About Us

Foundation for Human Potential

We awaken the human spirit through creativity, compassion, and love.
Our mission unfolds through four key areas: Teaching, Training, Travel, and Research.

Teaching: Accessible programs on trauma, fear, anger, and self-confidence. From short courses to deep yearlong journeys, our seminars, courses and School of Singularity help adults and children explore self-awareness and personal growth.
Training: We equip facilitators, therapists, and community groups with tools for healing and transformation.
Travel: We lead sacred journeys to places of peace and wonder—like the Cave of Mary Magdalene in France and the St. Michael alignment in England.
Research: We support studies exploring how body, mind, and spirit shape the human potential for joy and longevity.

Our story

Founded by Kamyar M. Hedayat, MD and Tiffany Barsotti, M.Th. the Foundation carries forward the legacy of Harvey Grady, Ph.D co-developer of Personal Self Integration (PSI)—a gentle, powerful path of self-understanding and love. PSI helps each person heal and grow by connecting to their higher self and embracing who they truly are.

Our Inspiration

The Foundation for Human Potential stands on the shoulders of Dr. Harvey Grady, a psychologist, visionary, and lifelong servant of the human spirit. It was created to honor a life devoted to awakening the divine within each person, the courage to know oneself and the compassion to serve others.

Born the son of an Arizona sheriff, Harvey’s path wove through many worlds — from social work and public service to holistic healing and spiritual teaching. His life was a testament to compassion in action.

With his wife Julie Grady, he founded the Center for Human Potential, where they developed Personal Self Integration (PSI) — a joyful, practical approach to self-understanding and healing. PSI invites each person to “know and love yourself” more deeply, guided by your own highest wisdom.

Through decades of service, research, and heart-centered teaching, Harvey helped countless people awaken their inner light. His legacy lives on in our mission to nurture the limitless potential within every human being.
