Robert Bondlow has unexpectedly resigned as the executive director of the Milwaukee Ballet. Bondlow had been on the job for only six months, and neither he nor the company are commenting on the reason for his abrupt departure. The company is in “somewhat precarious” financial shape, but doesn’t expect to run a deficit for the fiscal year just completed. Bondlow had a tough act to follow in Milwaukee: his predecessor, Christine Harris, was widely credited with stabilizing the business side of the organization and making it an attractive group for big-money donors to support.
