About Us

Petri Insurance was established in 1921 by John L. Petri. In 1969 Armin J. Glessner took over. Upon his death in 1975, John Glessner and his mother continued the family’s fine tradition of service to their customers. Today, John is joined by Brett Wiegand a lifelong resident of Waterloo.


Why an Independent Insurance Agent?


Some people think it doesn’t really matter where they buy their insurance, but this misconception could be costing them money, service and protection.Buying insurance isn’t like buying bread or milk. Insurance is an important safety net for your family, your home, your car or your business, Don’t treat the purchase lightly! There is a difference in where you buy your protection.


What are the three sources for insurance?


1. Captive Agents – Can sell you the insurance of only one company.
2. Telephone Representatives – Can offer you the insurance of one company, and only on the telephone.
3. Independent Insurance Agents –  Like Petri Insurance Agency who represent many insurance companies, research with these firms to find you the best combination of price, coverage, and service.

Your Independent Insurance Agent…

●  Is a licensed professional with strong customer and community ties.
●  Gives you excellent service and competitive prices because your agent can access the insurance coverage from more than one company.

How we serve you is as important as what we provide. First, we listen to you… we discuss your needs and answer your questions. Next, we look at both your short-term and long-term objectives and help put your insurance and planning needs in perspective.
