Local Allstate Agency: Meet Diamond Insurance Solutions, Inc.






























I’ve lived in the Matteson community for six years. I am a proud alumni of Illinois State University. Before coming to Allstate, I worked in corporate management and customer relationships within the insurance industry for fifteen years. I am passionate about educating and helping customers understand different aspects of insurance.
Being involved in our community is very important to me. As a result, I work on weekends as support staff at Mercy Home for Boys & Girls in Chicago. I believe in reaching out to the youth in order to help them build the confidence and skills they need to have successful futures. I am also a member of the Matteson area Chamber of Commerce, Chamber 57. I am a proud member of Kappa Alpha Psi Fraternity, Inc., currently serving on the Board of Directors for the Richton Park Kappa Alpha Alumni Chapter, in addition to serving as the Undergraduate Chapter Mendo for the Kappa Alpha Chapter (Illinois State University).
At the Diamond Insurance Solutions Agency, we believe that life is much more meaningful & fulfilling when one is able to impact the lives of others in a positive & unforgettable way.
You are valuable to us, & your relationship is precious. You are not just a number; therefore, we treat you with the ultimate level of care, respect, compassion, & service.
Your problem is our problem. We help provide simple solutions to sometimes complex protection issues. We aid your restoration after the unexpected. We help you protect what matters to your life: cars, property, assets, & most importantly....your family.
