A town of owners
Diamond Bar is white-collar to its core — household incomes well above the regional average, and roughly one in seven residents running their own business. The biggest sectors here are health care and professional services: practices, consultancies, and firms, many of them run from a home office off the 57/60. These are owners who expect their numbers to be right and readable. That's the standard I keep.
What I do for local businesses
What I see in local books
Home-based consultants and professionals have one recurring problem: business and personal expenses sharing the same accounts. It's the single most common thing that goes wrong in owner-kept books — and the first thing a lender, a partner, or the IRS notices. Clean separation, every month →
Medical and dental practices need two specific things done right: clean owner-compensation handling, and books a lender or a partner can actually read without a translator. Both are daily work for me.
Quiet, accurate, and explained in plain English — the way a professional's books should be.
Most monthly engagements run $225–$900/month · one-time books review $275–$800 by business size (credits in full toward your first month) · the 15-minute call ends with a real number, not "it depends."
"He cleaned up my books and continues with the monthly bookkeeping service so I can concentrate on other aspects of my business."

I need books a lender or partner can read — can you do that?
