David has been helpful in keeping my migraine headaches at bay, as well as getting my hair healthier and thicker! There truly aren't any words that can properly describe my appreciation and gratitude for David, yet I'll make an attempt. He has a seemingly infinite knowledge of every aspect of holistic health. Sometimes he would check in to see how I'm doing and with my response  he would have advice for me, where I didn't even know there could be advice. He is an excellent communicator and he truly does care about my success. I am forever grateful for his ongoing support.
