A Real Agent. A Real Relationship.
Castellano Insurance Group was built on a simple belief: you deserve an agent who knows your name, understands your needs, and picks up the phone when you call.
Our Story
Estevan Castellano founded Castellano Insurance Group with one goal in mind: to give Texas families and businesses the kind of personal, honest insurance service that's hard to find in today's world of 1-800 numbers and automated systems.
As an independent agent, Estevan works with multiple top-rated carriers — which means he shops the market on your behalf, finds the best coverage at the best price, and explains everything in plain English. No jargon. No pressure. Just straight talk.
Whether you're insuring your first car, protecting your home, planning for your family's future, or covering your business — Castellano Insurance Group is here for the long haul.
When you call, you reach someone who knows your name — and your coverage.

What We Stand For
Personal Service
You work directly with Estevan — not a call center, not a chatbot. When you have a question or need to file a claim, you reach someone who knows your policy and your name.
Honest Advice
We don't sell you coverage you don't need. We take the time to understand your situation and recommend only what makes sense for your life and budget.
Independent & Unbiased
As an independent agency, we work for you — not an insurance company. We shop multiple carriers to find the best combination of coverage and price.
Long-Term Relationships
Insurance isn't a one-time transaction. We're here when your life changes — new home, new baby, new business — and we'll make sure your coverage keeps up.
