General Manager

Matt Rock
General Sales Manager

I have been in the automotive industry since 1997. I started out in sales, where I sold a mix of brands for 6 years. From that point, I moved into management, beginning with finance. I found finance fit me perfectly. Having one on one interaction with customers was natural to me. It allowed me the opportunity to help families navigate their automotive needs pressure free. I met many good people and friends for life. After spending over a decade in finance, I decided to take the next step out of a desire to learn more. I am now the General Sales Manager here at Jim Ellis Kia. While the task is tall, I love the challenge. Being someone that enjoys participating in sports, I am extremely competitive and will never relent from being the best "ME" possible. I also hold my staff to those same standards. In turn, making the Jim Ellis motto of "Always expect the best" easy to achieve. We are looking forward to servicing your automotive needs now and for years to come. If you ever have any questions or just need automotive advice, please feel free to reach out to me personally.


Continued Blessings…

Alfredo Ospina
Product Specialist

Good day to you all; my name is Alfredo Ospina. I was born in Colombia and have been Stateside for over 33 years. I have a degree on Economics and an MBA. I worked for 21 years at a company in Fort Lauderdale as a GM and we worked along all the dealerships in the area doing warranty work, FOB parts, as well as aftermarket.

After that, I started working as a car salesman at a Kia Dealer in Florida. I find car sales a fascinating field, it gives me the opportunity to interact with people in all walks of life and always have the opportunity to learn something new and is an enriching experience.

By now, I have almost 7 years' experience with Kia and it has been an eye opener. I am absolutely convinced of the brand being the best value for your money; besides the fact that as a car manufacturer they have come a long way and they are, and have been for the last few years, on top of the list on quality and customer satisfaction.

Don't hesitate to contact me so I can show you that getting a car can be a fun and productive experience, let's get the old ways behind and let me guide you through the best experience you will have in the car business!!
