Sandra Leigh is an "awesome astrologer."  She spends much time doing  research and preparing for all client consultations.  I highly recommend her to "anyone" in search of more information about themselves and the influences the alignment of the planets might have on their lives. Kathleen N., Lafayette, Colorado

Sandra-Leigh really does know her stuff!!! In my last session, my chart clearly showed some upcoming complications and stressful times. Interestingly enough, I was fired, I had an accident, and I attended a funeral! She very specifically told me that I could be fired, have an accident or attend a funeral and all of those things happened! Having the "heads up" really was helpful. And I am very grateful that she does not just tell me what I want to hear (the good stuff!)- but also what to watch out for and when I am entering a difficult cycle. She also told me when things would turn around and I am very much looking forward to next year! I am thankful Sandra-Leigh is so good at what she does and for revealing the good AND the bad. Lisa, Naples, Florida

I've had an interest in Astrology for quite some time now and have explored readings with several different astrologers. Not only does Sandra-Leigh have a very accurate gift of "insight" but I believe her formal education (a Master's degree in Psychology) contributes greatly to her well-rounded and very often dead-on readings. Sandra-Leigh has done several readings for me and they were replete with detailed insights -- NOT generalizations that could be true for just anyone. I recommend Sandra-Leigh highly and with utmost confidence that you will find your reading with her a wonderful experience.

Customer Review by Jeanne Scoville:

As a holistic RN I highly recommend this wonderful, inspiring book, The Magi Within. It has practical guidelines for accessing & fine-tuning one's own natural intuition in everyday life while also encountering a rapidly changing world. I found not only words of wisdom, but also beautiful artwork at the beginning of each chapter...truly a love-filled resource for an awakening humanity.
