our story

Four score and seven years ago, no, no but it was over 4 years ago that the very concept of Green Stem was envisioned. After retiring from the Automotive Corporate world in 2017, an opportunity presented itself for me to re-engage with one of my life’s passions, cannabis.

Our first attempt to break into to legal cannabis world on the east side of the State, failed miserably. However, our family, stumbled upon a small town named Niles, in SW Michigan. We’d never heard of it, but they were accepting applications for two provisioning centers. To our surprise and great joy, we were awarded one of the PC Licenses in Niles. So just like the “Beverly Hillbillies”, we “loaded up the truck and moved…to Niles”. In fact, over a dozen of us east siders, pulled up stakes and headed west. With a lot of effort, hard labor, and my retirement savings GSP was finally established in March of 2020.

I have never been so proud in my 65+ years on this planet than I am of what our family has accomplished. In two+ years we have been able to establish Green Stem as the premier destination in SW Michigan to procure cannabis products and merchandise. I am also proud and very pleased that our families have found our “forever home” in Niles, the new “happiest place on earth”!

As of this writing, Green Stem has expanded to incorporate our new Niles based Grow and Processing facilities at the former Simplicity Patterns complex. You will find our families very own Sticky Mitten Extracts on the shelves now and Simplicity Farm’s Flower soon. I am so much looking forward to Green Stem/Simplicity being a positive force in the revitalization and rebirth of Niles and the greater Michiana area.

What is the difference between placing an Online Order and Curbside Order? 

The difference between the two is in the ordering stage. An Online Order is placed via the Green Stem website before arriving at the store. A Curbside order is completed upon arriving at the store with a GSP Budtender.

Can I pick up my order the day after placing it?

No. All orders must be picked up on the same day they are placed. We do not hold them overnight.

Green Stem is located at 1140 S 11th St in Niles, Michigan. We have parking and entrances accessible from 11th street as well as behind our building on 9th street. The backlot can be accessed from 11th street off Marion street.
