This was the best lab experience I have ever had! I am not a fan of needles but Diane was so sweet, put me right at ease and the actual blood draw was completely painless. I will definitely come back here for any future labs.

There is a really nice woman working here. Very efficient service and scheduling is easy. After my extremely positive experience with Quest - I will be sure to only purchase health insurance that partners with Quest in the future.

Things went swimmingly once I found the quest office, as the technician, Diane, was well qualified, and a great conversationalist. When sharing the address of this venue, I suggest you mentioned specifically that it’s inside the Safeway store so people can find it more easily.
