Portland Chamber Orchestra dissolves during its 79th season, canceling remaining concerts at Beaverton’s Reser Center

Board votes to end operations and cancel two scheduled performances

The Portland Chamber Orchestra has announced it is dissolving midseason, bringing an end to an organization that dates back to the mid-20th century. The board of directors said the ensemble’s 79th season will be its last and confirmed that the remaining two concerts on the season calendar have been canceled. The organization also stated that Oregon authorities have been notified of the dissolution.

The cancellations affect two performances that had been publicly listed for spring 2026 at the Patricia Reser Center for the Arts in Beaverton: a March 3 program titled “Lion & Lotus: A Festival of Music and Dance” and a May 19 event titled “Banner & Burden: Music and Spoken Word.”

Financial pressures cited; formal wind-down expected later in 2026

In public comments made after the dissolution notice, a board officer described the decision as rooted in financial strain and the difficulty of sustaining operations following the pandemic-era disruption of arts organizations. The board decision to dissolve was described as having been made on January 19, 2026, after the orchestra’s late-December 2025 concert revenue was assessed as sufficient to cover immediate obligations but not the remaining season.

The organization’s statement did not provide a detailed accounting of finances or a comprehensive explanation for the closure. It emphasized gratitude to patrons and musicians and indicated the board’s intention to meet outstanding obligations. The dissolution process was described as involving required notifications to state offices and outreach to grant-making entities to determine whether any awards must be returned. The formal wind-down was described as likely extending into November 2026 as remaining expenses are resolved.

What dissolution means for ticket holders and the nonprofit entity

Ticket refunds for the canceled performances were described as being handled through the presenting venue. For Oregon charities, dissolution typically requires a board vote and a plan for distributing any remaining assets consistent with governing documents and state requirements; nonprofit assets are generally directed to another qualified charitable organization as part of an orderly closure.

History and recent leadership

The Portland Chamber Orchestra was founded in 1946 by conductor Boris Sirpo, who began the ensemble with student musicians associated with Lewis & Clark College. Over the decades, the orchestra became known for chamber-orchestra programming and collaborations.

In recent seasons, the organization listed Deanna Tham as its artistic director. The closure comes before the ensemble’s planned 80th anniversary season.

• Organization status: dissolution announced; remaining 79th-season concerts canceled

The board’s public message thanked supporters and musicians and stated that Oregon has been notified of the dissolution.
