Dianna Cannon

Dianna Cannon lawyer Salt Lake City UTDianna Cannon has been representing Social Security Disability claimant’s for 30 years. During that time, she has won thousands of disability claims. She has also won disability claims under the Black Lung Act, before the Railroad Retirement Board, and the Veteran’s Administration.

She is a sustaining member of the National Organization of Social Security Claimant’s Representatives. Ms. Cannon is a member of the Board of Trustees for the S. J. Quinney College of Law at the University of Utah. She is also an adjunct professor for the law school, where she teaches Disability Law. Recently, her colleagues voted for her inclusion in Utah’s Legal Elite in Utah Business Magazine. In 2019, Thomson Reuters published Dianna Cannon’s book, Social Security Disability Claims, Volumes 1 & 2. Her book is an attorney’s guide to practicing Social Security Disability law.


Ms. Cannon’s interest in disability law began during law school. At that time, she found few firms were representing individuals with disabilities. Even though disability is something that can happen to anyone, the government can make it difficult to obtain benefits.

In order to win benefits and fight government agencies like the SSA, individuals with disabilities need a lawyer. Most importantly, clients without a job need to be able to hire an attorney without coming up with a lot of money. Seeing an opportunity to provide legal help for those seeking disability benefits, she started Cannon Disability Law. Since then, her firm has won over $100 million in client’s past-due disability benefits.

As a past president of the Women Lawyers of Utah, she supports diversity. She also supports the advancement of women in the legal profession. Additionally, she encourages women and young lawyers to open their own law firms. Small, local firms can provide affordable legal services to everyone. Ms. Cannon has also been a board member of the ACLU of Utah. The ACLU works for freedom of religion, freedom of speech and of the press, and other civil liberties. Because Cannon Disability Law serves clients throughout the Intermountain West, Ms. Cannon is licensed to practice law in Utah, Nevada, California, and Washington state.


Over 20,000 people have won disability benefits through Cannon Disability Law. Cannon Disability Law’s firm headquarters is in Salt Lake City, Utah.  Ms. Cannon’s firm is known as one of the best disability firms in Salt Lake City, Utah and the Intermountain West. Additionally, her firm is listed as one of the best Social Security Disability firms in Las Vegas, Nevada.  The firm represents claimant’s throughout the western United States, including Utah, Nevada, California, Idaho, Washington, Colorado, Oregon, Arizona, and Washington.

Dianna Cannon has won thousands of disability cases at the hearing level. Additionally, she has won hundreds of cases at the Appeals Council.  She also has extensive experience in Federal Court. While winning disability benefits is the ultimate goal,  “helping people navigate Social Security’s system is the most important thing we do. Because we have been practicing disability law for 30 years, we are experts. Therefore, we understand medical issues, the law, and we know how to build a case. Likewise, we know how to obtain important evidence. This is where Cannon Disability Law excels. We work hard to collect all of our client’s important evidence. Also, our clients know we are on their side. We are behind them 100%, during what is the difficult process of winning benefits.”


Ms. Cannon has good advice for her clients. She states, “If you are looking for a disability attorney, make sure you hire an expert. Your future depends on hiring the right representative. If your disability prevents you from working, then you must have a monthly disability payment to live. Therefore, your future income is a stake. You don’t want to hire the wrong attorney. Especially when your future or children’s future is at stake.”

She goes on to say, “An important thing to look for when hiring an attorney is their past success rate. If they have a high success rate, then they have the experience to win your case. Experience is crucial in court. You want your attorney to know the judge. Because, the attorney should know the facts the judge is looking for to grant the case. A high success rate tells you the attorney gives their full effort to cases. At Cannon Disability, we win the majority of our cases. Not many firms have such a high win rate over thirty years. Our success rate speaks for itself.”
