Seth Geller
Plastics Machinery Sales Manager
I joined Machinery Network in 1995 and have been managing their plastics machinery division ever since. I am originally from Long Island NY ,home of the two greatest sports teams the NY Yankees an NY Rangers. My goal in this business has always been to make customers feel so comfortable with me that you can deal with me over the phone without ever meeting me and still have the confidence to make a large used machinery purchase knowing that you are in good hands and will be provided with a great deal and superior service. When I am not making customers amazing deals on machines I am home yelling at my TV when Hockey or Football is on or out playing Hockey or other athletic activities.
