If Chrysler would decide to put in a diesel it would be perfect". When Rodney is not at the dealership he enjoys traveling with his wife, Diane. He is an avid scuba diver, back packer and loves to work in his yard. He also enjoys mountain biking, kayaking and physical fitness. (Just ask him about P90X) He has passion for giving back to the community by doing volunteer work at the Lehigh Gap Nature Center and other various organizations.

He also does a lot of work with people who are trying to recover from the disease of addiction. Another thing to know is that he his a die-hard Philadelphia Flyers fan and a hockey nut! Rodney has also been an Eagle Scout since he was 15. He enjoys what he is doing both in his professional and personal life. His goal for the customer is to "Treat them as more than a customer, I want to help them to make an informed and intelligent choice in their automotive purchase."
