Even though she never planned to be an author, Maria Yeager began writing books in 2009. She was born in Cincinnati, Ohio and received her BS in Microbiology from Eastern Kentucky University. In 1988, she began her long career at a laboratory technologist and eventually specialized in cytogenetics. During those years, she became interested in alternative medicine, so she pursued and received a Master in Holistic Nutrition and a Family Herbalist Certificate. However, a back injury changed the course of her life, and she had to leave her full-time job. While she was under medical treatment for her back, she wrote her first tea book, Maria's Mixes - A How-to Guide on Making Your Own Herbal Teas, during her spare time. The overwhelming response to this book propelled her to write more books, and today, she writes as much as she can and is happy to be called an author. Maria writes mostly about her own life experiences, and all but one of her books are non-fiction. The most important project in her life is her work on adenomyosis, a uterine disorder similar to endometriosis. Maria personally suffered from adenomyosis for seventeen years, and she did not receive a correct diagnosis until after her hysterectomy. She now helps other women and works as a patient advocate. In addition to two books she has written on the subject, she has also petitioned the NIH for more funding, and she has sent numerous petitions to research institutions asking for the development of more well-controlled studies on the disorder. Additionally, she runs her own website, "Adenomyosis Fighters," and she has her own support Facebook page where she has over seven hundred followers.
