Tom Couch
VP Of Operations

I started my automotive career as a sales person in 1985 after graduating from Penn State University. I realized how much I enjoyed this industry and decided to make it a career. My experience includes managing 19 different brands of foreign and domestic automobiles between 3 different dealer groups. My family consists of my son, Matt, my daughter, Rachel and my wife Dyna. Matt graduated from the United States Naval Academy in May of 2013 and was a member of their football team. He is currently on active duty in the United States Navy. My daughter, Rachel, completed medical school at Liberty University and was a member of their field hockey team. She is now a family physician at Carolina Health Specialists in Myrtle Beach, SC. My wife Dyna is from Union, West Virginia and graduated from Shepherd University in Hagerstown MD. In my freetime, you can find me on the sidelines coaching football at East Pennsboro High School in Enola. I had the great privilege to play football for Joe Paterno at Penn State and being on the 1982 National Championship team. And I'm now a proud grandparent of two young boys!

James Kotelnicki
Genesis Experience Manager

Originally I worked in the restaurant industry where I honed my skills with patrons and sharpened my customer service skills. Upon starting at Jack Giambalvo, I worked in the Business Development Center which became a great foundation for me to move into my current sales position. Helping customers to decide on a vehicle whether used or new is rewarding and enjoyable on a daily basis for me. I look forward to working with you as well and providing you the best car buying experience!

Jayme Cabott
Business Manager

I've been with Jack Giambalvo Hyundai Mazda for nearly 10 years. I've always enjoyed discussing cars as it's truly been a hobby of mine since a young age. Personally having owned over 40 vehicles thus far, I've gained vast experience with many makes/models to more accurately answer real world driving questions. I genuinely enjoy my job all while giving customers a fun, low pressure approach while considering their next vehicle. In my spare time I enjoy riding motorcycles, watching football, and trips to our beach house in Fenwick Island, DE with my girlfriend.
