Southeastern Pa Chapter


Message from the Dean 

Welcome to the AGO Southeastern Pennsylvania Chapter website, where you may find useful and regional information on activities about the grandest of instruments: THE ORGAN. Celebrating our 58th year (established, 1961), we invite you to browse the events calendar and resources here. Informative workshops, educational presentations, performances, tours, social events, and our periodic newsletter, VOX HUMANA aim to support all-things-organ. If you are currently seeking a national professional organization related to organ and choral fields, look no further! Our only criteria for membership is your interest in organ music.

Join us for an event or as a member; we think you’ll stay for the fun.

Yours musically,

Mary Eileen Johnston

Although most of our professional members are church organists, there are many of us who are members for the sheer love of organ music. AGO is “non denominational,” secular, and all are welcome to join as a member, regardless of musical ability. 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.

Members benefits also include The American Organist magazine and exclusive invitations and discounts on all AGO offerings.

For more information, please contact: Nancy F. Brown, Registrar, 610-358-3112
