"Balancing Hormones Naturally: A Holistic Approach to Women's Hormone-Related Health Concerns" Lecture with Power Point CD. Great Lecture to present to your local community from chiropractic perspective! Never gave a lecture before? No problem, "Complete Guide to giving an Outstanding Lecture" booklet is included. By David Singer Enterprises. Paid over $300 for it at seminar but I am now retired. $50 + $ 7 for shipping. Slightly used but in great condition.
