Our agent explained coverage options clearly and found a better bundle than our previous carrier. Claims follow-up was prompt when we had a minor auto incident.

We moved from out of state and needed new auto and home policies quickly. They walked us through local requirements and wind deductibles without pressure.

Compared three carriers for homeowners and auto. Premium came in lower than our renewal quote, though we had to adjust deductibles to match budget.

Staff returned calls same day and sent policy documents electronically. Would recommend for anyone shopping independent agents in the area.

They reviewed our policies at renewal and suggested umbrella coverage we had overlooked. No hard sell — just practical advice.
