I took some small, private yoga classes with Nicole and I have to say that I wish I didn't move away from LA so I could take them a few times a week!  She is knowledgeable, attentive, rigorous and relaxing all at the same time.  She pushed me enough so I felt like I had a workout, yet my mind felt clear and calm when I was finished.  She includes just the right amount of spiritual and meditative insight--enough that it is beneficial, but not so much that you lose track of her point...you know when that happens?  Anyway, like I said, if I could I would attend Nicole's classes all of the time.  And if I ever go visit LA again (which I most certainly) I will definitely try to catch one.  Her classes just make me feel better, both physically and mentally.
