Dr. Leonard G. Horowitz, the esteemed and internationally known consumer health activist, researcher, educator, author and filmmaker, wrote:“Among the many successful coaches and Internet marketing consultants I have known, Mary Henderson beats them all for knowledge, integrity, outstanding communications, commitment to continuing education and human service, and overall benefit from the relationship. I think the main reason Mary is so successful, and a joy to work with, is that she most sincerely cares about contributing more than she receives. She is the best of the best, and it has been an honour and blessing to witness her in action.”
