Jessica Greenwalt is the Co-Founder of CrowdMed, a companythat solves the world's most difficult medical cases faster than ever before using the 'wisdom of crowds'. We help patients whose doctors tell them there is no hope—or that their symptoms are in their heads. Some of the patients who come to the site have been suffering without a diagnosis for years and have gotten the correct answer for their case from our medical community in a matter of weeks.
