Effy and Dina Weissmandl

Camp Operators


Effy and Dina Weissmandl have spent most of their adult lives working in the world of children’s summer camps.

It has always been their dream to have a camp of their own. In 1998 their dream came true and Camp Merockdim was born. Effy and Dina started Camp Merockdim in Ramapo College, NJ, then moved the camp to Monsey a few years later. Now, two decades later, Camp Merockdim has found its home at 175 West Clarkstown Rd. in New City and has become Champion Day Camp.


It is our passion to make a difference in the lives of every one of our campers. We are constantly working on our development as a place for children of all ages to belong and grow.

We look forward to meeting you and welcoming you into our camp family.
