Diane Hollman is a mother, author, and seasoned business development leader with decades of experience in pharmaceutical clinical research and board-level service. She currently serves as Chief Hummingbird (Chairman of the Board) for Caregivers of Mother Earth, supporting regenerative and heart-centered global initiatives.

Diane’s professional path has included leading-edge research in mental health addiction, sleep disorders, rare disease, and psychedelic studies in mental health. She has also assisted in the training of clinicians in the EMBARK method, a pioneering model for psychedelic-assisted therapy. Earlier in her career, she worked in cardiovascular medicine, supplying tools for open-heart surgery and the cardiac cath lab—offering her both a literal and spiritual understanding of the human heart.

She is the co-author of Lost but Never Gone, a tender collection of true stories honoring love’s endurance beyond loss.

Now, as the Ambassador of the Heart, Diane devotes her life to guiding others into centered living and remembrance, and a deep, living relationship with the intelligence of the Heart. Her work bridges the rigor of science with the radiance of spirit, reminding each soul she meets that the Heart is not a metaphor, but a living voice, a guiding home, and a portal into presence.
