It looks like clients have been very happy with the service and results here. I requested a call back for that reason - good reviews. I got a call a few days later, answered a lot of questions, submitted everything they asked for and waited.... 2 weeks went by. I emailed and called and left a message. No reply. 30 days... same thing. At 45-ish days I emailed again asking them to please destroy my file (I gave them a lot of confidential info) if they were not interested in representing me in my disability case. NO REPLY TBH I've never even had this experience before so I admit I'm kinda shocked and disappointed.

A close family member has had an incredibly difficult time trying to get her disability benefits reinstated. She was originally found disabled in 2007 and received SSI and SSDI for years. Her benefits were terminated in 2019 because she didn't know she was required to report her income each month, which resulted in a $1,700 SSI overpayment. In 2022–2023 she tried to get her benefits reinstated and worked with Utah Legal Services. They were completely unhelpful. She kept them updated, they did nothing, and she ended up getting denied three separate times for "insufficient evidence." Each time, at least one medical provider failed to submit records, but no one ever told her what was missing or how to fix it. To make things more confusing, she also qualified under her mother's record as a Disabled Adult Child (DAC), which no one properly explained. When her mother retired, she started receiving auxiliary DAC retirement benefits in February 2025. She didn't even know this was happening until recently because SSA withheld 100% of the payments. She will not actually receive anything until late next year. The reason? SSA claims she owes thousands in Medicare premiums that continued to accrue for years after she lost SSI, even though she had no coverage during that time. She has dealt with a long line of dismissive, condescending people, from attorneys to SSA reps, who treat her like she's trying to "game the system." Very few people have helped her, and the delays have been devastating. She even lost her apartment during this process. She's been terrified to work, because working without understanding the rules before is what got her benefits terminated in the first place. When she spoke with Dianna, she was told things that were simply incorrect. Dianna insisted Medicare was free, dismissed the fact that SSA had been withholding everything, and immediately became impatient and rude. She told her, "I can't help you, you never worked, all you'll ever get is SSI," and re
