John Mannebach III is a newly licensed attorney and recent graduate of the University of Oregon, School of Law. While attending law school, John served as an Executive Editor at the Oregon Law Review. He is an honors recipient for his pro bono service, and he obtained a certificate of leadership through the Frohnmeyer Leadership Program. John clerked with the Oldham Law Office before becoming an associate attorney; he has helped unions, nurses, firefighters, and others in on-going litigation. His legal experience also includes a clerkship with Access the Law—a modest-means civil litigation firm—helping clients fight eviction proceedings, drafting and executing wills for veterans, and advocating for local eviction-protection ordinances.


Prior to joining the legal profession, John had considerable experience in corporate finance.  As a financial analyst for a Fortune-200 company, John successfully delivered a comprehensive, multimillion-dollar global consolidation ledger while stationed in London, England. He has created annual corporate budgets, managed corporate capital reporting, and designed expense reporting for a business unit generating over $1B in annual revenue. As a financial analyst for a healthcare-consulting firm, John has modeled, reported, and presented specific revenue, expense, and profitability categories to support management decision-making. This experience dovetails with John’s practice in employment and labor law as John can recognize and implement successful and sustainable best-management practices, understands compliance issues, can easily sift through complex financial data from public and private employers, and recognizes the innate value and integrity of workers.


Outside of work, John is active in nonprofit organizations—especially those charities that provide housing-related services to the underprivileged—and his parish.  He also enjoys skiing in the Cascades, biking around town, and sharing laughs with friends and family.
