Marcia Starck has been working in the field of Astrology and Healing for over 30 years. She began research into Medical Astrology in 1971 when she found that so many of her clients had symptoms that could be relieved by preventive health care, if they understood their symptoms. Her studies in Nutrition took her to North American College in San Rafael, CA where she studied Anatomy and Physiology as well as Advanced Nutrition, writing a paper on the various nutritional approaches to Cancer. She studied Herbology through many retreats and seminars at the California School for Herbal Studies in Forestville, CA.

After her first book, Astrology-Key to Holistic Health, was published in 1982, she studied flower essences, crystals and gems, and aromas. In 1985 and 1986 she lived in the Sierra foothills in California, studying with herbalists, the Flower Essence Society in Nevada City, and working with crystals. At this time, she wrote Earth Mother Astrology (re-printed as Healing with Astrology - 1997). She also wrote The Complete Handbook of Natural Healing (re-printed as Handbook of Natural Therapies - 1998).

Throughout the 1970's and 80's Marcia traveled extensively lecturing and doing workshops at various conferences in the United States, Canada, and Hawaii. She did consultations for many clients and began telephone consultations as a way to maintain her clients in other areas.

In 1987 another phase of work was begun - rituals and ceremonies for women at different stages of their lives. The first Crone Rite of Passage for women at Isis Oasis in Geyserville, CA took place in October 1987, and the first Dark Goddess Retreat, also at Isis Oasis, in October 1988. Currently, she conducts ceremonies for equinoxes and solstices as well as summer retreats near Santa Fe, NM and in other cities in the US and world. In 1993 two books were published, Women's Medicine Ways-Cross Cultural Rites of Passage, and The Dark Goddess-Dancing with the Shadow. These were followed by The Dark God-Exploring the Male Shadow in 1995. Retreats for both women and men are also held in Santa Fe and other areas.

Since 1992 Ms. Starck has resided in Santa Fe, NM. She does consultations by telephone and in person focusing not only on Medical Astrology, but also general Astrology with an emphasis on psychological and spiritual aspects as well as Astro-CartoGraphy (working with locations for both residence and travel), and Relationship Astrology. She also teaches classes on Medical Astrology and conducts seasonal rituals and summer retreats. In the near future, she will be working in Brazil and Europe.
