Bill Nastasiak first became interested in astrology in late 1969 when a relative gave him a copy of Edgar Cayce's biography, "There Is A River." In the second part of that book, Cayce suddenly expands the scope of his readings beyond simple medical diagnoses to include references and material about metaphysical subjects, including astrology. This immediately led Bill to a lifelong interest in the subject. A few years later, he took lessons from a student of Eugene Moore, and continued an avid interest thereafter. Currently, he is a student in Noel Tyl's Master's Course.

Bill has attended at least nine major astrology conferences and three long-weekend intensives for Noel Tyl's students. He holds a BS in Organizational Behavior, and is a retired consultant to major organizations throughout the country on topics such as training, teambuilding, leadership, strategic planning, facilitation, etc. He’s also been a mediator in the Maricopa County Justice Courts, as well as within the Alternative Dispute Resolution Program for county employees.

Bill has served on the Board of the Arizona Society of Astrologers as Program Director, Treasurer, and President. He lives in Phoenix with his wife, Mimi, and their dog, Buddy.
