Message from the Founder:


Diseases such as cancer affect nearly every one of us, at times striking with often devastating consequences at the heart of a nuclear family nest, in our close family circles, in the local community, the nation and the community of nations.  


Whether it is through the most recent Zika and Ebola virus epidemic outbreaks, or the now uncomfortably familiar HIV epidemic, or a crippling autoimmune disease such as rheumatoid arthritis, we all are reminded how vulnerable we can be and how connected we are as human beings. We are confronted with the necessity to unite and stand together in the fight against these dreadful diseases.


Our multidisciplinary teams of employees and partners have chosen to dedicate their careers, talents and expertise to this cause. I am personally grateful and thankful to them, speaking not just for myself but also with the firm belief that I do so on behalf of patients and their families. I chose the company name “L.E.A.F. Pharmaceuticals” to reflect our core belief, our commitment and our dedication to the value proposition of Lifting and Empowering All Families (L.E.A.F.) through the development of innovative, effective and safe medicines for patients. Together, I believe, we can and will make a difference.


Best wishes,
