Dr. Engstrand talks about “Give Back Sunday,” a program sponsored by Zwanger-Pesiri, that offers free medical testing to the under-insured, uninsured and unemployed in Nassau and Suffolk counties on Long Island, NY. She suggests that more companies and more people could and should follow this example by volunteering their time and services to those who are unable to afford it, or whose health insurance often delays or will not cover life-saving tests and procedures.
