    The Technician that helped me was polite, thoughtful & kind. It also was very quick, having an appointment & using the App to check in when we arrived. 👍🏼

    The Pittsburg location is much better than the Antioch location. I live 2 minutes away from the Antioch location and the woman at Antioch is condensing and rude. I would rather drive 18 minutes to Pittsburg than go to the rude Antioch location.

    Lab tech was pleasant and professional. No issues whatsoever and I was even able to be accommodated before my appointment time.
