At One Yoga (www.atoneyoga.com) is the best place to do yoga in Scottsdale, plain and simple.  While their prices are somewhat high ($20 to go once, $200/month), considering that you can find many of the same teachers at local gyms (Gainey, etc), you cannot deny that it’s a great yoga experience.  At One has two locations - one in Scottsdale at Shea & Scottsdale, and one in Phoenix at Lincoln and 38th.  The rooms offer a feeling of feng shui, with hardwood floors, high ceilings, and fewer mirrors than most yoga studios.  The classes are typically heated, but not to the point of being unbearable.  The teachers are simply some of the best teachers in the entire country, and Alex Austin teaches the best yoga class I have ever experienced.  The greatest thing about At One Yoga: the students.  While the classes are certainly friendly to beginers, if you visit At One you will be surrounded by experts who will amaze you with the skill and beauty of their practice.  The girls who work at the front desk are often rude, but if you ignore them they will ignore you. At One offers a great culture of yoga.  Every time I leave, I’m glad I went.  And I don’t know of anyplace else in Scottsdale where I can say the same thing.
