There’s a moment, walking into All Good Dispensary on Avenue H in Flatbush, where your brain does a small double-take. The diner stools. The old drive-in marquee. A microscope — an actual microscope — sitting out on the counter for customers to examine flower up close. All Good doesn’t feel like a dispensary. It feels like a spot your grandmother and your plug both would’ve felt comfortable in. That’s entirely by design.
Shannon Riley and Sean Robinson opened All Good on April 11, just days before 4/20. Brooklyn Paper and News 12 were both there on day one. The neighborhood showed up.
But the real origin story starts much further back — and much further away.
Moonlight, Kayaks, and a Mantra
Sean Robinson’s origin story reads like a Brooklyn indie film treatment. A varsity swimmer in high school, he used the plant to unwind after meets — until the day his coach caught him and kicked him off the team his senior year, killing his scholarship hopes. He joined the Army instead, worked his way to a duty station, got out in 2002, came to New York, went to culinary school, cooked in some of the city’s best restaurants, burned out hard, traveled with his dog on a rickshaw, and eventually landed on a permaculture farm in Texas where he lived in a bus for three years.
“That’s where I really started to understand the healthy growing of food and medicinal herbs,” he says.
When he returned to New England and started a family, he got deep into cannabis cultivation. Clean cultivation. The kind where you paddle a kayak down a river in the middle of the night — soil loaded in the hull — to reach a secluded patch of land, tend to your plants by moonlight, and get out before dawn. That’s not a metaphor. That actually happened.
“We found a plot of land out in the foothills,” Sean recalls. “A river ran through it, no one around. We’d drop our kayaks, paddle down to a very secluded spot, tend to our plants in the moonlight, and be out before daybreak.” The mantra that came out of that era — It’s All Good in the Woods — became the foundation of everything that followed.
Shannon’s path ran a different route. Half Canadian-American, she grew up smoking Vancouver BC weed as a teenager and started a hemp jewelry business at 15, getting into every smoke shop in Houston. She’d been an entrepreneur since she could breathe, she says — and she’d been telling anyone who’d listen that one day there would be weed stores, and she was going to own one. Her friends laughed. She kept believing.
“I always felt it,” she says. “It was this feeling inside my soul for as long as I could remember.”
When she found Sean — specifically, when she was trying to find organic weed in the legacy market and heard about this guy growing it — the connection was instant. She even wrote a film about the kayak story, which she’s since trademarked. Together, they built Pharm.nyc as a CBD brand while they waited out the long road to a THC license. That wait stretched until November 2023.
A Diner, a Drive-In, and a Dispensary
The design of All Good is Shannon’s vision, executed by Sean. Every element pulls from somewhere real.
“I wanted to take from familiar spaces our families have interacted with over history,” Shannon explains. “Diners are places you can bring your grandma, your aunts, your uncles, a date; you never feel unwelcome.” The soda shop stools aren’t just aesthetic. They’re a deliberate nod to a moment in American history when cannabis was prescribed, and you’d pick it up at the pharmacy, often one with a soda counter. Sitting on those stools, they’re re-imagining that.
The marquee letters on the wall came from Shannon’s childhood memory of drive-in movie theaters. Sean designed and built them using greenhouse materials, the same kind used to grow cannabis. The terpene wall is central to the floor layout. “Everything has purpose in the store,” Shannon says. “A lot of it is to educate and bring more conversation around the plant.”
The Green Check
All Good stocks no multi-state brands. None. In a borough with hundreds of dispensaries, licensed and otherwise, that’s a serious line to hold.
“Since I started down this path, I was on a mission to be a destination dispensary in the heart of Brooklyn,” he says. “To do that, I have to go out and seek brands you can’t find at many stores around us or in the five boroughs.”
During the year and a half between submitting their license application and getting approved, Sean was in the field attending events, meeting growers and farmers, visiting farms, and learning cultivation practices. As a legacy East Coast operator, he knows the West Coast has always been the competition. In the legal market, that’s still true. His answer is to give every New York-born brand the shelf space to stand tall.
The payoff is showing up in real time. Since opening, customers who used to ask only about sativa, indica, hybrid, and THC percentage are now having conversations about terpenes, flavor profiles, and effects. “Just to watch the customers grow with our store as they explore the menu,” Sean says, “they’re very excited about all the new stuff we bring.” Some of them, he notes, have stopped shopping anywhere else.
Veterans, Women, and Flatbush
All Good is women-led, veteran-owned, and family-run. On a Tuesday afternoon at the shop, that means Shannon is handling CEO and CMO duties, Sean is deep in operations and inventory, and both of them are doing staff training and customer interactions. Small staff, tight team: “like family,” Sean says.
Sean’s path to plant medicine runs through something harder than a kayak at midnight. He lost his mother at age 2 to a prescription drug overdose. She’d struggled with addiction to pharmaceuticals for years. That loss made him skeptical of pharmaceuticals from an early age; a skepticism that deepened in the military, where he and other service members were given experimental vaccines and injections and watched the ill effects hit within 12 hours. “There’s no course of action to be taken from the ill effects of pharmaceuticals,” he says. “They’re just able to continue to harm us.”
For Sean, cannabis as a plant-based medicine isn’t a business angle. It’s personal.
Shannon comes at it as a parent. The fentanyl crisis in New York City high schools was a real motivator for her to push hard for a licensed, tested dispensary in a highly residential neighborhood that hadn’t had one. “Our community has been very grateful to have a trusted source,” she says. They educate customers regularly on the difference between legal cannabis and smoke shop products: spray packs and unregulated products that have flooded New York.
“The community welcomed us with open arms.”
Cannabis Justice Isn’t Background Noise Here
All Good supports the Last Prisoner Project and talks openly about cannabis justice on their website and in the shop. Over the holidays, they ran a campaign that raised money and brought the community together. For residents of Flatbush who were directly impacted by prohibition (arrested, locked up, fined, policed), walking into a legal shop that acknowledges that history carries real weight.
“It’s very hard for all of us to know that we’re here legally consuming weed and people are sitting in jail,” Shannon says. “And I think the community appreciates being able to have that open conversation. We’re not done fighting for it.”
What’s Next
Shannon has stools in storage (she’s sourced matching ones across the country), and she’s ready for a second location whenever the December licensing queue moves. All Good is positioning itself as a destination dispensary, a place Brooklynites travel to rather than settle for something nearby.
They are expanding cannabis culture beyond retail with All Good Cannabis TV, featuring cannabis yoga and original programming rooted in Brooklyn cannabis culture. The brand recently released its first music video produced with Saint6 Entertainment and will be hosting a 4-20 Mic Drop April 20, 2026 showcasing emerging Brooklyn rappers. “Stay tuned,” Shannon says, with the energy of someone who has been waiting her whole life for this exact moment and has no intention of slowing down.
In Their Rotation
Shannon: “I’m super excited about Harney Brothers’ Butterfly Lemonade, it’s made with butterfly pea flower, which helps with THC absorption and turns it purple. I also love all the flower from 1slice; their graphic design is as good as their product. And right now I’m really excited about the Hunter Melts suppositories from Upstate Mary — there are serious wellness benefits there that I’m looking to educate people about.”
Sean: “We’re finally seeing really good sun-grown come to market. METRC held up a lot of stuff, so that window is always limited. And some of the small micros that are finally getting online are incredibly impressive. Doing a lot of output with a very small dedicated team. Just like us.”
