The office at 1640 Newport Blvd was great. My first time there. Had scheduled an appointment; only waited 2-3 minutes once arrived; technician friendly, polite and knows how to draw blood :)

I was called into the room right away and the phlebotomist was friendly and professional. I was in and out in no time and the blood draw was painless!
