Who Is Danny Go!’s Daniel Coleman?

Launched on YouTube in 2019 by Daniel and his friends Michael Finster and Matthew Padgett, Danny Go! is a “live-action educational children’s show filled with music, movement and silliness,” the show’s website reads, that “inspires learning and off-the-couch exercise for kids ages 3 to 7.”

In addition to creating the show—which also runs on Netflix—the trio stars in the program, with Daniel playing the titular Danny. The show has even become a family affair with his wife Mindy Coleman playing Mindy Mango.

When Was Danny Go! Star Daniel Coleman’s Son Isaac Diagnosed with Cancer?

Daniel announced in December 2025 that Isaac had been diagnosed with cancer in his mouth.

“TBH, we always knew this day was coming, as it’s a near certainty w/ Fanconi anemia,” the content creator shared on Instagram at the time. “But it’s definitely hitting a little earlier than we hoped and is still just such a shocking thing to hear about your child, even if you’ve braced for it for years.”

According to the Cleveland Clinic, “Fanconi anemia is an inherited condition that happens when certain genes mutate.” It “may cause physical differences and blood disorders that lead to bone marrow failure,” the medical center notes, and it can cause increased risk of cancerous tumors.

After Isaac was born in October 2011, Daniel documented his son’s many hospitalizations and surgeries—including bone marrow and kidney transplants—on social media and used his platform to raise awareness for causes close to his heart, such as the National Marrow Donor Program.

As part of Isaac’s cancer battle, the teen underwent an 8-hour procedure in January. The following month, Daniel gave an update on Isaac’s health.

“He’s officially stage 3, although the docs said he’s right on the edge of stage 4 because of the speed and aggression of the spread,” he wrote on Instagram. “So even though the visible cancer has been removed, there’s a very high chance that it’s still present microscopically & we’ll have a tough decision to make soon. Because of several Fanconi-related complexities, Isaac’s treatment options are much more limited than in typical pediatric cancer.”

In April, Daniel noted that Isaac’s cancer had “continued to spread aggressively and his energy levels have dropped very low.”

“We’re in the midst of a short palliative radiation round right now to slow down the growth of a large mass under his right eye, but we’ve shifted into a comfort-focused approach with him overall,” the father added. “He has a hospice team onboard now to help manage the pain & we are just doing our best to make each day as enjoyable and restful as possible for him.”

Did Danny Go! Star Daniel Coleman’s Son Isaac Have Any Siblings?

Four years after Isaac was born, Daniel and Mindy welcomed their son Levi. And the kids formed a fast bond—with Daniel noting in a birthday tribute to Isaac that year, “Pretty sure your little brother already thinks you’re the coolest, too.”
