American Medical Response acquired Rural Metro October 31. The company's regional CEO Thomas McEntee says more ambulances will be on the street during peak hours.

"We understand that if there's folks out there that may have lost confidence we're going to restore that and we're going to win back their confidence and we're going to exceed their expectations," McEntee said.

The new contract with Buffalo mandates better response times from the ambulance service.

McEntee says new ambulances and other equipment is also on the way.

The Colorado-based company serves more than 2,100 communities in 40 states and the District of Columbia.
