Special needs: Friendship Circle, Yedei Chesed. (Dunno if Hamaspik uses volunteers…)
Hospitals: Chesed 24/7, Bikur Cholim
or maybe Good Sam could use volunteers, dunno
Nursing homes/rehab: Northern Metropolitan, Friedwald, Fountainview (dunno how volunteering works here either…)
Kiruv: Oorah ChillZone during the school year, JEP, babysitting at Ohr Somayach (dunno if that’s kiruv but they tend to need people)
Chai Lifeline (contact them for people in need in Monsey)
These are just things that friends of mine have done. (If you’re not a [teenage] girl some of them may or may not be open to you.) I’m sure there are many, many, more, especially if you look at your friends and family and see what voids you can fill (which is how I found my high school chessed job, which is NOT on this list). The opportunities are endless.
If you are looking for ideas, if you know any Monsey high school chessed coordinators…
