I'm wondering if anyone knows of any non-profit, free clinics in the NH/Boston area that I can volunteer at. I am a licensed EMT and have all my CPR certifications, etc. if that helps.
In your defense, I did first google "Boston free clinic" and came up with a vet's office.
Anywho, I suggest you just start calling. I actually got rejected by a free clinic for volunteering b/c they didn't need any more help, but I don't have your credentials, so I was probably less useful.
