The best way to find a good astrologer is to get recommendations from a friend.
Astrology is all about the interpretation. You could go to 50 different astrologers and they would all have a different “take” on your chart. It is a lot like reading music. Fifty musicians would all have their own style of playing the same music. A good astrologer will never predict your future. However, they call tell you the upcoming “weather” patterns. For certain, astrologers can see when storms are approaching, or when there will be long periods of sunshine. The client just needs to be prepared, but it doesn’t mean anything bad or good will necessarily happen. Certainly during the storms, things are not as easy. And during the sunny days we should “make hay while the sun shines”. Stay away from anyone who makes broad pronouncements like, “You will always have trouble finding a mate because of Saturn in your 7th house of marriage”. These are very damaging statements and not true. We are here to learn lessons. If you learn the lesson, you don’t have to learn that lesson again. The whole idea is to literally outgrow your chart. The chart just points to the lessons and to the gifts. We are to focus on the gifts, so we hopefully flow through life in an easy manner. And we are to learn the lessons so we can tick them off and never do them again.
