Ostrum worked in Lowville, New York, as a veterinarian at the Countryside Veterinary Clinic (mostly with horses and cows) and as a managing partner with Dairy Health & Management Services as of August 2019.

Ostrum also participated in Veterinarians on Call, a Pfizer-sponsored film series highlighting the work of big animal veterinarians.

Ostrum and several of the film’s co-stars were set to record an audio commentary for a special edition DVD in October 2000.

Wonka co-star Denise Nickerson (Violet Beauregarde) confirmed in a 2010 interview that Ostrum had agreed to join her and Paris Themmen (Wonka’s Mike Teevee) for a reunion marking the film’s 40th anniversary in 2011.
