The Artemis Association was founded in 1994 in Athens, Greece. Its name is a tribute to a young girl afflicted with Histiocytosis who passed away when she was only 18 months old. In 2019 we created Friends of the Artemis Association so that we could have a dedicated space for our community members in the U.S. 

Over the past 30 years the scope and impact of our work has grown tremendously. We are an active contributor to scientific research and fundraising, and our association has been financing not only the Nikolas Symposium – an annual international scientific think tank – but also numerous research programs around the world which focus on Histiocytic Disorders. In collaboration with our Greek affiliate Histiocytosis Hellas, we also work to inform public opinion and increase the amount of funding available for researchers.

Across all locations, our core mission remains the same: to provide the public – patients, friends, family members, and medical practitioners – with advice and support around this rare set of diseases.

About Us

“When my son Nikolas was first diagnosed with Histiocytosis, I felt alone and afraid of this extremely uncommon disease. Back then data was scarce and unavailable to the public. However, as any parent who has faced a child’s illness will testify, access to information and a support system is crucial. Knowing that you are not alone and understanding what you are facing prepares you to better handle whatever comes your way. Hence, I decided to create an organization dedicated to providing both encouragement and information to other parents.”
