Harrison Hull & Mumm represents insurance carriers, their insureds, and self-insured entities across Texas — from motor-vehicle and commercial trucking defense to coverage opinions, fraud investigations, and municipal liability.
We keep the roster focused so every file gets a senior hand. Carriers retain us because the lawyer assigned to the case is the lawyer who tries it.
Since 1993, Harrison Hull & Mumm has been defense counsel to national and regional insurance carriers and their insureds throughout Texas, Oklahoma, and New Mexico. The work is deliberate — coverage analysis first, defensible strategy second, trial readiness throughout. We don't churn files, and we don't pad bills.
Our attorneys try cases. That's not marketing — it's how we're staffed and how we prepare. When settlement is the right outcome, we earn it from a position of credible trial readiness, not from avoidance.
