Drs. Ralph & Lahni DeAmicis both began practicing Astrology professionally in the 1970's, and they expect to 'get the hang of this stargazing thing' pretty soon. They met in the physics lab at Princeton University at the first presentation of the Project Hindsight Research in 1994. This also introduced them to the wonderful circle of Astrologers, connected with the Princeton Astrological Society and the National Council for Geocosmic Research (NCGR) in New York City. These events had a profound influence on their future professional work. They became the Astrologers for the Planetary Calendar in 2002, when Lahni's daughter, Carole, purchased the project after the passing of the founder. Since they had written Astrology columns for magazines, they convinced Carole to let them include a forecast. She agreed but wanted it to be a 'global' forecast, one that looked at the influences of the ongoing Transits, rather than a generic Sun Sign column.

This turned out to be wildly popular since it was much more helpful, and the forecasts have continued ever since. All Astrologers bring their personal interests to the field, and Ralph & Lahni added natural healing and environmental design to the mix. As Master Herbalists and Naturopathic Physicians they wrote 'The 10 Minute Herbalist' book series. They are also well-known speakers and consultants on Feng Shui and Ergonomic Design, creating their 'Feng Shui and the Tango' trilogy and other books on Ergo Dynamics. This expertise shows up in the Calendar's healing system, 'The Terra Houses', Feng Shui and even some Health Hints. In 2005 their 'little tribe' relocated from Philadelphia to Sonoma and Napa California, the gorgeous, sunny wine country at the north end of the San Francisco Bay. The initial reason was for a book project about the winery architecture for their design series. That project morphed into a winery tour book that has spawned its own series.

After speaking internationally for many years on their various topics, the two loved their new home so much, they did not want to leave.
