We are the #1 nonprofit biotechnology organization dedicated to developing effective treatments for ALS.

Our Vision

At TDI, we have one urgently important goal: to end ALS. We envision a future where patients no longer die from ALS and where today's patients are alive, well, and enjoying the company of their children and grandchildren.

Our Values

We are committed to creating and leading a transparent collaborative research process that involves ALS patients today and honors those whose journey with this disease has ended. We are guided by passion, love and the spirit of entrepreneurship upon which we were founded.

Our Research Strategy

In a word: unbiased. We'll take answers anywhere we find them. We're curious, creative, and willing to follow any promising lead. Learn more about our research >
