About Us


Opus is the brain child of Candy Yu, a financial veteran in the charter school community.

About Us



As the owner to Avolon Accounting & Charter CFO Services (AABS LLC), Candy Yu has been a leader in providing high-end accounting back-office support and CFO strategic planning services since 2001 for clients in both California and Georgia. Avolon Accounting & Charter CFO Services’ focus has been primarily non-profit and government agencies. Since 2009, AABS LLC has been heavily involved with GA public charter schools and has become the largest financial service provider within Georgia’s public charter school space in 2019.


To make business operations more efficient for AABS LLC and its clients, Candy incorporated virtual platforms in the mid 90’s and has continued utilizing technology advancements to improve efficiencies. Opus’ concept was born in 2016 as Candy’s attempt to create a more automated solution to improve internal financial operations, budgeting, reporting and modeling. While creating this original software, additional research suggested a much broader application to address the efficiency and quality issues for charter petitions/applications and pre-planning (year 0) processes for all Georgia charter schools. Hence the Opus  ecosystem was created.

Being a school founder and leader is like being a musical conductor. It’s a hybrid profession. Most fundamentally, one is an entrepreneur, an educator, a mentor, a visionary—and mostly, the person who brings everything and everyone into harmony.
