Global Medical Knowledge Alliance (GMKA) is a 501(c) (3) non-profit organization working to improve cancer and trauma care in Ukraine and globally. Our focus is creating physician and patient educational content that is evidence based, written by experts, and available through an online educational platform. Since Russia’s invasion of Ukraine, we have expanded our work to include medical relief efforts. We work to develop and distribute educational materials in the Ukrainian language, provide medical supplies, and support patients and medical professionals in this time of crisis. For more details about our efforts, please visit the “Our Projects” page.

The GMKA education team creates and distributes educational materials to physicians and patients. Members of our team are:

Diverse group from around the world

Our educational materials respond to the critical need for open access, reliable, and evidence- based information in Ukraine and globally. Our articles are short, practical, and discuss the state-of-the-art practice. GMKA articles undergo rigorous peer review and are translated into Ukrainian by trained medical translators. Additional languages will be added as the GMKA network grows.

Every dollar donated to GMKA is tax deductible. Funds are used to provide critically needed surgical supplies, assist cancer patients in obtaining care disrupted by war, and creation and translation of our evidence- based educational materials, among other crucial efforts.

We utilize personal connections and well- established networks within Ukraine to provide humanitarian aid where it is needed most.
