After serving the community for 10 years as owner of Animal ER of Northwest Houston, Jennifer Hennessey sold the business to her colleague, Michelle Winthrow, effective Feb. 20.
According to a statement from the business, Hennessey will continue to work occasional shifts as she “will be spending more time in [her] second home state, Alaska.”
Winthrow joined the staff a year and a half ago as an emergency room veterinarian and served as the clinic’s medical director before becoming the owner, officials said.
Animal ER of Northwest Houston is open 24/7 to offer diagnostic services as well as emergency care and management for pets. The privately owned veterinary emergency practice received the Cy-Fair Houston Chamber of Commerce’s Small Business of the Year award for 2023.
