Who are the notable collaborators with Brian D Smith in the field of grief healing?

Several people frequently collaborate with Brian D. Smith around grief, healing, and afterlife evidence, mainly through podcast conversations, summits, and joint appearances. A few notable ones include:

• Mark Anthony – psychic medium, attorney, and co-host of The Psychic and the Doc; Brian joined him and Dr. Pat Baccili for an in-depth discussion on transforming grief into growth.
• Drs. Gloria and Heidi Horsley – grief experts and hosts who featured Brian as a bereaved dad and author of Grief 2 Growth to share ideas for living with grief and finding meaning.

Those are some of the more visible collaborators highlighted in recent work.

Is there a particular type of collaborator (therapists, mediums, researchers, other bereaved parents) you’re most interested in?
