Placeholder B

In 2004, MASH (formerly MedFirst) was founded by a group of emergency room physicians and healthcare executives who recognized an unmet need in the Buffalo Niagara region for non-emergency services, where patients could receive the highest standard of care at a reasonable cost when their own doctor’s office was closed, and without having to wait for hours in an emergency room. 

In August 2012, MedFirst Urgent Care officially changed its name to MASH Urgent Care.
