Kate - Owner of K Tech Automotive, auto repair shop in Sebastopol CA

Kate Jonasse, Owner & Founder

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.

Monica at K Tech Automotive, auto repair shop in Sebastopol CA


Hi, my name is Monica! I started my automotive career in 2003 in a quick-lube oil station, washing windows and checking tire pressures. I quickly worked my way up to lube tech, and eventually became a full-fledged auto tech at a large franchise. I worked my way up to working at the front counter, then became assistant manager, service manager and finally store manager. I love cars and helping people. Helping people keeps me going every day.

Jonny at K Tech Automotive, auto repair shop in Sebastopol CA


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.

Brian at K Tech Automotive, auto repair shop in Sebastopol CA


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.

Diane at K Tech Automotive, auto repair shop in Sebastopol CA


I began working in gas stations 40 years ago. I've worked in a various aspects of the automotive industry. From parts sales, to dealership desks, as well as motorsports facility sales and guest services. My most recent position was as the Marketing Coordinator for a multi-line, high performance parts manufacturer. I currently own a small business called Vroom Vroom Girl that serves as a network and encourages women (and men) to explore the industry. In 2017, I had the incredible opportunity to be a part of an all female truck build to which 90 women from all over the country brought their skills. The truck was unveiled at the largest automotive aftermarket trade show in the world. I look forward to being a part of your automotive repair solutions.
