Protecting rights

We affirm that every person who is incarcerated, no matter their background, has the right to appropriate medical care. This right is guaranteed by the 8th Amendment of the Constitution. As medical professionals, we see it as our responsibility to protect this right.

Upholding dignity

We believe that people in prisons, jails, and detention centers deserve to be treated with dignity. We center our work, our language, and our actions in upholding the humanity and dignity of the people we serve.

Embracing inclusion

We hold inclusion at the core of our work. We welcome opportunities to serve all incarcerated people, and invite volunteer clinicians of all backgrounds, identities, abilities, and beliefs to join us in our efforts.

What we do

Expert services

We train volunteer clinicians to provide expert witness services in cases involving incarcerated people. This removes the often prohibitive cost barrier to this critical service. MJA is the first national group of medical experts who work to protect the rights of people in jails, prisons, and detention centers.


We advocate for policy changes needed to ensure that incarcerated people receive their right to medical care. We do so in partnership with legal experts and advocacy groups at the local, state, and federal level.


We educate key stakeholders regarding the medical impacts of incarceration to ensure that the medical needs of incarcerated people are met. These groups include attorneys, policy makers, parole boards, correctional staff, incarcerated people, and the general public.

How it works

Attorneys identify client health concerns and reach out to MJA

Medical record review

MJA pairs attorney with a physician expert witness who evaluates the records


Phone interview

Physician conducts a phone interview to clarify any questions with the client

Expert testimony
