Addressing America’s Drug Epidemic with a Personalized Approach

In 2016, 115 people died each day from opioid overdoses in the United States—that number continues to rise. We are on a quest to reverse this course.

Our vision is to lead a movement that gives people hope for today and offers communities a better tomorrow.

Our mission is to heal people experiencing substance use disorders through learning, science, and partnership.


We partner with community-based organizations, state and national stakeholders, and, most importantly, our patients to offer unique, holistic addiction treatment that puts people and their communities first.

Recovery is not a 28-day process. At OneFifteen, we open our arms to like-minded organizations ready to join us on the journey to support people as they realize a life free of addiction.


OneFifteen uses current best practices for evidence-based care. Providers and clinicians continuously evolve their approaches based on the learnings from patient reported, clinical, and claims data.

OneFifteen actively shares learnings to improve care and advance the field of addiction medicine.


We promote Medication for Opioid Use Disorder (MOUD) as the gold standard of care for many substance use disorders. We also embrace promising practices as options for our patients and rigorously evaluate how well these practices may help people manage their substance use disorders.

We are excited about contributing to next-generation approaches and participating in research to discover the treatments of tomorrow.

Our History

OneFifteen’s name honors the 115 lives lost from unintended overdoses each day in 2016.

OneFifteen is a non-profit organization founded in 2019 by five organizations, who came together with a shared goal to provide solutions for people living with addiction.

  • Verily, an Alphabet company, whose mission is to bring the promise of precision health to everyone, every day.
  • Alexandria Real Estate Equities
  • Premier Health
  • Kettering Health Network

OneFifteen opened its campus in Dayton, Ohio, serving residents of Montgomery County. In Dayton, the knowledge, need, and drive of the public and private sectors to solve this crisis were a natural fit with an innovative vision. In 2024, OneFifteen will begin expanding services.
