William M. Janssen joined the Charleston School of Law faculty in 2006 after a
lengthy practice with the mid-Atlantic law firm of Saul Ewing LLP, where he was a
litigation partner, a member of the firm’s seven-person governing executive committee,
and chair of the interdisciplinary Life Sciences Practice Group. He concentrated his
practice in pharmaceutical, medical device, and mass torts defense and risk containment.
In practice, he was involved in several high-profile drug and device cases, including the
national diet drug (“fen-phen”) litigations, DES litigations, and myelographic contrast
dye litigations. He has spoken and written extensively on pharmaceutical and medical
device law. 

Professor Janssen also focuses his scholarship on federal practice and procedure. He is
the author of four national texts in this discipline. He is the sole author of Federal
Civil Procedure Logic Maps (West 2d ed. 2012), a visual learning resource for federal
civil procedure. He is one of three co-authors of the Federal Civil Rules Handbook (West,
annually (21st ed. 2013)), and A Student’s Guide to the Federal Rules of Civil Procedure
(West, annually (16th ed. 2013)). The content of the Handbook is reprinted each year as
Volume 12B of the national treatise, Wright & Miller’s Federal Practice and Procedure
(West). In addition, Professor Janssen is the author of various journal articles, book
chapters, and bar review materials on federal civil procedure, and has lectured widely on
civil procedure topics. 

Professor Janssen’s scholarship also includes an emphasis on constitutional religious
liberty and the Religion Clauses to the United States Constitution, an area of law on
which he has written, spoken, and litigated. 

He is also one of several co-authors of the annual updating to Rice’s Attorney-Client
Privilege in the United States, a leading treatise on the privilege. 

While a student at the American University’s Washington College of Law, Professor Janssen
was the executive editor of the American University Law Review, a dean’s fellow, a moot
court board member, an interschool moot court competitor, and the first-year moot court
champion. After law school, he served as a law clerk to a federal district court judge
(Hon. James McGirr Kelly, E.D. Pa.) and to a federal court of appeals judge (Hon. Joseph
F. Weis, Jr., 3d Cir.). 

Before joining the Charleston School of Law faculty, Professor Janssen taught as an
adjunct instructor at Temple University School of Law for five academic terms and as an
adjunct teaching business law at Saint Joseph’s University.
