Hi, I’m Adrian — a CPA with over 15 years of experience across Big 4 public accounting and private industry, and the founder of Flowline Accounting.

Over the years, I’ve worked in environments where precision, documentation, and financial discipline truly matter. But I also saw how overwhelming bookkeeping can feel for small business owners, especially when you’re juggling everything else.

As a father of two boys, I understand how busy life can be. That’s why I built Flowline to provide steady, dependable support, so your books are handled properly, and your attention can stay where it’s needed most.

Why the name Flowline?

As an avid mountain biker, I chose the name “Flowline” because it’s a type of trail that’s intentionally designed to move smoothly, steadily, predictably, and built with care. That’s how I believe your finances should feel. Not chaotic. Not confusing. Just organized, flowing, and under control.

When we work together, you won’t be passed off to a rotating team. You’ll work directly with me, someone who takes your numbers seriously, communicates clearly, and cares about getting it right.
