And in the last 10 years, more than 4 million people have attended the children’s museum. The DoSeum is a spinoff of the San Antonio’s Children Museum, which was founded downtown in 1995 by a group of volunteers. Last year, the children’s museum raised $1.44 million dollars and earned $5.17 million in revenue — it spent $5.16 million on educational programming and exhibits. On Wednesday, DoSeum spokesperson Lisa Martin-Bomnskie said the museum doesn’t have specific development plans to share but is excited about the next decade. “The DoSeum is stronger than ever and poised for its next decade, with plans for greater impact on early learning in San Antonio and beyond,” said Menelly.
