I found her website through a google search of "ballet strength training" and was thrilled!  Although I live on the opposite coast from where she is located, she has been very helpful through e-mail. Not only is she encouraging, but she's given me many suggestions. Her videos have given me ideas and her blogs are extremely informative. Even if you live far, you can benefit from Nikol’s personal training expertise!”
