I had a similar experience that Amanda F. had. The first time I came here it was decent, i would have given this place 5 stars if it were like the first time each time. I had previously gone to the Tempe location and noted that this place seemed much more clean and organized. For your first time, or your return after being absent for a long time like myself, you go through the orientation which can take 3+ hours. After that, and a sort of physical (asking questions and blood test) they then start the actual process. The first time here was odd because they had to stick me twice. They said I needed to drink more water the next time I come in, must have been some dehydration issue. But eventually everything worked it...for this first time.
I came back the following weekend and was one of the first several people there. This time, they stuck me and messed up. They did it completely wrong because when it started returning blood it wasn't going into the right place but forming a "bubble" of blood in my arm! I had to holler out for them to take care of the issue. They then tried sticking me again but "missed", and started to basically try again and again like they were using my arm for practice. It was like they were guessing where my veins were and just poking in hoping to hit something. They quit once they noticed I wasn't liking this and had me lay down with some water and not return for a couple months. I haven't been back and don't ever intend to.
This place has given me a fear of needles that I never had before. Just a couple people know what they're doing. They all seem to be fresh out of school or something. Stay away!
