About Us
Hillside Books was founded from hands-on experience in the trades and a passion for simplifying complex accounting challenges for home service companies.
We’re a small, U.S. bookkeeping firm that’s big on personalized service.
We’re here to build real relationships with the contractors, tradespeople, and service business owners we support. And we plan to keep it that way.
We specialize in bookkeeping for home service businesses: HVAC, plumbing, electrical, and other trades, so we speak your language. We know what we’re looking at when we dive into your books, and we know how your systems should work. As a ServiceTitan Certified Partner (STCP), we don’t just plug in numbers, we dig in, fix problems, and help everything flow smoothly between ServiceTitan and QuickBooks Online.
We believe in clarity, accuracy, and transparency.
That means:
No offshore subcontractors, your work stays 100% in the USA.
No bait-and-switch pricing, what you see is what you're likely to actually pay.
No “churn and burn”, we take a thoughtful, high-touch approach to every client.
Accuracy you can trust, because your decisions depend on clean financials.
Monthly 1:1 meetings included, so you’re not just getting reports, you’re gaining insight.
At the end of the day, we want your service business to be profitable, sustainable, and balanced, because balance isn’t just for the books!
Owner, Hillside Books
I’ve always had a thing for numbers, ever since I earned my first bookkeeping certification at 20, I was hooked.
I studied accounting at Santa Monica College and expanded my business education through UCI, earning an HR Officer certification along the way. I’m always learning, whether through formal training or podcasts like Planet Money, The Economist, and The Accounting Podcast. If it sounds boring to most, I’m probably listening on 1.5x speed.
My goal is to help home service business owners, build profitable, sustainable businesses and have the time to enjoy the life they’re working so hard for. After all, balance isn’t just for the books.
I’m based in beautiful Napa, California, come visit and let’s grab a work meal together sometime!

I’ve always had a thing for numbers, ever since I earned my first bookkeeping certification at 20, I was hooked. That early spark led me through seven years in personal and business lending, where I got a front-row seat to how financial decisions shape real businesses.
Eventually, I made the leap to public accounting and climbed the ranks to become head accountant at a CPA firm.
But it wasn’t until I became the controller for an HVAC business in California that I really found my niche. During my time there, the company switched from outdated field management software to ServiceTitan, a powerful tool for trades businesses like HVAC, plumbing, and electrical. While the onboarding offered a foundation, it lacked guidance on how to integrate ServiceTitan with QuickBooks Online (QBO), a crucial step for accurate financial reporting and cash flow management.
To solve this, I worked with a consultant, learned the ins and outs of ServiceTitan, and built the proper accounting structure needed for reliable bookkeeping. That experience highlighted a major industry need: skilled bookkeeping support for trades and home service businesses using ServiceTitan and QuickBooks Online.
Learning the ins and outs of the home services industry and how tools like ServiceTitan and QuickBooks Online could work together, lit a fire in me. That’s where my passion for helping contractors and service businesses truly began.

Hillside Books Bookkeeping was founded from hands-on experience in the trades and a passion for simplifying complex accounting challenges for home service companies.
While working as the controller for an HVAC company in California, I helped lead the transition from outdated field management software to ServiceTitan. Through close collaboration with a ServiceTitan consultant, I learned the platform inside and out and eventually became ServiceTitan Certified.
Soon after, other HVAC, plumbing, and service contractors began reaching out to me for help with the same challenges.
That’s when Hillside Books began to grow, becoming a trusted bookkeeping partner for tradespeople across the Bay Area and beyond.
Today, we help home service companies bridge the gap between operations and accounting. From accurate invoicing and payroll to full ServiceTitan–QuickBooks Online integrations, we ensure your books reflect the real story of your business. Along the way, I became a ServiceTitan Certified Accountant, further solidifying our expertise in this niche.
At Hillside Books, we make bookkeeping simple, accurate, and tailored for the trades, so you can focus on running your business while we keep the numbers working for you.
