Dr. Adam, his family, and friends have used doTERRA products for several years and love the extra that they provide. When asked "Why doTERRA and not Young Living or any of the other brands out there?" Dr. Adam simply stated "They are who I was introduced to first and I fell in love with their product." He went further on saying "Don't get me wrong if you use Young Living or another highly sought after brand that is fine I just prefer doTERRA for my family. If you choose to use essential oils you can learn a lot from all of the major companies and should look outside of your preferred brand, after all you need to know what is out there."
