    My father was a Chevrolet dealer in Duluth, Minnesota for 23 years. His business afforded me a great start in the industry.In 1968 I began in the Parts Department at age 13, then advanced to car detail and light maintenance on the preowned lot.  


    My sales career began in 1975 as a favor to a former high school Business Policy teacher.  Uncomfortable with the sales process, he asked if I would help him buy a new Caprice wagon. Most of my teachers and coaches had traded with my family's dealership but I had never personally handled a sales transaction from start to finish. I got the bug; throughout my final two years of college, I sold full-time, working afternoons and evenings.


    By 1981 I became the General Manager when my father semi retired and began residing in Florida for six months each year.  Two years late my father was diagnosed with cancer and we decided to sell the dealership. I stayed on as new car manager for the new dealer, Rathert Chevrolet, until July 1985.


    In August I sold my house and moved to North San Diego County. The first three months I struggled at a high turnover, fast track store. I was close to deciding the car business was not for me, but stayed to wholesale cars and learn the retail reputations of dealers countrywide.


    In early 1986 I returned to retail, selling Oldsmobiles and Audis for Hoehn Motors in Carlsbad, California.  Within six months I was promoted to sales manager; six months later, I was promoted to Hoehn Mercedes Porsche Sales Manager, a very coveted position. At 32, I was both the manager and the youngest member of the sales department?and scared to death. The position had always been held by a Hoehn family member.


    Hoehn's acquired an Acura franchise in 1989 and  I was asked to open it, hire new staff, and I become the general sales manager. I later moved to Hoehn's Mercedes store. While working for Hoehn, I met my wife Connie, an Oklahoma native.  It was Connie who introduced me to my present business partner, Jack Cooper. 


    Connie and I were married in June 1991.  In August, Connie and I, accompanied by my 15-year-old stepdaughter moved to Tulsa. On August 15, 1991,Jack Cooper and I closed on the purchase of a dealership in Tulsa and immediately began doing business as Jackie Cooper Imports of Tulsa, Ltd. We sold and serviced Mercedes-Benz, Volvo and Nissan with a staff of 23 employees.  We've grown A LOT since then!


    My goal was to be a dealer by age 35.  I missed it by one day; I turned 36 on August 14, 1991 but was no less happy with the accomplishment!

    918.362.1222

    I have been with Jackie Cooper since 2003.  I started out my career in the banking business where I did auto loans for dealerships.  In 2001 I was offered a job at a dealership where I assisted clients with their financial needs.  Eventually I transferred over to the Internet as I saw it as a new and growing opportunity.  I am Certified with all our manufactures and take continued classes in the new and upcoming Internet technologies.  In 2008 we had the opportunity to add smart as one of our new franchises and I took over as the brand Manager.  It is a safe and fun vehicle and I am very excited to be apart of it.

    In my spare time I enjoy spending time with my three terrific kids.  I also enjoy painting and outdoor activities.  Being a Pisces if I am around water that is surely where you will find me!  I enjoy scuba, snorkeling and fishing!
