This place is located in the San Martin Medical Arts Pavilion building on Arby Ave. When you go in the sliding doors, it's the first door on your left (before the elevators) #190 that says Quest on it. I read the 2 reviews about this place, so I was ready to give them a time limit before I walked out. When I came in, the guy that took my paper work was a bit uptight-ish and not so friendly, but the one that took my blood was very friendly and started small talk about the weekend so that I would relax a bit (not one for getting vials of blood taken :\ ) I wouldn't say I'm a fan, but I do give it 4 stars because I got out of there pretty quickly and my blood guy was nice, even though his front desk buddy wasn't.
