Notes Book


The American Guild of Organists Southeastern Pennsylvania Chapter (SEPA AGO) was first chartered as the Chester Chapter (1961). In 1967, our current name saw to include the wider demographic of our membership base.

Today, one of our most treasured benefits is the built-in camaraderie of a smaller group. Albeit small in size, our scope of membership is a diverse group of organists, organ enthusiasts, organ builders, organ music lovers, and concert-goers spanning a wider geographical area.

Since it’s inception to today, SEPA AGO has striven to present a high quality of lectures, concerts, and workshops pertinent to our organization. These programs aim to reflect a local look at church, theatre, and home organ interests. For a variety of tastes and interests, the calendar (above) spans that palette. Educational, professional, and social events are planned annually, providing a variety of opportunities for growth and sharing. Regular resources include a newsletter, VOX HUMANA, local job postings, and a substitute organist list.
