From EDM to ‘I do’
For Fiske Planetarium off-site education lead and CU Boulder astrophysics alumna MacKenzie Zurfluh, the famed dome isn’t just where she works, but where she found love
Did MacKenzie and Tanner Zurfluh fall in love and get married because of Fiske Planetarium? Not exactly, but it is where they met and it is where she works, plus Tanner is frequently there helping out at various events. So, credit where credit is due, let’s say that theirs is a Fiske love story.
It began in October 2018, when MacKenzie was serving in the U.S. Air Force and stationed in South Dakota, and Frederick native Tanner was living in Boulder with several roommates who attended the University of Colorado Boulder.

With all due respect to South Dakota, “there wasn’t a lot to do there when you’re 19 and living on base,” MacKenzie says. So, she and her then-boyfriend decided one weekend to drive to Denver for an electronic dance music (EDM) show at Red Rocks and scouted around for something to do the other evening of their visit. They happened across the ILLENIUM laser show at Fiske.
Meanwhile, one of Tanner’s roommates knew someone on the Fiske production team, and that friend of a friend got tickets to the ILLENIUM show for the group.
So, that was how two 19-year-olds who didn’t know each other—one of whom had a boyfriend that she would break up with a week later—ended up at the same Fiske Planetarium EDM show on the same evening.
The show was great—“because all shows at Fiske are,” says the unbiased MacKenzie—and afterward most of the audience migrated to the lobby to chat and make new friends. Tanner was in one amorphous circle and MacKenzie was in another, and eventually the two circles merged.
The closest they came to actually talking, though, was when MacKenzie complimented the jersey that one of Tanner’s friends was wearing. And that was it.
“But we kept running into each other,” Tanner recalls.
Because of the aforementioned South Dakota issue and the fact that Colorado’s Front Range is an EDM hub, MacKenzie drove down most weekends and kept happening across this guy whose name she couldn’t quite remember.
Tanner, however…
After an EDM show at the Ogden Theater in December 2018, Tanner waited outside the theater for 45 minutes to see if she’d come out, not knowing she’d already left.
“My friends had to drag me away,” he says. “It was the first night we talked, and I remember thinking, ‘Come hell or high water, she is going to be my wife.’”
A few weeks later, at the 2018 New Year’s Eve Decadence festival at the Colorado Convention Center, MacKenzie walked up to a group and put her arms around the two nearest people, one of whom happened to be Tanner.
By that point, she remembered his name. SnapChats were exchanged. They were officially Talking with a capital T—not dating, but it wasn’t 100% platonic, either. “After we’d been talking for a while, he looks at me and says, ‘Were you at Fiske on this day wearing this color beanie at this show?’” MacKenzie says.
On Feb. 4, 2019—yes, they remember the exact day—they decided: We’re doing this.

Black holes and relativity
In the beginning, MacKenzie left base on Friday afternoon, arrived in Boulder late Friday night and drove back to South Dakota Sunday afternoon. Tanner made the trip north a few times, but they both agreed there was more to do in Colorado.
However, she was also getting ready to deploy to the Middle East and tried to give Tanner the ol’ “Go live your life, don’t worry about me.”
“And I remember he goes, ‘That’s fine if you don’t want to have a relationship, but can I still be your friend?’” MacKenzie says. “That gave us the opportunity to build a really strong friend foundation. There were times over there where things sucked, and I had him to talk to.”
When she returned from deployment and planned to exit the military, MacKenzie knew she wanted to pursue a degree but wasn’t sure where. On the cusp of returning home to California, Tanner offered her an alternative: “Come live here,” she remembers him offering.
Without MacKenzie knowing it, he’d spent months finishing his mother’s Boulder basement. She could live with him there and study astrophysics at CU Boulder, which is what she did. In the middle of earning her degree, while she was going to school full time and working as a server at a brewery in Longmont, she applied for a job at Fiske and got it.
“I wouldn’t be making as much, so I was really worried about how I was going to pay my bills, but I kept thinking that NASA doesn’t care if I was a waitress, they care if I worked at Fiske,” she says.
“You were chasing your dreams,” Tanner adds. “Studying space and being in the field was always the goal.”
“So, he said to me, ‘We’ll figure it out,’” MacKenzie finishes, and that’s what they did.
In class she was studying black holes and relativity, and at work she was helping them come alive. And in the middle of all this, on the last day of finals in May 2022, kneeling in the chaos of their home remodel—because they’d bought a house in Dacono—Tanner proposed.
She said yes, but with the caveat that they couldn’t even think about planning a wedding until after she graduated—which she did at Fiske Planetarium in May 2024. Seven months later, their wedding in California was essentially Fiske West because so many of MacKenzie’s colleagues attended.
“Our director (Professor John Keller) calls Tanner a Fiske in-law,” says MacKenzie, who is now the Fiske off-site education lead. “Any time there’s an event, he’s here helping.”
“It’s great to be part of the Fiske family,” says Tanner, who co-owns Jayhawk Tile LLC. Fiske has been part of many of their important moments, MacKenzie adds, and in fact her colleague Amanda Wimmer Flint, Fiske on-site education lead, programmed the ILLENIUM show at which they unknowingly first “met.”
Now, sitting in MacKenzie’s office in the depths of Fiske, Tanner can be honest: “As cheesy as it sounds, I fell in love with her smile and her laugh. I genuinely felt a connection.”
MacKenzie beams at him and gestures to her left. “And it happened right out there.”
