The staff is knowledgeable, courteous, kind, and thorough with explaining about the medication needed for your specific treatment. I appreciated that.

After being a loyal patient for years today the pharmacist gave me all types of attitude and refused to explain anything except providing conflicting information? Telling me I’m over supplied by 40 days but they just filled me a 14 day supply last week. Years - $20,000 in sales maybe? I’m reporting them to the state for mismanagement. Worries about your license giving me a hard time and now they’re getting an inquiry for being rude and telling me they can’t divulge my own information back to me.
