I just started trying Yoga Tree as the studio is conveniently located around the corner from my work. I have pretty high standards when it comes to a yoga studio and would highly recommend Jason's (the owner) classes. He is the best teacher at the studio by a long shot! Jason's classes are challenging and fast paced with a thoughtful flow that is often missed by some yogis. Each transition to a new posture makes perfect sense and is almost choreographed like a one hour dance. I have had several 'ah ha' moments in this class, not I have not been able to find at other studios. I cannot speak more highly of his Monday 5:15 class if you are looking to advance into those tricky postures.
The room temperature is perfect in the reduced heat classes (not too hot, not too cold, just right!) so that you can get your sweat on with internal heat and an extra boost from the heated room for some added flexibility. The studio is bright and open so I find this studio is good for energizing yoga classes (sleepy yogi's beware). Bonus points for the FREE lockers with combo lock included, free herbal loose leaf tea that changes monthly, and fresh design. Oh yah and its eco friendly! Only downside, no cleaning spray for your matts.
