Medical Advocates for Healthy Air


Medical Advocates for Healthy Air (MAHA) is a statewide network of medical and health professionals leading the call for cleaner air and climate health.

They also receive advocacy training enabling them to advocate for strong, clean air policies.

“These kids can’t breathe. Their cases can be so severe that they require acute care and end up being air-lifted to critical care facilities.”

Candace Cahoon

Respiratory Therapist at Vidant Roanoke-Chowan Hospital, MAHA Advisory Board Member

Education and Advocacy


MAHA conducts educational trainings across the state to inform health professionals about the health impacts of air pollution and climate change. The trainings also discuss how health professionals can make a larger impact in their community through advocacy. MAHA conducts ad hoc trainings (e.g. grand rounds, in-services, student classes, etc) as well as regular monthly trainings with Duke Health and Atrium Health’s Pediatric residents. If you are interested in bringing this training to your community, please email [email protected]

Nurses, physicians and pharmacists are 3 of the top 5 most trusted professionals. This gives health professionals a strong and credible voice to help improve the health of their community. MAHA does this by leading and participating in advocacy activities across North Carolina. From submitting public comments to attending public hearings to writing letters to the editor to speaking at press conferences to talking with policy makers to joining boards and commissions, we ensure the health voice is heard. Below are a few recent advocacy actions MAHA has taken.

MAHA Advisory Board


Consisting of medical and health professionals from across the state, the Advisory Board participates in a quarterly one-hour conference call to discuss current issues and directions for MAHA’s advocacy and education initiatives. We are seeking to diversify our membership with representation from minority health professionals and rural communities. If you or someone you know would like to serve on our Advisory Board, please contact us.

Charged with the responsibility to prevent disease whenever they can, medical and health professionals have an important role to play in protecting their patients from air pollution. Trusted sources of information who see the impact of air pollution and climate change on the health of their patients, the nurses, physicians, respiratory therapists, public health educators and other professionals participating in MAHA can make an impact with a unified voice.

MAHA works closely with partners such as medical schools, healthcare organizations, research institutes, government agencies and other environmental and health advocates in order to ensure we are engaging with our members and our policy makers as effectively as possible. Committed healthcare leaders representing diverse professions who serve on MAHA’s Advisory Board help with outreach and engagement strategy. If you are interested in having MAHA partner with your organization, please contact us!

As a MAHA member, you will have access to healthy air trainings, information on research and tools that can help patient care, and convenient opportunities for communicating with policymakers.

It does not have to take much time to be an effective advocate because MAHA helps you fit advocacy into your schedule. Advocacy opportunities range from simply adding one’s name to a sign-on letter, to meeting with a legislator or testifying at a policy making hearing. You can choose the opportunities that are right for you.

Our email communications include a monthly newsletter, invitations to events such as the NC BREATHE Conference, trainings or local meetings, and action alerts when we need your help to promote a clean air policy — or to prevent a policy that will harm our air quality.
