Shamere McKenzie is a consultant, activist, subject matter expert on human trafficking and a sought-after award winning internationally recognized speaker and trainer.

Her lived experiences with sex trafficking have been featured in several books including a college textbook focused on social justice. In addition, her story has been featured widely, on television, radio, documentaries, and in blogs.

Her strong determination, passion for success and her faith in Jesus Christ helps her to keep her eyes on the prize.
