About AGIO

Senior-Level Expertise. No Junior Staff.

At AGIO, every engagement is handled by a credentialed senior advisor — not passed down to junior staff. We work with a select number of clients to ensure each one receives the attention their financial situation deserves.

Founded in 2021 by Jay Chung, CPA, MST, AGIO was built on a simple premise: business owners deserve the same caliber of tax and advisory counsel that large corporations receive.
