As a young boy I grew up like most of us did loving cars. I now have the ability to live out my childhood dream of being able to drive Porsche automobiles every day and even better I have the ability to help others fulfill their dreams as well.

After two decades I remain grateful for every client that takes time out of their busy schedules to come visit us and allow us the opportunity to assist with their automobile needs. We have been family owned and operated since 1964.

I started out in my automotive career washing the family car in my driveway. Since then I have always been fascinated by the complex engineering and craftsmanship it takes to produce each one. The Porsche brand has always been at the cutting edge of performance, engineering and style within the automotive industry. I cannot imagine a better or more exciting brand to sell.

I have been in love with Porsche since Jake Ryan drove his red 944 across the screen in Sixteen Candles.  It is an honor to now be working for such an iconic brand and family owned dealership.

It has been a pleasure to assist clients with high line automobile purchases for over two decades in Atlanta.  It is a dream come true to now be able to assist clients with the purchase of a Porsche.

Raised in the mountains of North Georgia, tradition and heritage run deep, especially with racing and automobiles. These principles are what sparked my interest in Porsche, and have made me a lifelong enthusiast. I remember the first day I laid eyes on a 911, the way the lines came together with sophistication and purpose, the way it looked like it was in motion standing still, I knew it was something special. Before I could even reach pedals, I knew that I wanted to dedicate my professional life to being a part of Porsche. My career with Porsche began with Gold Meister Certification and five years as a service technician. Moving to sales was a natural progression, as I now get to share my technical knowledge, brand history, and personal passion as I guide and educate clients, helping them to find their perfect Porsche. My work is a big part of my hobbies, where you can find me at Porsche and other Atlanta motorsports events. I also enjoy fine dining, travel, and shooting competitive firearms. My partners in all of this, and the ones that make it all worthwhile, are my wife Kimberly, and our rescue Maltipoo, Elee.

Porsche Certified Brand Ambassador

Utilizing my unique background with Porsche Cars North America, I am proud to call Hennessy Porsche home. My path to Hennessy started when I was born locally in Roswell, and I began racing at a very young age. Growing up, I would walk the Porsche lot, and dream about working with Porsche. It is a true honor to be a part of the Hennessy Porsche team, and see my dream come to life. In 2012, I was chosen for the Mazda Road to Indy shootout with a clear path into open wheel racing. My racing background created the opportunity to join the Porsche Experience Center Atlanta in 2014 as Lead Driving Instructor. This gave me the opportunity to showcase Porsche models to our customers in a dynamic, track focused environment. Within a year, I was chosen by Porsche Cars North America to be the Brand Training Manager. In this role, I successfully launched the entire Porsche model line-up to the North American market, training every dealership in the country on product knowledge and soft skills training.

In my personal life, I enjoy spending time with my family, and racing.

Welcome to Hennessy Porsche, Atlanta's Premier Dealership. Please feel free to reach out to me directly, and schedule your custom-tailored consultation. I sincerely look forward to speaking with you.

Porsche Certified Brand Ambassador

Cars have always played a significant role in my life; my earliest childhood memories revolve around my fascination with all things car related. So a career in the automotive industry was a natural path for me. 

Since beginning my automotive career in 2006, I've had the honor of delivering countless luxury, performance, and exotic vehicles to clients from all over the world. My goal with every one of my clients is to build a lasting relationship. I work to thoroughly understand their wants, needs, and expectations. Then I deliver to make sure my clients have a genuinely memorable experience. I establish loyalty through my commitment to providing outstanding customer service every step of the way. I have had the pleasure of guiding many through their very first car purchase. I've also been trusted to manage several collectors' automotive portfolios. Each transaction is unique, and I handle every one of them with the highest level of care.

As a true automotive enthusiast, and having personally owned several Porsche cars, I am thrilled to be a member of the Hennessy Porsche Family. While away from the dealership, I enjoy spending time with family, attending car shows, and trying out different restaurants around Atlanta.

I have seen Porsche introduce many milestone vehicles, from the 944 to the technical marvel of the 959. I've witnessed the launch of the Boxster and the first water-cooled 911 in 1998 as well as our four door Cayenne and Panamera. One high point for me was winning a trip to see Porsche compete at the Indy 500 in 1988. Having dinner with Al Holbert and Norbert Singer from Porsche Motorsport was an experience that I will never forget! All of these experiences have left me with an appreciation for the amazing vehicles Porsche creates. Looking back, I can say that the very best part of my 30+ years with Porsche was not the cars but the wonderful clients I have had the privilege to serve. Many have become my closest friends - my "Porsche Family!"

I have been in and around the Automotive industry, in some form or fashion, just as long as I can remember. Riding along with my father to the different dealer locations in the northeast where my uncles owned a handful of dealerships as a boy. As soon as I was able and had the opportunity to work on my own to find a niche in the auto industry I took the shot. After about 16 years on my own at various different brands in the auto industry, landing here at Hennessy Porsche North Atlanta aligns perfectly with what I am looking for right now. The automobiles, the enthusiastic atmosphere and the owner loyalty to the brand and the heritage excites me.
