What areas do you serve?
QualifiedStudies serves patients across the entire United States. Our routing engine is exclusively ZIP-driven and supports nationwide matching — if a research site in our network has an open protocol within a reasonable distance of your ZIP code, you'll be matched. Our network is densest in major metropolitan areas (New York, Los Angeles, Chicago, Miami, Dallas, Atlanta, Boston, Seattle, Phoenix, etc.) where many academic medical centers and dedicated research sites operate, but we also route to suburban and mid-sized metro sites across all 50 states. For some studies — especially in rare disease, oncology, and gene therapy trials — sponsors will cover travel and lodging so participants can reach a specialized site even if it's a flight away. The fastest way to see what's available near you is to enter your ZIP on QualifiedStudies; the screener will show your matches in seconds.
