Wallenstein's email: 

Dear Friends & Colleagues:

I want to let you all know that after 4 years working for Congressman
Ackerman, today is my last day.

I am moving on to work for Governor Eliot Spitzer, where I will be
doing Intergovernmental Affairs and Jewish Community Affairs.

After today, you can feel free to reach me by cell phone at
917-###-### or at ross.####@####.com.

I will send out my new contact information when I get it.
