Ari. D. Halpern – Attorney

Ari grew up in Washington state and earned his undergraduate degree in psychology from UCSD in 1995. He graduated from Seattle University’s School of Law in 2003. His focus since law school has been on lawyering with a positive impact. He originally moved to Bend in 2004 and began working for Legal Aid Services of Oregon, primarily representing domestic violence victims. In 2007, Ari and his wife Lisa departed for a year-long, round-the-world trip. Upon their return, Ari began practicing Social Security Disability law at his father’s firm in Washington before moving back to Bend in 2010 to open a practice here. Since 2008, Ari’s sole practice area has been Social Security disability. He has represented many hundreds of clients in their disability claims. Ari & Lisa have 2 wonderful daughters and his family loves to travel and explore the great outdoors.

Jolene M. Simpson – Legal Assistant

Jolene has been working as a legal secretary/assistant for the better part of 30 years.  She brought the experience and knowledge she has gained over those years with her when she joined the Halpern Law Group team in 2016.  She enjoys working in the Social Security disability arena because she feels she is helping people who really need help, and she feels it is a positive, worthwhile use of her skills and talents.  When not working, she enjoys spending time with her husband and many grandchildren, working in her garden, cooking, serving in her church congregation, and occasionally helping women in labor as a birth doula.

Joyce A. Mumia – Legal Assistant

Joyce is originally from Kenya in East Africa. She graduated from Makerere University School of Law in 2007.  After graduating, she worked in Kenya for three years as a legal assistant at a telecom business.   In 2010 she moved to Seattle, WA with her family. She later moved to Redmond, OR and joined Halpern Law Group in July of 2018.

Joyce enjoys being a part of the HLG team in assisting clients in their SSA disability cases.  Joyce is passionate about helping others and finds motivation in knowing her positive contribution at work leads to bettering our clients’ lives. When she is not at work, she enjoys spending time with her daughter; going on road trips; hiking; and learning about different cultures and their cuisines. She is fluent in English and Swahili (her native language).
