Trees Mobile Home Park Sunman, Indiana

I was wondering if anyone knew or know how I can find out who the owner is or a phone number for the owner of Trees Mobile Home Park Sunman, Indiana. All I know is that on the front sign it says the owner is MHP Investments. I have lived in this park for 20 years and since the new owners took over and a new manager was appointed I am having alot of troubles. The manger of the park will not give me the owners phone number. SO hopefully someone here could maybe help me.
