The TellerScore is our own summary of the figures this institution reports publicly; it is not issued or endorsed by any government agency. It is not a prediction, and deposits within insurance limits are protected either way.

From Q2 2025 to Q2 2026, the score rose 4 points (63 → 67), mostly because the earnings component improved by 7 points.

Percentile against credit unions of similar size nationwide (100th = best among peers; for ratios where lower is better, the scale is flipped).
