I originally scheduled a appointment but end up missing it. So I decided to just do a walk in ofcourse I called and spoke to the lady first because my last experience with sonoraquest at the banner hospital location on dobson and southern went horrible! For this location the lady told me they allow walk ins prior to driving down here. Shure enough I show up got my blood drawn within 5 minutes. The ladies working there was polite and professional. They seemed quite happy making jokes that provided a positive atmosphere. Would I go back of course! But take my advice about the southern and dobson location stay far...far...far...away...as you can from there they had me waiting 2 hours before drawing my blood for the wrong doctor and taking the wrong blood orders and then expected to charge my insurance for theur mistake which is BS. SMH but this location is so far the best I've ben to out of all my sonoraquest visits.
