Driven By Our Core Values
Do The Right Thing.
Integrity is not about convenience. It’s an unwavering commitment to do the right thing in every action we take and in every decision we make, even when no one’s looking. Make decisions that build strong, trusting relationships.
Make quality personal.
At Wentworth Automotive, we do not do good, we do great. Take pride in the quality of everything you touch and everything you do. From the way you perform an inspection to the final touches before delivering the vehicle to the customer, from the smallest service to the three-day engine job, always ask yourself, “Is this my best work?”. Remember that absolutely everything “speaks” to our customers, and everything you touch has your signature. Customer’s vehicles are driving billboards that advertise our commitment to quality and how much we care.
Be Performance Driven.
We appreciate effort, but we reward and celebrate results. Set challenging goals, and then go after them. Don’t shy away from metrics or accountability. Numbers are the best tools we have in order to help us understand how we’re doing and how we can improve our performance. Holding ourselves accountable for results reflects on our commitment to our mission.
Be a Superstar!
Be willing to do whatever it takes to accomplish the job…. plus a little bit more. Whether it’s starting early, staying late, or doing something that’s not in your job description, it’s the extra mile that separates the average person from the superstar. Be a superstar!
Continuous Improvement.
Constantly evaluate and reevaluate every aspect of your job. Don’t be satisfied with the status quo. The most successful people and organizations are in a never-ending pursuit of improvement.
Appearance Counts.
Your personal appearance makes a strong statement about the pride you take in your performance. Keep your uniform neat and clean. The appearance of our shop makes a similar statement about the quality of our work. Take responsibility to ensure that everything the client sees is clean, neat, and professional. It is not someone else’s job. It is everyone’s job. Remember Everything Speaks.
Embrace Innovation.
Nothing stays the same. Innovation creates energy and excitement. Our ability to innovate and change will set us apart from others in our industry. The more innovative we are will make us a stronger and more successful company.
Take Ownership.
No excuses, stories, or justifications. Take 100% responsibility for your successes, failures, what you do, and what you do not do (could have, should have). Everything speaks and taking responsibility for our actions and outcomes shows a commitment to excellence.
Set & Ask for Clear Expectations.
We judge situations not by what happens, but by how they compare to what we expected to happen. Nearly every misunderstanding can be traced to a difference in expectations. Learn to create mutually understood expectations in every situation.
