LocalityBiz review

"Their bad billing has us staring down $365 for a single rapid strep test. Literally billed the exact same thing correctly a month later, but they just can't seem to fix the first submission."

LocalityBiz review

"I like Mercy care overall but this location front desk was extremely inconsiderate. My appointment was 2:30 and I arrived at 2:39 to be seen... You’re late. Not a single “how are you today..."
