professional bio
Donald Barthel graduated from University of Michigan, Ann Arbor, with honors in 1986. He received his Juris Doctorate from U.C.L.A. in 1990, and immediately thereafter was admitted to the State Bar of California.
Mr. Barthel’s entire legal career has been dedicated to the defense of employers’ rights in the arenas of labor law, employment law, and workers’ compensation. For over three decades his practice has exclusively focused on workers’ compensation defense. With many years’ experience in southern, central and northern California, he has appeared at virtually every WCAB district office in the state.
Mr. Barthel is an acknowledged expert regarding the American Medical Association Guides to the Evaluation of Permanent Impairment and was a Reviewer for the Sixth Edition. A prolific and popular public speaker, he has taught thousands of adjusters, human resource directors, employer representatives, attorneys and physicians throughout California and the United States. Topics covered include just about everything ever addressed in workers’ compensation. He has also authored and co-authored innumerable articles focusing on workers’ compensation related matters.
A hopeless University of Michigan Wolverine fan, Don watches and roots for his football team at every opportunity. Any visitor to Don’s office will invariably be FORCED to view his many University of Michigan “collectibles” (known by most rational folks as “dust collectors”). Don revels in every Wolvervine win (and sulks — occasionally — over Wolverine losses) in the company of his beautiful wife, Tamara, and five wonderful children: Desmond, Emma, Benjamin, Tyler and Mimi and his beautiful granddaughters, Aaliyah and Jasmine.
