    I had scheduled an appointment online, did the check in in the parking lot. Then went upstairs, they called my name within 10 minutes of my scheduled appointment time. I was in and out . The whole thing took about 15 minutes. The ladies are always fantastic.

    I do enjoy going here. They are very quick and professional. Place is clean but can be busy ... suggest getting appointments prior to visiting.

    Gentleman who drew my blood is very skilled, no pain, no unnecessary bleeding. Came with appointment, blood drawn on time.

    The ease of making an appt on the app, checking in and service was less than 30min. After reading some of the reviews...I went at 9am. Just a suggestion...
