What We Do
Eleos is pioneering CareOps Automation. By consolidating the entire behavioral care workflow — everything from progress notes all the way to session intelligence — clinicians are freed from time-consuming operational burdens. Eleos takes care of CareOps, honing in on automating operational necessities, including all documentation, compliance administration as well as providing deep clinical insights through session intelligence. Eleos makes evidence-based behavioral care a reality so clinicians, providers and networks can measurably and comparatively track treatment and progress. Now clinicians put all their focus into care itself. So the care they aim to provide becomes the care they actually deliver. Eleos. More Care. Less Ops.
