Karen Williams

Lead Instructor & Director of Aromatherapy Education

I love to create amazing blends that inspire and promote a healthier lifestyle. I got my start many years ago as a registered nurse working in the hospital system. But along the way I knew something was missing. I wanted to help people more holistically. Then, I discovered essential oils, and my approach to life changed forever. Now, I’ve made it my mission to share what I’ve learned about aromatherapy with my friends, family, and the world. Because - life is so much better with health, happiness, and community.
