    Great experience. I made an appointment, got stuck in traffic and showed up late and they still were able to get me in quickly! Jameelah, the phlebotomist, was probably one of the best I’ve ever had in my 36 years! It was seriously quick and painless.

    The tech did an excellent job of blood withdrawal, not bruising at needle site.

    Easy checkin, fairly fast service. My phlebotomist was very friendly and capable. Fast, very good with the needle stick!

    Gayle (PSR) was friendly, right on time (no wait at all!), and I could hardly feel her "stick" to draw my blood. I was in and out in less than 10 minutes! Pre-appointment registration saved lots of time.
