The Team

Hallock Derickson ("Derek") Davis, CPA
​Founder
​Derek has been formally trained in tax accounting at PriceWaterhouseCoopers LLP (PwC) and Deloitte Tax LLP and has approximately a decade of professional taxation experience. Additionally, he is a Certified Public Accountant and has helped clients throughout the United States.

Derek first became intrigued in the Cannabis tax space in 2010 when cannabis was on the ballot for legalization in California.  What he found most interesting was tax code 280E which disallowed individuals and businesses to deduct ordinary and necessary business expenses. Unfortunately, California wasn't ready for full legalization so he put his interests on the back-burner. 

In 2015, seeing the growth of this industry from the amount of revenue Colorado was able to generate re-sparked his interest in this space and he decided to start California Cannabis CPA.  
His goal is to help individuals and companies in this space identify and apply tax and business strategies to increase their cash flow while making sure they are in full compliance with all applicable rules and regulations.
