I'm glad you are interested in getting involved with the community. I wish there were much more people who would.
You choice of organizations though, is amusing. Why do you think that volunteering for that organization is the right match for you? It's hard to believe that the name of an organization alone would serve to draw out volunteers.
The Hackensack Taxpayer's Association has contributed nothing of value to the City of Hackensack and is working on no initiatives for the betterment of it's residents. They are a bunch of political wanna-bees and professional complainers. They are at war with the Mayor & Council on every single issue, in fact you can always know the position of the Hackensack Taxpayer's Association because it is always the opposite of the city administration. Please, don't waste you time with them.
If you would like to get involved with the community, here's a couple of suggestions for volunteering: (1) the Hackensack Riverkeeper organization (2) Hackensack University Medical Center, or (3) contact city hall and ask for Charlotte Paney (4) contact the Bergen County Volunteers Organization at the First Presbyterian Church.
Even volunteering at one of the city's homeless shelters would be preferrable to the Hackensack Taxpayers Association.
