I've had the good fortune to have many mentors and friends who have inspired me and my work. Outside of studying on my own, my very first teacher was Stephanie Austin here in Washington state. Some astrologers whom I resonate with most today, employing techniques similar to my own, include Robert Hand, Gary Christen, Demetra George, and Bernadette Brady. I've studied the work of many other astrologers, and a number of different systems, and though I may not agree philosophically with all methods or systems, I am grateful for what I've explored and extracted. To me, there is almost nothing less palatable than when a practitioner criticizes the work of another without bothering to take the time to learn the system or method they choose to dismiss.
Astrologers, modern and historical, whose work I recommend: (abridged list) Chris Brennan -and his course on Hellenistic Astrology, Deborah Houlding @ Skyscript, Benjamin Dykes, James Herschel Holden, Charles Jayne, Reinhold Ebertin, Alfred Witte, Jean-Baptiste Morin (Morinus), Firmicus Maternus, Vettius Valens, and Ptolemy. Non-astrologers include: James Hillman, Thomas Moore, Chögyam Trungpa, and Anam Thubten.
