    Hello York County friends and neighbors!  I have had the pleasure of assisting countless clients with their vehicle needs here at Thornton Automotive Manchester.  I have been employed here since January of 2007.  I take much pride in the many satisfied new and returning customers I've helped, as well as all of the clients I have met through customer referrals over the years.

     I started my career on the sales floor, but have taken advantage of every chance I had to learn the ins and outs of the automobile sales business.  This has included purchasing/selling vehicles at auction, participating in sales training, and attending national training classes.  A few years into my career, the Thornton Administrative Team recognized the aptitude that I had for the managing side of our business and I have since procured the role of Sales Manager.  I have always been a firm believer in posturing the best customer service for each and every client I meet.

     In my spare time, I enjoy being with my lovely wife and our two young children. Come visit me today and let me help you with all of your automotive needs!

    I started at Thornton Automotive Manchester in January 2013.  Prior to that I was a sales rep. at our sister company Thornton Chevrolet.

    I met Jeff Hotham when I joined the wonderful organization in April of 2012.  As a sales person for Chevrolet and my background as a certified auto technician for 5 years, I decided I would be fit for pre-owned sales. 

    I am completely devoted to helping you find the perfect vehicle and making sure you're completely satisfied with your purchase.  If you're in the market for a pre-owned vehicle, please come see me today!!!!
