Tire Forensic and Training Expert

TJ Tennent takes tires seriously. "While working for the world's largest tire and rubber company - knew that the knowledge of all things tires would be important. However, I never imagined how it could be useful or helpful outside of the job.

Now...three years into Tennent, Winkelman & Associates, I see how important this information is and can be - especially when there is an injury or death.

At the same time, seeing the results that comes from using "Tire Experts" (those that profess to have the requisite knowledge or just enough knowledge to provide incorrect advise or out right lie. It is tragic seeing the harm that can come from choosing a tire expert hastily."

At Tennent, Winkelman & Associates ethical standards mean everything to us. Our associates keep ethics in mind during the work understanding how important it is to have individuals that represent our clients to ensure the best possible results.
