Local Allstate Agent: Meet Diana Wickman

I’ve been working in the insurance industry for more than 40 years and have been an Allstate agent since 2009. As a Agent living in Garland for many years with my husband and two children, I’ve come to know many local families. The best part about being an Allstate agent is getting to know the customers and being able to confidently help them. I strive to find the best options, depending on customers’ needs and lifestyles.

I am a military wife of 32 years. I have two adult sons and one daughter-in-law. One of my sons is a physician in Louisiana and the other is studying to be an orthopedic surgeon. I enjoy being involved in my community as I used to volunteer as a girls’ basketball coach. I also sponsor events at Bishop Lynch High School and the local Jewish community. I like art, good food, gardening, sports such as golf and tennis, and other outdoor activities. I also love to travel.

Our team here in Richardson strive to always put the needs of the customer first. Most of my staff speak fluent Spanish, therefore allowing us to cater to a wider range of customers. We are here to answer your questions and with our understanding of the people in this community, we can help you protect the things that matter most–your family, home, car, and more. Please stop by our office at 1100 E Campbell Rd. in Suite 160. We look forward to meeting you.

Allstate Brings College Football Fans to Go All Hands In

We were excited to represent Allstate alongside the college football community to make good things happen with KaBOOM! by renovating Kids Square Park in Dallas. Throughout the season, with the help of college football legends, Allstate has gathered fans to volunteer at special community service projects ahead of some of the most highly anticipated matchups to show that when fans come together, good things happen. It was so fulfilling to go All Hands In with KaBOOM! and Oklahoma and Texas fans!
