Practical Business Advice for Service Business Owners

This is where I write about how to build and run a business. Hiring, pricing, operations and systems, sales process, and leverage. The things that actually move a business forward when they’re done right.

I co-founded Window Tint LA in 2014 and helped grow it to $3M a year before the company was acquired by American Window Film in 2018.

From there, I co-founded Tint Wiz, a CRM for window tint and PPF businesses, built from the internal system we used to run Window Tint LA. We launched in 2019, became the industry leader, and were acquired by Fullsteam in 2025.

Everything I write comes from experience building and operating real businesses, along with helping other business owners improve their systems, sales process, and day-to-day operations. What worked, what didn’t, and how to think through the next move when you’re in it.

If you’re trying to grow a service business, improve your sales process, fix your operations, or make better decisions as an owner, this is for you.
