  • Senior Citizens
  • Library


seniorThere are many and varied services available to Senior Citizens in Mountainside.

Most of the programs are county or statewide and not limited to Mountainside residents. In New Jersey, every county has an office on Aging.

These agencies supply information and referral services within their county. Additional information is available from Senior Citizen Coordinator, Kim Moriak at (908) 232-4406.

We have a lot to offer and hope you'll take time to explore our collection. In addition to our online catalog and array of electronic databases, we have a terrific photo gallery that chronicles the last several years of library history. And many people find our schedule of programs and activities a real convenience.
