About SONO

We build houses, portfolios, and people.

SONO started as a development company and grew into something bigger: a team that develops property, manages rentals, represents clients, lends and borrows with investors — and now teaches everything it has learned along the way.

The Founder

James Sudarsono

Founder and developer at SONO Group, managing member of SONO Equity LLC, and a licensed agent with Keller Williams (DRE #01974200). James has spent years on every side of a real estate transaction — buying, selling, building, renting, and lending.

He is also a pastor, and that shapes how SONO operates: wealth is something you steward, not just something you accumulate. That conviction is why SONO's first course opens with the Parable of the Talents — and why the goal of every SONO engagement is a family positioned to pass something on.

"The first home starts the chain. Everything we do — the courses, the representation, the investments — exists so the chain of wealth continues."
