I have over 40 years of automotive experience, with 33 of those leading dealerships to success. In 2020, Ernie joined the Giambalvo organization as the General Manager of Giambalvo Hyundai of Hanover, after 31 years with the Hanover Automotive group. 

Ernie attended the University of Michigan with a focus on business administration and accounting. He then accepted a position managing the 9th largest Motorcycle dealership in the US for nearly 5 years before moving into the Automotive industry, where he has been ever since.

Ernie has lived in the Hanover Area for over 30 years, and is deeply involved in the community. He currently is the technical advisor to several Churches, helping to guide their efforts in music and visual production. In addition, he has assisted with the Halloween Parade, Hanover Easter egg hunts, car shows,  Make-A-Wish, Operation Claus and a wide variety of other community projects.

In his spare time you will find him either DJ'ing a reception or party, or riding his motorcycle somewhere fun.

Tom Couch
Vice President 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!
