Here's why it's hard to confirm:
* Privacy: Information about personal education and training is often private.
* No Public Statements: Vanzant hasn't publicly stated that she's studied at Landmark Education.
* Focus on Different Areas: While both Vanzant and Landmark Education focus on personal development, they approach it through different methodologies. Vanzant's work is primarily rooted in spiritual guidance and self-discovery, while Landmark Education focuses on leadership, communication, and personal transformation through specific techniques.
It's important to rely on confirmed information and avoid speculating about someone's personal development experiences.
