I have had health problems for many years. After two knee replacements over the past two years, I was encouraged by a friend to try Dahn Yoga at the Rancho Cucamonga Body and Brain Center. I loved it immediately! I have only been going for about two months, but my mobility and flexibility have increased immeasurably. Stress had also been a problem for me, but now I find that I am much more peaceful in my everyday life. Even my family has noticed the difference! For my birthday, my sister gave me a three month membership gift certificate. It was the best gift ever. I love the Body and Brain center and Ana Maria, the main instructor!
