ABOUT
Our Story
Axiom was founded in 2017 by David Castaneda, a Colombian native CPA licensed in the State of California.
​
He identified a service gap between traditional accounting firms and their clients, and he decided to start an accounting firm that would fill that gap. ​Since then, we've slowly grown our practice in a way that we can still provide the same level of detail and attention that each client deserves.
​
Today, we're a small team of 5 (and hiring!) focused on providing excellent service and added value to our clients.
