Bio: My name is Doug Thompson; I am the President of Fixed Performance, Inc. Our company works with dealerships in the United States and Canada helping them to improve their Service, Parts, and Collision departments. We work with your team to implement the best practices for ensuring, customer enthusiasm and care, profitability, and employee satisfaction. Our program will provide training, encouragement, and motivation for your staff to achieve higher standards and enjoy more successes. We provide processes that work, structured accountability, training for managers and technicians, and support staff, all in an uplifting and encouraging fashion to ensure long-term success. The career path I have followed has allowed me a wide variety of experiences in the dealership environment. For 40 years I have had the opportunity to work in both fixed and variable operations as an employee, an equity partner in a dealer group and now as a consultant and trainer. Each task and experience in my career has helped me to learn and be able to help others as well. We define service as “Making Good Things Happen for Other People” working with your team to face the challenges, find the resolution and use each challenge as a learning experience. It is our goal and our desire to improve the quality of life for the dealer, the managers, and the employees. Working together to solve the puzzle is very rewarding and never-ending. In almost every case our processes implemented and maintained will provide a substantial increase in gross profit levels. In many stores, this improvement is in excess of $250,000 annually. In some cases that number is much greater nearing the $1M mark and in dealer groups the $1M is not uncommon.
