Chartered Accountants for the 21st Century


Achen Henderson manages and oversees the integrated and seamless combination of technology, strategic alliances, and in-house expertise to provide our clients with high-performance accounting and tax. We offer a full suite of accounting and tax services you can choose from and, if you prefer, we package these services together to make life simpler for you. Business owners get up-to-date information about their companies, in easy-to-understand terms, so they can make more informed decisions. 

Our Mission

We believe in working better and smarter so that we can truly achieve work/life balance. And we want that for our clients too. The old-fashioned approach of working yourself sick 24/7 to achieve success no longer applies in our technology-driven world, giving those of us who embrace it more free time and more peace of mind.

We begin by engaging in mindful collaboration with our clients so that we can understand their goals and objectives, then tailor our services to help them get where they want to go. We also form strategic alliances for our clients to ensure growth and opportunity.

With Achen Henderson as your partner in success, you have the tools, information, and guidance you need to thrive, grow revenues, manage costs, make more informed decisions, and focus on what matters the most—your customers. Just as importantly, we’ll keep your taxes as low as possible while ensuring you’ve filed on time and correctly.


Our Story

Achen Henderson was formed in 2013, when partners Clayton Achen and George Henderson stepped off the hamster wheel that is the traditional accounting firm. In 2015, Carol Sadler joined as partner, bringing her U.S. cross-border and Canadian tax knowledge to our firm.

We are different because we measure our success based on the success of our clients, and not on how many hours per month we log and who drives the fanciest car. We’ve always embraced technology, but the technology hadn’t caught up to our dreams. Until now…

In 2018, we underwent a firm-wide redevelopment of our strategy, our processes and systems, our why, and our cultural alignment. We decided to focus our entire existence on our clients’ success and we realized that the only way to truly accomplish this was to empower entrepreneurs and business leaders to focus on creating value in their companies.

So our Untangled service package was born. Our base package for businesses of all sizes, Untangled frees our clients’ most valuable (and usually most expensive) resources—people—from data entry and payroll.

We formed a strategic alliance with the most advanced bookkeeping technology firm in the world to ensure that our clients always have access to real-time bookkeeping information. Imagine the power decision makers have when they have real-time and accurate financial results!

But we didn’t stop there…

We realized that simply taking care of data entry isn’t enough in some cases. We wanted to provide decision makers with a view into the future of their company, and a system to measure actual performance against their expectations.

So we created our Unburdened service package. Our Executive Services team works with every one of our clients to determine what drives their business (KPIs), establish advanced management reporting dashboards (also real-time), and develop budgets and forecasts and track actual performance against them.

But we didn’t stop there…

All of the clients we work with have great ideas and growth potential. They are often not business experts and they may have internal process or cultural issues that are holding the company’s growth potential hostage.

Enter our Unleashed service package. We formed a strategic alliance with one of the top leadership and cultural change firms in the world, the Crankset Group, to help our clients take their businesses and scalability to new heights.

With custom service packages build to suit every size of organization, we launched our new cutting age professional services firm – and we’ve never looked back.
