It looks terrible, and of course, there's still a bruise.

Service was quick and efficient. With an appointment, I was in and out in less than 30min. Patty was amazing! She was so quick and drew my blood on the first try. I usually bruise and have issues with people finding my veins, but she got it on the first try with zero hassle. Super sweet, charismatic, and efficient! The waiting room could do with some A/C however, it was quite warm.

Pretty quick service, but make sure you have an appointment, or else you will be sitting there all day.
