HESA was founded in 2012 by Susan Foley, a productive businesswoman and Nicola Nelson a successful environmental attorney. After their diagnosis of Hashimoto's Encephalopathy they both scoured the internet for information about HE...
and found little to no information.
Soon, they both found an online support group where they happened to find one another and soon decided they wanted to help others with this little known disease. That is when they formed HESA. Susan and Nicola didn't stop there...they also published two of the only books available on HE.
In April of 2019, HESA joined with other autoimmune encephalopathy/encephalitis organizations
and held a symposium in New York City.
We look forward to the next project to raise awareness and advocate for our community,
