Astrologers may have niche areas that they study and practice the most. I consider myself a natal chart expert. We cannot understand transits without fully understanding the blueprint. By reading for hundreds of clients internationally, I have determined patterns and themes that emerge from particular placements while also managing to individualize each reading.
Natal chart placements also can mean different things for people at different times depending on age and the current cycle you are experiencing. In addition to the natal chart, I use the solar return chart to identify nuances and differences that may occur for the year following our birthday. Astrologers are constantly testing theories and practing. Below is my certification from the Astrology School for chart rectification practices for missing birth times.
