I used to live and work in Buffalo. The Buffalo/Niagara region has 2 main Ambulance companies. The 1st and biggest is Rural/Metro Medical services http://www.ruralmetrowny.com Rural Metro Western NY which covers the city of Buffalo, city of Niagara Falls, Cheektowaga, Hamburg, Orchard Park, West Seneca, Medina, etc. They have over 500 field employees. The 2nd is Twin City http://www.tcaems.com Twin City which covers Tonowanda and Amherst. I worked for Rural/Metro. it wasn't too bad.
Why do you want to relocate to Buffalo?
If you have any other questions or anything just ask or email me. I worked there for 4 years. I got my Intermediate and Paramedic there as well.
