Mission
To foster the appreciation of chamber music in our region by presenting performances featuring nationally known musicians in accessible and inviting formats, with an emphasis on developing a broad based sustainable audience through education and community outreach.

Six concerts per year by professional chamber music performers to an audience of 300-350 people per concert within a retirement community of approx 9500.
Operating model
- Revenue model
- Donor-supported. 96% of the money available for current operations came from contributions and gifts.
- Distribution model
- Cannot be determined from the filing. The filing does not provide enough consistent spending detail to tell whether the nonprofit works directly or through others.
The verdict
STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Some filed totals do not add up and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
