Corinne A. Militello rejoined Ballard Spahr as counsel in Philadelphia, chairman Mark Stewart announced Monday, after serving as an assistant privacy officer for Penn Medicine at the University of Pennsylvania for two years. Militello said she wanted to rejoin Ballard because it gave her the opportunity to combine her abilities in intellectual property and data security.

Militello oversaw Health Insurance Portability and Accountability Act compliance for Penn Medicine, which has five hospitals, more than 200 physician practices and a medical school research program. Her work included handling the patient privacy complaint process and issues involving privacy of electronic health records.

"Her two years at our client Penn Medicine will give her excellent insight ... into the specific types of challenges they face," said Lynn E. Rzonca, who leads Ballard's trademarks and copyrights practice group.

Militello, whose first day back at Ballard Spahr was Sept. 7, was an associate at the firm from 2007 to 2014. During that time she counseled clients on preparing privacy policies and dealt with consumer privacy investigations. As she returns to the law firm, she said, she brings with her "exposure to evolving privacy trends and issues in the complex health care sector."

Rzonca said Militello will return to counseling clients on intellectual property issues including product development and enforcement, but will combine that work with data privacy and security as well as some health care data matters.
