William Cantu: Allstate Insurance

You can view my financial industry experience and background at FINRA’s BrokerCheck

Local Allstate Insurance Agent: William Cantu

I have lived in San Antonio my whole life with the exception of my college years. I graduated from Edgewood High School here in San Antonio. I then attended and graduated from The University of North Texas in Denton. I take pride in hearing visitors say that San Antonio is such a friendly city.

God blessed my wife and me with three boys and one girl. While they were growing up, we enjoyed taking them to some of our favorite local spots like the downtown river walk, the Alamo, the San Antonio Zoo and Witte Museum. Now, we're starting the cycle again with our grandchildren.

I've had the pleasure of volunteering with numerous community organizations like the Boy Scouts of America, Bexar County Juvenile Justice Academy, The Madonna Neighborhood Center, the Tejano Music Awards, Texas Probation Association, Texas Buffalo Soldier Organization, YMCA, Spurs Youth Basketball League, Texas Corrections Association and the Southside Cardinals football.

I opened my office on September 1, 2016. The five words I feel best describe my agency: knowledgeable, caring, diligent, enthusiastic and trustworthy. Stop by the office soon--I would love to meet you and discuss your insurance needs!

Products we offer:

Car Insurance Agent in San Antonio
Car Insurance Agent in San Antonio
Helps protect you and your vehicle if you’re involved in a car accident. At a minimum, you’ll likely need bodily injury liability and property damage liability to meet state auto insurance coverage requirements and help protect your finances if you cause an accident that injures another driver or damages their property. We also offer uninsured motorist coverage to help with your expenses if you’re hit by a driver without insurance. If you’re looking for coverage to help protect your vehicle, you might want to consider collision coverage and comprehensive coverage, which help pay repair costs if your car is damaged in a covered loss. And, optional coverages, like new car replacement coverage or loan/lease gap coverage help protect your investment in a brand-new car. I can help you choose a combination of coverages that fulfill state requirements and meet your needs. Give me a call to get a car insurance quote today!
