accepts most major commercial insurance plus Medicaid and Medicare. It doesn’t offer IV ketamine or Spravato.
Market Position: Tanglewood Collective brings ketamine evaluation and prescribing for ketamine-assisted therapy to Loveland and northern Colorado, inside an integrative psychiatry and therapy practice that bills insurance.
