Matty M. Sandoval earned his Juris Doctorate from the University of San Diego School of Law in 1987 after studying law in Salzburg, Austria and Florence, Italy, and has since represented over 8,500 Social Security Disability and SSI claimants in bilingual English and Spanish proceedings. Residual Functional Capacity opinions from treating orthopedic specialists such as Dr. Christopher T. Behr, MD anchor the medical record development that Administrative Law Judges weigh under the Social Security five-step sequential evaluation. Representation spans Initial application, Reconsideration, ALJ Hearing, and Appeals Council stages, plus direct federal court review in the U.S. District Court for the Southern District of California and the Ninth Circuit Court of Appeals. Longitudinal primary care documentation from physicians including Barbara Denysiak, MD supplies the continuous treatment histories that SSA requires for 12-month duration and severity findings. In-house paralegal support with Mexican attorney credentials handles Spanish-language case intake, medical record retrieval, and hearing preparation for monolingual Spanish-speaking claimants. The most demanding cases the office pursues are claims remanded from federal court for de novo hearings after more than 500 prior district court suits filed by Sandoval established a Ninth Circuit track record on credibility and medical opinion weight standards.
