Our President and founder

This is the story of a passion: My late father, Mirko Beljanski, PhD, a biologist and biochemist, worked for over 30 years at the Pasteur Institute in Paris, France studying DNA replication and transcription.

It was his fundamental research that brought to light the fact that, when exposed to certain pollutants, the normal structure of DNA is altered and destabilized, and that this progressive and cumulative process can compromise the immune system. In doing so, Mirko Beljanski became the father of modern environmental medicine

Despite a growing “Green” movement, we are polluting our environment more and more every day. It is time to take an environmental approach to health by looking at our surroundings and getting rid of the toxins that are making us sick, not just by taking another pill to numb the symptoms.

Traveling extensively around the world, I have the privilege of speaking to many audiences as well as health practitioners about the importance of environmental medicine, detoxification, and natural health approach.

Maison Beljanski, a townhouse in Midtown Manhattan will welcome you with a restorative cup of OnkoTea®. Don't miss this opportunity to inquire about our dietary supplements and natural skincare products, free of toxicity, based on the Beljanski® Approach to Wellness, a holistic way of life to AVOID environmental toxins, RESTORE balance and ACHIEVE cellular homeostasis when needed.

Thank you,

Sylvie Beljanski
