Our Story

The Greenhouse of Walled Lake opened in 2019 as Oakland County’s first licensed medical dispensary and quickly became a leader in Michigan’s cannabis industry. From day one, our focus has been simple: quality products, education, and community involvement. In March 2020, we made history again as the first recreational dispensary in the county—just as the world changed. With COVID-19 forcing shutdowns, we adapted overnight, launching one of the state’s most efficient curbside pickup operations, serving 1,000+ customers per day without missing a beat.

Since then, we’ve remained proudly independent and locally owned, free from corporate influence. That independence allows us to prioritize people over profits, focus on quality over expansion, and invest in our customers and our community. Today, The Greenhouse is a thriving destination for cannabis enthusiasts and first-time users alike, built on trust, service, and a commitment to doing things the right way.

Who We Are

We’re Michigan cannabis people—advocates, educators, and experts. Owner Jerry Millen has been on the front lines of cannabis legalization for over 15 years, fighting for patient access and better laws long before opening The Greenhouse. That passion for the plant and its benefits runs through every team member.

Our independent ownership gives us the freedom to do things differently. We curate only the best products from Michigan’s most trusted growers, ensuring clean, lab-tested cannabis. Our staff is here to educate, not upsell, providing honest recommendations tailored to each customer’s needs. Whether you’re looking for relief, relaxation, or guidance, we take the time to ensure you feel comfortable and confident in your choices.

Unlike corporate chains, we answer only to our community, not investors. That means every decision—from the products we carry to the events we host—is made with our customers in mind.

Our Community

At The Greenhouse, our customers are our community. We’ve proudly served over 200,000 medical patients and recreational users, from first-timers to seasoned cannabis enthusiasts. Our visitors range from young professionals to retirees, veterans, teachers, and even seniors looking for natural relief.

What sets us apart? Personalized service and real expertise. Customers return not just for our top-quality cannabis but because they know they’ll be treated with respect and care. We take pride in educating and empowering our customers—ensuring they leave with exactly what they need and a better understanding of how cannabis can enhance their lives.

Local Impact

Being locally owned means giving back matters. The Greenhouse isn’t just a dispensary—it’s a pillar of Walled Lake. We take pride in initiatives that support local families, revitalize our city, and create meaningful experiences.

This isn’t just where we do business—it’s where we live, and we’re committed to making a difference.
