My name is Chris Brennan, and I am a professional astrologer from Denver, Colorado, USA.
I was educated at Kepler College, where I focused on cross-cultural comparisons between the astrological traditions. I have a special interest in the history, philosophy, and practice of ancient astrology, and I specialize in the Greco-Roman tradition of astrology known as Hellenistic Astrology.
I am the former President of the Association for Young Astrologers, and the former Research Director of the National Council of Geocosmic Research. I’m currently an associate editor of The Mountain Astrologer magazine, and I also serve on the board of Kepler College.
I have written a blog called The Horoscopic Astrology Blog since 2007, and in 2012 I started recording a weekly podcast called The Astrology Podcast. I’m also active in my local community, and in 2008 I founded an astrology group that holds monthly meetings in Colorado called The Denver Astrology Group.
The initial focus of my astrological studies for several years was in the modern western tradition of astrology, although eventually I became deeply engaged in the study of the older Hellenistic, Indian, and Medieval astrological traditions. The basis of my approach at this point is largely rooted in the techniques of Hellenistic astrology, although I also draw on my background in modern astrology regularly, for example by incorporating elements such as the outer planets.
I published my first book in February of 2017, which is titled Hellenistic Astrology: The Study of Fate and Fortune. I also teach online courses on astrology with students from around the world, and I offer certification through my course on Hellenistic astrology.
