Kate Jonasse

Kate Jonasse is an ASE Master Certified Technician with over 18 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, GA 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 K-Tech Automotive, originally a one-woman operation.

As a child, Kate was the one in the house who was in charge of putting together anything that originally came in pieces - like tables, her kid brother's toys, and new appliances. She got into cars after buying her first vehicle, a 1981 Datsun pickup, which she bought for $600 (money she'd earned working at Subway during high school).

That truck consistently wouldn't start, and she used to park it on hills to pop-start it using the clutch. The situation motivated her to want to learn to work on her own car, so she would feel more competent and self-sufficient. With this background and attitude, a future auto shop owner was born.

But Kate's no grease monkey. She's a vegetarian, and she likes to cook vegan food. She also enjoys yoga, Aikido, running, and reading non-fiction. With her business, Kate strives "to boldly go where no one has gone before," so perhaps it's no surprise she's a fan of Star Trek: the Next Generation.

My name is Theresa and I’m the Office Manager for Kate’s shops. I’m a recent transplant to California from Atlanta, Georgia after 20 years, but grew up in Pittsburgh, Pennsylvania. I have over 10 years in the automotive field which includes General Management of Automotive Parts Stores, Outside Commercial Part Sales to Southeast Regional Product Sales Specialist. I’m the mother to 5 grown fantastic kids (that includes 2 sets of twins, 18 months apart) and grandmother to 5 wonderful grands (that includes 1 step grand). When I’m not working, I love spending my time hiking with my dog and discovering the beautiful places Sonoma County has to offer.

I'm Jonny, master mechanic and diagnostician here at K-Tech. Besides repairing vehicles, I enjoy spending quality time with my family at home on my off time. There's nothing I enjoy more than being a proud father of three. I'm a huge Giants fan and Chevrolet enthusiast. I also really like being outdoors and fishing and camping. I'm having a great time fixing cars here at K-Tech. I enjoy helping people with troublesome car issues, and figuring out complex problems with their vehicles.

I have been in the automotive industry for 20 years now and I love every minute of it. Making things better after I touch them is my passion. I learn lots of new things every day and I love that I have developed the skill and confidence of knowing about each car I work on. Cars have always been a hobby of mine and I have my dad to thank for that because he has been a mechanic for 40 years. The people at K-Tech are great and I am never afraid to learn something new. I love working here and am thankful for the great management and fellow teammates who have taught me many things over the time I have been here.
