Westerholm Koehler Insurance is an independent agency in Seguin, Texas. Founded in 1965. Family-owned since day one.

We write auto, home, business, life, supplemental health, farm and ranch, and umbrella coverage for households and small businesses across Guadalupe County and the surrounding Hill Country. We're not tied to one insurance company — we represent thirty-plus carriers and shop them side by side at every renewal.

That's the short version. The longer one includes founder Kermit Westerholm, the chain of ownership through to Kerry Koehler, and the slow accumulation of customers whose kids are now customers themselves. Read the full story →

What makes us different

Three things people keep telling us.

01

You answer the phone.

No phone tree, no 'your call is important to us.' A person picks up.

02

You know my file.

Six licensed agents and a long-tenured receptionist, more than 100 combined years at this agency. Low turnover means someone remembers what's on your policy and why.

03

You shop the market.

Captive agents quote one carrier. We quote thirty-plus, and we re-shop your policy every year — not just the day you sign up.

A multi-generation client
My family has been with WKI for a very long time. Now that my kids are grown and buying homes, they're using WKI too.

We work across Seguin, New Braunfels, McQueeney, Marion, Schertz, Cibolo, and the broader Guadalupe County / Hill Country area. Most of our clients live within a thirty-minute drive of the office. Some have been with us for decades and wouldn't trade their agent for a 1-800 number.

We help:

  • Households shopping auto, home, life, and umbrella
  • Trade contractors and small businesses
  • Ranches and rural property owners
  • People who want a real conversation, not a sales script
