Accounting, Tax & Advisory for Cannabis & Psychedelics
At Calyx CPA, we provide accounting, tax planning, business structuring, and bookkeeping services tailored to the unique challenges faced by cannabis and psychedelic ventures.
About Us
Calyx CPA was established in 2019 when CPAs Bryant Zwart and Jamie Jorgenstone partnered with Justin Botillier to expand his cannabis focused tax practice into a specialized firm serving emerging plant medicine industries nationwide.
Justin has been self employed as a tax and accounting professional since 2006. In 2016, he sold his general practice to focus full time on working as a partner in Oregon’s burgeoning cannabis industry. That firsthand experience inside a regulated cannabis business shaped his understanding of the operational, tax, and compliance realities facing operators in the space.

Compelled by Justin’s journey and the complexity of the industry, Jamie and Bryant, both formerly with a large regional accounting firm, joined him to build a CPA firm dedicated to serving cannabis and psychedelic businesses. Together, they formed what is now a nationwide firm focused exclusively on providing tax, accounting, and strategic advisory services to these highly regulated and rapidly evolving industries.
