Founded out of necessity.
Not because the world needed another accounting firm. Because business owners deserved something better from the ones that already existed.
TreeStar Solutions is a women-owned accounting, tax, payroll, and advisory firm headquartered in Chico, California, serving businesses across the state and beyond.
Too often, accounting feels reactive, confusing, and disconnected from what it takes to run a business. Owners chase answers and hear from their accountant only when a deadline is close. We built TreeStar to be different.
We learn how your business actually runs before we tell you what the numbers mean.
We plan for what is coming, not just record what already happened.
Clear answers in plain English, so you can act on them with confidence.
One connected team, there all year, not only when a deadline is near.
Everything orbits your business.
Bookkeeping, payroll, tax, and advisory are not separate services handed off between strangers. They are one system, working from the same information, toward the same goals.
That is how we catch what others miss, plan before it is too late, and give you a clear picture of where you stand.
Release notes for a better accounting firm.
- v0.1 The beginning
Two firms. One North Star.
TreeStar began when two independent, women-owned accounting and tax practices joined forces. Each brought loyal clients, years of experience, and different strengths. Together, the business more than doubled almost overnight.
- v1.0 2022
Building our constellation
We could no longer run like two small practices. We built a team, defined roles, and put real structure behind a much larger client base.
- v2.0 2023
Finding our orbit
We figured out what TreeStar was going to become. We sharpened our processes and moved beyond bookkeeping and tax preparation toward complete business solutions.
- v3.0 2024
Reaching for the stars
As our clients grew, so did our work. Payroll, compliance, entity support, tax strategy, and advisory became the heart of what we do.
- v4.0 2025
Charting a new course
We asked what a modern accounting firm should look like, then rebuilt around the answer: a better client experience, proactive services, and systems that make accounting more useful.
- v5.0 live Today
Stellar growth, solved.
TreeStar looks nothing like the two practices it started as, and that is exactly the point. We keep refining how we work so we can support businesses through every stage of growth.
- roadmap What comes next
Expanding our horizons
Better systems, deeper expertise, and new ways to serve the industries and owners conventional firms overlook. The name started with an accounting firm. The vision has grown much bigger.
Built by women who built it themselves.
TreeStar was founded by women who each built their own accounting practice from the ground up, then chose to build something bigger together.
That path shapes how we work. We know what it takes to start, to grow, and to carry the weight of a business. We bring that understanding, and a meticulous eye for detail, to every client we serve.

OUR COMMITMENT TO YOU DOES NOT.
