About Dianna
Dianna Cannon built a legal career around a simple idea: the law can make a real difference in people’s lives. She speaks plainly. She listens more. That approach has guided her work for decades.
She attended The University of Utah S.J. Quinney College of Law beginning in 1989 and earned her J.D. in 1992. Her legal education came at a time of change in administrative law and disability benefits programs, and those areas would shape the work she took on after graduation. Since completing law school she has practiced across state lines, holding licenses in Utah, Nevada and California.
Early in her career Cannon concentrated on the procedural and evidentiary challenges facing people seeking disability benefits. Over time those case types became the core of her practice. She has maintained professional memberships dating back to 1992 and added additional association involvement beginning in 2017, reflecting steady engagement with the legal community and ongoing professional development.
Cannon’s day-to-day work involves advising clients about eligibility, handling filings, and representing individuals at administrative hearings. Her files commonly include initial benefit applications, reconsiderations, and appeals before administrative bodies. She spends substantial time preparing medical records, coordinating with treating providers, and presenting testimony before hearing officers. The work requires attention to detail and an ability to explain complex medical and legal matters to judges and juries alike.
She practices through Cannon Disability Law. The firm operates from multiple offices and serves clients in the jurisdictions where she is licensed. The practice handles matters at different stages of the disability process, from early denials through the appeals pipeline. Colleagues describe her as steady in hearings and thorough in file preparation; clients seek her out for direct counsel on practical next steps in often stressful circumstances.
Cannon has kept a steady professional rhythm over the years. She balances paperwork-heavy litigation with courtroom time. That balance informs how she staffs cases and manages client expectations. Outside of casework she pays close attention to evolving rules and administrative guidance that affect benefit determinations.
As of 2026 she continues to serve clients through Cannon Disability Law, representing individuals in disability claims, administrative hearings and appeals.
