Boutique & Tea Room in New York City



Located in the heart of Manhattan, Maison Beljanski is the culmination of a long project led by Sylvie Beljanski, daughter of Dr. Mirko Beljanski.

Entirely dedicated to the Beljanski® Approach to Wellness, the boutique will also serve as a tea room. We invite you to visit us at Maison Beljanski where you can enjoy a delicious cup of OnkoTeaTM, participate in health and wellness coaching sessions, or browse quality dietary supplement and skin care lines.

Many informational meetings and conferences are planned for 2018.

We hope you will join us for these educational and fun events!






Why are we called Maison Beljanski anyway?




Maison Beljanski is named after Dr. Mirko Beljanski, "the Father of Environmental Medicine." Mirko Beljanski, PhD (1923-1998), was a French molecular biologist who worked for over 40 years studying DNA replication and transcription. Born in the former Yugoslavia, he worked his way from a small village with no resources to become a researcher at The Pasteur Institute in Paris, France, one of the top research institutions in the world.

At the time of his untimely death in 1998, he left behind a legacy of fearless innovation as well as an impressive body of work including two books, 133 articles published in peer-reviewed scientific journals and numerous patents. Most importantly, his lifelong dream of bringing nature and science together to improve the health and well being of people is now continued through the work of The Beljanski Foundation, Inc.
