Another option is to see if a clinic in your area is part of Mayo Clinic Care Network. The Mayo Clinic Care Network helps keep care local by providing guidance and answers to many questions that might otherwise require a specialist referral.
These hospitals have full access to Mayo Clinic’s knowledge and expertise. This spares patients the expense and inconvenience of additional appointments and unnecessary travel. https://www.mayoclinic.org/about-mayo-clinic/care-network/network-members
