At 13, Nancy Garen, author of Matrix Software's Professional Tarot program, began studying Tarot, numerology, astrology, and just about every other spiritual/metaphysical book or quest she could get her hands on. For the next 10 to 15 years, she continued studying Eastern and Western religions and Science of Mind-type philosophies and meditated a great deal. During this time, she set out to write her first book, Creating Your Own Tarot Cards.

After a stint as a Makeup Artist in the motion picture industry, she soon decided to devote her life to the study and practice of metaphysics. Garen's first "professional psychic" job was at Inner Perceptions in Studio City, and after that closed, she joined Jim Watson at the Metaphysical ESP Center in Los Angeles. Over the next few years, Garen taught Tarot, psychic development, and Numerology.

Garen's years of studying Tarot made her realize that she had to discover the answers herself, that books never answered her specific questions. So she began researching and writing her second book Tarot Made Easy. She interpreted the cards so that they had sections for any categorical question you could think of – love, health, money, guidance, etc. After about 12 years of research, Garen completed her book, which then became the basis for Matrix Software's Professional Tarot program.

After leaving Los Angeles, Garen worked as a radio psychic, continued teaching Tarot and ESP classes, and wrote and published a new workbook called The Tarot According To You.
