San Andreas, CA…In honor of the nationally recognized “National Night Out” that happens each year on August 1, Mark Twain Medical Center is taking proactive steps to recognize Calaveras County’s first responders. They sent an invitation to local emergency personal to invite them to join them for a free breakfast or lunch at Mark Twain Medical Center tomorrow (8/1). We rely on our strong, trusting collaboration with first responders and would like to use National Night Out as an opportunity to thank them for their tireless efforts serving our community.
