After studying with Lou for over 15 years, he continues to amaze me with his ability to cut through the story to perceive what truly needs to be healed. His cutting edge materia medica, visual and verbal acuity, and understanding of human nature, make him a teacher unparalleled. His teaching style is stimulating, flexible, and well-paced, with a perfect balance of case presentations, materia medica, and philosophy. While clearly a master homeopath, Lou retains a humility that is refreshing and conducive to learning. My approach to homeopathy has been influenced greatly by Lou and success with my patients always takes another big leap forward every time I am fortunate enough to be able to study with him. The same natural laws that can be seen in the series and stages of the periodic table also underlie the taxonomic system of the enormously varied plant families. The path to the required remedy is not as easy to recognize as with the mineral elements – indeed, it is still evolving! One of the timeless values of this work lies in the essences of the plant families.
