Kat, Shop Manager

My name is Kat, and I moved to Sonoma County in middle school. I have 6 children and have an amazing husband. When I am not at work I love spending time with my family and participating in my church. I am so excited to meet everyone who comes into Pauline's and help get people back on the road in safe vehicles.

Kate Jonasse, Owner

Kate Jonasse is an ASE Master Certified Technician with more than 20 years of automotive repair experience. Diagnostics is her specialty, and to this day, she loves solving problems.

Kate went to tech school in NY State (where she’s from), and was recruited by a Mercedes-Benz dealer in Atlanta, Georgia to receive factory training.

After several years working as a Mercedes technician, she moved to the West Coast, got her California smog license, and opened her first automotive shop, originally a one-woman operation.

Six years later, Kate took over Paul’s Automotive and renamed it Pauline’s Automotive.
