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.

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


My name is Adriana. I have two beautiful daughters, and am a very proud mother. I enjoy being outdoors, whether I'm hiking, fishing, camping or just playing in the park. I am a huge sports fan! I pride myself on my customer service skills as I have over 10 years of experience. People tell me I am very kind and friendly. I love being part of a fantastic team here at K-Tech. Being a woman and having two daughters, it is very important for me to show them that as females we can be a part of the automotive industry.

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


I have been in the industry for about 4 years now and I love every minute of it. I can say that there is no job like this where I can learn lots of new things every day and have the 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. I love working at K-Tech and am thankful for the great staff and fellow employees who have taught me many things over the short time I have been here.

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.


My name is Jose. I'm a mechanic by trade and by choice. I love what I do and I'm always happy to see the look on a customer's face when we fix their car's issue. I'm also a big Raider's fan - I love the game and can't wait for it to come back next season. In my off time I like to fish and spend time with my wonderful family. I love it here at K-Tech, and could not ask for a better working environment to come to every day.
