About Derek Oldham, CG ~ Certified Ganjier & Health Coach

Derek Oldham is proud to be the leader of Budtender Education and Training for Cannabis Industry Professionals in Michigan. He has worked in the cannabis industry for 5 years and in multiple states, and has been fortunate enough to travel around the world and experience cannabis culture in 12 countries.


Derek's knowledge and passion for ganja brought him from Oregon to Ann Arbor, Michigan in 2018. He became a budtender as the market transitioned from medical to adult use. He continued to work as a budtender and dispensary store manager throughout the pandemic, helping to provide medicine and support for our community during a difficult time. The people who came in and shared their healing stories about how ganja improved their lives kept him inspired and hungry for more knowledge.


This desire lead Derek to become a Certified Health Coach through the Institute for Integrative Nutrition in 2020. During this time, he worked with City Council and Decriminalize Nature to successfully change the law to decriminalize entheogenic plants and fungi in Ann Arbor. Also at this time, Derek started to cultivate his own medicine that helped keep him strong and healthy-minded while being an essential worker throughout the pandemic and recovering from a bad bout of Covid-19.


In 2021, Derek was accepted into the first Ganjier certification program to become a designated Master of Cannabis Service and an expert in assessing cannabis products. The Ganjier program is the most comprehensive collection of cannabis knowledge currently available, containing both cutting-edge science, and the ancient, forbidden, and nearly forgotten wisdom of the past. He was honored to graduate and receive the title of Certified Ganjier.


It is now Derek's duty and privilege to ensure that this knowledge is preserved, passed on, and expanded upon. He is currently offering Budtender Training Seminars to cannabis industry professionals. Derek created an 8-hour course that facilitates a deep dive into everything that makes ganja such an important and sacred plant for us humans. From the history and culture to the botany and pharmacology, we cover it all. He will teach you how to be confident on the bud floor, help you match patient requests with the right products, and understand the "why" behind it all in a fun, engaging and memorable way.
