HaRT³S is an award-winning Washington State-based social purpose corporation (chapter RCW 23B).

The Harm Reduction Treatment, Training and Technical Solutions (HaRT3S) social purpose corporation was created to provide information and training systems to substance-use treatment and other service providers using evidence-based and culturally-appropriate means of reducing substance-related harm and improve quality of life for their clients and their communities.

HaRT³S Seeks To:


Honor Family & Community

Honor the importance of family and community involvement in substance-use treatment and recovery approaches.

Amplify Community Voice

Center and amplify the voices of community members who have been marginalized by their substance use, its sequelae and other systemic inequities.

Strive for social justice

Strive for social justice and racial equity for people who use substances, their families and their communities.

The mission of this social purpose corporation is not necessarily compatible with and may be contrary to maximizing profits and earnings for shareholders, or maximizing shareholder value in any sale, merger, acquisition, or other similar actions of the corporation.

We are committed to donating 20% of profits to community-led harm reduction organizations.

What Our Partners are Saying

Having worked with Drs. Clifasefi and Collins for the past decade, primarily in their research and evaluation efforts, I can attest to both their professional competence and deep dedication to innovation in the delivery of harm reduction services to individuals struggling with their use of substances. They are creative and tireless in efforts in exploring the various methods by which harm reduction interventions can be implemented in a community. They consistently demonstrate the value of collaboration in their work with organizations and individuals.

Drs. Collins and Clifasefi have been invaluable partners to DESC. Their expertise in the field of harm reduction is rivaled only by their ability to center the voice of those with lived experience. DESC is a better organization, and our clients live healthier lives, due to their work.

Noah FayHousing Director, Downtown Emergency Service Center

Drs. Clifasefi and Collins have always provided a tremendous community asset in their desire to provide equitable services for people who are using drugs. The research and training they have provided the community has advanced the understanding, decreased stigma and has helped evolve services to individuals who are in need of the help, in a way in which they are willing to receive it. I have learned a tremendous amount from Seema, Susan and colleagues and look forward to the ongoing collaboration.

Some people practice harm reduction. Some people advocate for harm reduction practices and policies. And some people do evaluation and research. Very rarely do you find people who are capable of, and committed to, doing all of those things. Drs. Seema Clifasefi and Susan Collins are the truly rare people who are skilled at all of these and bridging the divides between advocacy, evaluation, and practice practice.

Kris Nyropformer Director of Harm Reduction Practices at the Public Defender Association and former LEAD National Support Director

We are deeply grateful for the collaboration we have had to date with Drs. Seema Clifasefi and Susan Collins. They have consistently shown their ability to engage with community integrated programs in an appropriate, thoughtful, and low barrier manner.
