12Listen (pronounced “one-two listen”) has its origins as a bricks and mortar New Age store called Twelfth House, located in Denver, Colorado. The name "Twelfth House" refers to the twelfth house in Astrology.

Founder Mark Husson practiced what he termed "Psychological Astrology," as he believed that astrology and intuition could be used as a psychological tool for healing and not simply a way to predict the future.

Twelfth House became popular with those in the medical field as well as psychiatrists and people who understood the value of Husson’s vision. Husson has a Masters degree in counseling and developed a methodology to test psychics to verify their capabilities. With partner John Joseph, Husson took Twelfth House online with a group of screened and tested psychic advisors in order to provide trusted and accurate psychic advice and counsel to everyone who needed it.
