About OneFifteen

We Are On A Journey To Reverse The Course Of Addiction In Our Communities

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

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

Our Mission

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


The best care starts with the best information. Despite great efforts in research and medicine, we haven’t yet learned which treatment options work best, and for whom, due to a lack of high-quality information. As a learning health system, we aim to change that.

With patient consent, OneFifteen applies analytics to measure the effectiveness of various treatment choices throughout the full continuum of care, while maintaining stringent standards for patient privacy and data security. We use current standards for evidence-based care and continuously evolve our approaches based on the insights we derive from our learning network.

We plan to share knowledge both within OneFifteen and more broadly to improve care and advance the field of addiction medicine.


In order to advance the field of addiction medicine, OneFifteen embraces learning and discovery. The OneFifteen model considers the whole person and their needs, rooted in scientifically backed medical care.

We promote Medication Assisted Treatment (MAT) 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.


A healthy life free of addiction requires more than medical treatment一people need longer-term support services to build resilience and rebuild connections in their community. 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.

Our History

Opioid addiction is the health epidemic of our generation, and it claimed more than 115 lives from unintended overdoses each day in 2016. Driven by a desire to reduce opioid-related deaths, Verily (an Alphabet company) started to explore the gaps between today’s treatment models and better outcomes. The Verily team began discussions with Alexandria Real Estate Equities (ARE) to conceive of an optimal environment that could address the many unmet needs of people in recovery.

Meanwhile, in Montgomery County, Ohio, healthcare providers and public services were at the front lines of what many have termed “ground zero” for the opioid epidemic, and began taking action through public alliances to stem the tide of overdose in their communities. 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.

Two health networks, Kettering Health Network and Premier Health, joined Verily to create OneFifteen, a not-for-profit ecosystem in Dayton, to provide clinical care and rehabilitation, and wraparound services such as vocational training to people in recovery. Together, Kettering Health and Premier have more than 180 years of experience serving the Miami Valley and local communities. Now, with Verily, ARE, Kettering Health, and Premier, the OneFifteen team is working with local experts and community leaders to create a long-term solution that arms families and their loved ones suffering with addiction with the tools and the hope that recovery is possible.
