Allison Rivers Samson


Allison is a certified Nia Black Belt instructor and has been practicing Nia enthusiastically since 2008. “I started dancing formally at age 5 and stopped at 15, when my mom and I moved across the country, and away from my dance studio. Many years later when I became a mama, it was clear that I needed to return to dancing for a more expressive physical outlet. Before Nia, exercising and sweating felt like something I had to do, rather than something I wanted to do. But now I get a fabulous physical workout and an an opportunity to play, while exploring my emotional, spiritual, and creative realms with joy, ease, and fun. In the dance, I am reminded of who I am, and my entire being is reawakened, which not only benefits me, but also means I have more “me” to give to my family. In addition to teaching Nia, Allison shares her passion for health and wellness as a vegan chef, business owner, and certified health coach.
