Who has Brian D Smith collaborated with on spiritual growth projects?

From the material available, a few collaborations stand out:

• Roberta Grimes – Afterlife researcher and host of Seek Reality. Collaborated through podcast conversations about grief, consciousness, and the afterlife.
• Sue Frederick – Mystic and spiritual teacher. Shared a “mystical conversation” exploring grief as a path to spiritual awakening and self-forgiveness.

Those are documented public collaborations focused directly on spiritual growth and afterlife understanding.
