Reddit mentions of Discount Armageddon (InCryptid Book 1)

My music teacher from grade school was fond of saying that professional ballet dancers have air time exceeding that of professional basketball players.

Also since you created such a perfect segue, there's a book series where one of the main characters is a professional dancer/monster hunter/cryptozoologist. Discount Armageddon: Book 1 of the InCryptid Series

Seanan McGuire's Incyrptid series' Verity Price is what popped into my head first. A little snarkier than the people you mentioned, but still pretty upbeat and funny. Via Amazon:

Ghoulies. Ghosties. Long-legged beasties. Things that go bump in the night... The Price family has spent generations studying the monsters of the world, working to protect them from humanity—and humanity from them. Enter Verity Price. Despite being trained from birth as a cryptozoologist, she'd rather dance a tango than tangle with a demon, and is spending a year in Manhattan while she pursues her career in professional ballroom dance. Sounds pretty simple, right? It would be, if it weren't for the talking mice, the telepathic mathematicians, the asbestos supermodels, and the trained monster-hunter sent by the Price family's old enemies, the Covenant of St. George. When a Price girl meets a Covenant boy, high stakes, high heels, and a lot of collateral damage are almost guaranteed. To complicate matters further, local cryptids are disappearing, strange lizard-men are appearing in the sewers, and someone's spreading rumors about a dragon sleeping underneath the city...

Discount Armageddon is the first installment of the highly praised InCryptid series.
