Jonathan Corey

Jonathan has practiced law in Oregon since 2004. In that time, he has been mentored by several of the best Family Law attorneys and litigators in the state. As a result, he delivers a high level of experience, savvy and wisdom to each of his clients.  In 2014, he was recognized as a “Top 10 under 40” by the National Academy of Family Law Attorneys.  In 2015, he was named part of the “Nation’s Top One Percent” by the National Association of Distinguished Counsel.

Jonathan’s client-focused approach drives him to find the right balance between strong advocacy, effective representation, and overall guidance on the transition that takes place during a family law matter.  Jonathan believes that every client’s needs are different; he strives to determine those needs and meet them in the most-efficient way possible.

In addition to his client-focused approach, Jonathan also enjoys serving his community and charitable causes.  He is most proud of his pro bono representation of children in high-conflict custody proceedings – where Multnomah County Judges rely on Jonathan’s input to help resolve parental conflicts that are often injurious to innocent children.  “Representing children in high-conflict cases makes you understand the real impact that a family law proceeding has on the many lives it touches.  It’s a great service to the community and also a source of wisdom that I pass on to my adult clients throughout their case.”

Also, as chairman of the Multnomah Bar Association’s Golf Committee, Jonathan is instrumental in raising thousands of dollars every year for the Volunteer Lawyer’s Project – a program designed to provide critical legal services for low-income people. Jonathan also volunteers for the Portland chapter of Guide Dogs for the Blind and loves raising his rescue dog.

When he is not hard at work, Jonathan enjoys playing in a Portland Basketball league to keep his mind sharp. An avid sports fan, Jonathan will freely admit that he is happiest during football season.
