The Inner Spiritual Center
was founded by Bill Coller and Sharon Siubis. Our mission is to provide intensive and in-depth training for Intuitive and Mediumistic unfoldment and growth. Our goal is for each student to find and achieve their individual potential through classes, ongoing seminars and cross training with Swiss/German Development groups.
A combination of solid knowledge, integrity, dynamic teaching styles and years of experience allow the student an unprecedented foundation in their individual path of learning.
