About Us


The Institute for Spiritual Development Treasure Coast (ISDTC) is a non-profit organization dedicated to assisting each person with spiritual and personal development.

Our mission is to provide a safe and nurturing spiritual home for people from all walks of life to discover and deepen their relationship with the Divine. We welcome those who want to participate in pursuing these goals in a community of love, support and service. ISD Treasure Coast offers educational classes, development circles, spiritual services and special events.  The goal of ISDTC is to support each person's individual spiritual journey by discussing and exploring different perspectives that aim to assist each of us in becoming a better version of ourselves.

Our Parent Organization Institute for Spiritual Development was founded over 40 years ago in Sparta, NJ. ISD has development and education centers located in Washington, DC, Oneonta, NY, Madison, NJ, and now, the Treasure Coast of Florida in Vero Beach. To all who are seeking their individual truth we say,  Welcome Home!

Our Approach


Dedicating itself to the highest standards of achievement, knowledge, and service, the Institute for Spiritual Development recognizes the need for thorough education of its ministers and congregation. All are invited to study within the context of a viable and dynamic education system. To those called to the level of Holy Orders, the Institute offers a vigorous and extensive pursuit for spiritual and intellectual excellence.

The Institute Education Program presents a wide variety of classes, workshops, seminars, and learning experiences to stimulate spiritual growth and personal development.


We believe that all great religions and philosophies contain within them the spark of truth and wisdom that can inspire within us a more complete understanding of our place in the universe. Aided by this belief, we seek to provide a supportive environment through services, spiritual healing, fellowship and education.
