Decision pattern

Over your 10 years on the bench, Judge Sullivan has demonstrated a clear upward trend in approval rates. After starting with rates in the mid-60% range, your decision-making pattern shifted significantly starting in 2020, climbing steadily to reach a 91% approval rate in 2025. This recent performance represents a continuation of a long-term trend toward higher allowance rates compared to your earlier career. This pattern suggests a consistent approach to evaluating evidence and medical documentation.

Preparing for an SSDI hearing

The guidance below applies to any SSDI hearing, not specifically to Judge Sullivan's bench. Judge-specific preparation guidance requires a corpus of public Appeals Council decisions involving each judge, which we haven't built yet.

  • Bring a clean treating-physician record. Longitudinal primary-care or specialist notes spanning the disability period, with consistent symptom documentation, are typically the strongest evidence at hearing. A single month's records usually aren't enough.
  • Don't rely on consultative exams alone. If your medical evidence is built primarily around a one-time CE finding, expect detailed questioning. Supplement with treating-source statements where possible.
  • Prepare for daily-activity questions. Have honest, specific answers about a typical day. Answers that conflict with the medical record (in either direction) tend to hurt credibility.
  • Expect transferable-skills probing. A vocational expert will usually testify about jobs available to someone with your limitations. Your representative should be prepared to cross-examine.
