Revv Aviation and OptimuM AIR have signed an agreement to jointly provide critical care air transport services to the Southwest Region. OptimuMedicine, the parent company of Optimum AIR, operates out of Las Vegas, has provided critical care ground and air service in Nevada since 2017. That includes both ground and fixed-wing ambulance. Revv Aviation will fulfill the existing need with a dual-piloted King Air 200/350 and dedicated crew for 24-hour on-demand response.
