Approval rates
Comparing approval rates requires looking at data from the same timeframe. While your judge's 39% approval rate reflects her entire record since 2017, her latest-period performance shows a 37% approval rate, which sits 20 points below the Detroit office average of 57%. These figures are based on 2,807 decisions on record, providing a view of past activity. Aggregate rates describe past decisions, not predictions for your individual hearing.
Office- and national-level breakdowns of fully favorable vs denial rates aren't currently published by SSA in the per-office disposition data. The judge's own breakdown is the detail we have today.
Approval rate over time
Year-over-year approval rate across Judge Mamelka's docket. Annual rates fluctuate with the mix of cases SSA assigns; the longer-run pattern is more informative than any single year.
Decision pattern
Since January 2017, the approval rate for Colleen M. Mamelka has fluctuated, moving from 38% in 2017 to 55% in 2024 before settling at 37% in the partial year of 2026. This trend indicates that while your judge's decisions have varied over time, the latest period reflects a return toward her historical average. These shifts are common and may be influenced by changes in the complexity of cases or the quality of evidence presented.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Mamelka'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.
