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, as well as the former Research Director of the National Council of Geocosmic Research. I’m currently an associate editor of The Mountain Astrologer magazine, and I write a monthly column for them on auspicious dates for beginning new ventures using electional astrology.
I have written a popular blog called The Horoscopic Astrology Blog since 2007, and in 2012 I started recording a semi-regular 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 traditions. The basis of my astrological 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 conduct consultations using a mixture of ancient and modern techniques, with a focus on timing and prediction. If you are interested in scheduling a consultation with me then please see the list of services I offer on my astrological consultations page.
I also teach online courses on astrology with students from around the world, and I offer certification through my course on Hellenistic astrology. I’m currently in the process of completing my first book, titled Hellenistic Astrology: The Study of Fate.
