"Powertrain Integration selected McCullough Public Relations to be our agency because we had witnessed their effectiveness in the aftermarket performance industry. MPR learned our core business of medium duty trucks quickly, especially considering that PI serves segments ranging from delivery vehicles to school buses, with the complexity of multiple fuel types added in. MPR has built genuine rapport with key media people. Big announcement or small, traditional or new media, MPR always applies the same keen attention to detail and follow through, constantly looking for ways for PI to be relevant and creating strategies to stake out and convey our messages."
