Meet Our Staff

Mike Pfeiffer | Certified Transmissions, Inc.

Mike Pfeiffer, AAM

Owner and President: ASE Master Tech, Service Consultant, and Parts Specialist

Mike Pfeiffer, the owner of Certified Transmissions Complete Auto Care, grew up in Wisconsin. Mike and his cousins grew up with grease on their hands. Right out of high school, he went into hardware, and got his business sense working in retail. He was assistant manager, with 105 people underneath him, selling hardware. Working 65 hours a week, his uncle advised him to change careers, and asked him to work for him. So he quit (his wife was pregnant), and went to work for his uncle. He was mechanically inclined and had a solid business background.                                             

Mike and his wife took a bus tour to the Grand Canyon, had an extra day, and went to Prescott. They fell in love with Prescott. He knew there was plenty of opportunity. That was 33 years ago. 33 years later, as of March 25, 2021, here he is making a living in Prescott! Mike had many certifications, so decided to name the business Certified Transmissions.
