Firm Details

Devlin Law, P.C. continues the tradition of Rosenthal Greene & Devlin, P.C., one of the most honored and successful small law firms in Oregon for more than three decades.

John Devlin is the primary attorney at Devlin Law, P.C.  He worked with Elden Rosenthal and Mike Greene for a decade before taking over the firm in 2016.  Elden Rosenthal remains Of Counsel to the firm.  Mike Greene has moved to the firm of Folawn Alterman & Richardson LLP.

Devlin Law, P.C. primarily handles cases where a government agency or a corporation needs to be held accountable for violating an individual’s constitutional rights.  The firm believes that a jury trial, conducted in full public view, is one of the best ways to hold those institutions accountable.  In recent years, the firm has represented children abused by their foster parents, individuals arrested for crimes they did not commit, victims of racist violence, and jail inmates denied basic medical care.

John graduated Haverford College, Magna Cum Laude, in 1993, and from the University of Chicago Law School, with Honors, in 1998.  While at the University of Chicago, he was a member of the University of Chicago Law Review and wrote a note for the University of Chicago Legal Forum entitled “Genetics and Justice: An Indigent Defendant’s Right to DNA Expert Assistance.”  After graduation, John served for one year as a law clerk for Judge Ed Carnes, a federal appeals court judge in Montgomery, Alabama, and then for another year as law clerk for Judge Shira Scheindlin, a federal trial judge in New York City.

After completing his clerkships, John worked for several years as an associate at Shea & Gardner (now Goodwin Procter), a commercial litigation firm in Washington, D.C.  John moved to Oregon in the summer of 2004 and began working as a Deputy District Attorney in Multnomah County in January 2005.  During his time as a Deputy D.A., John worked in the misdemeanor trial unit and felony property unit.  While in the D.A.’s office John tried approximately 50 cases, as well as presenting cases to the grand jury.  John also spent eight months as the “DUII Deputy” and was responsible for issuing misdemeanor traffic charges and overseeing the DUII diversion docket.

John joined Rosenthal & Greene, P.C. as an associate in October 2006.  He became a partner in Rosenthal Greene & Devlin, P.C. in September 2010.  He took over management of the firm in 2016.  Over the last decade, he has handled personal injury cases ranging from automobile crashes and premises liability to medical and legal malpractice.  He has a particular interest in handling civil rights cases.
