The Perot Museum of Nature and Science is Dirk Nowitzki’s happy place. He and his wife, Jessica, and their three young kids love to visit the dinosaurs and taxidermied wildlife, virtually race the cheetah and dig for faux fossils. “They have a blast there,” the retired Dallas Mavericks great said of his 8-year-old daughter and sons, 6 and 5. The family avoids peak hours so that the giant among Munchkins doesn’t add to the happy chaos. So it was a slam dunk when the museum asked Dirk and Jessica to be brand ambassadors for the yearlong celebration leading up to the museum’s 10th anniversary bash this fall. “This was a great fit for us,” Nowitzki said in a recent Zoom interview. “The kids are absolutely hooked. It’s a great, great space to learn. It gets kids engaged, and they learn without really knowing that they’re learning.
