Lisa Carter

The feminine presence at Water Star Motors.

Does being a ballet major pay off? Yes! Lisa's experience as a ballet dancer lends grace to whatever she does. Initially, Lisa got her hands dirty under the hood assisting husband, Henry, with car maintenance, repairs and advising. However, now the business has grown to the point where Lisa and Henry have a team of highly trained technicians and service advisers to assist them, Lisa is able to focus on issues behind the scenes, including directing Water Star Motors' marketing, finances and writing Rock, Paper, Car for Santa Cruz Weekly as well as Waterstar's Blog: The Sage Mechanic.

Says Lisa: "It is so good to work with such a great team of smart, harmonious hard workers. They are my Clean, green, auto repair team!"

Lisa is an advocate for sustainable living (let's save our planet one person at a time). She is a great listener, organizer and get-it-done kind of gal. Lisa not only loves to meditate herself, but she teaches meditation classes as well.

Brush Fire

Anecdote (Short account of a funny incident/event in auto repair or other): Sometimes it is the simple things that can fix a car. On example is a truck came in the other day with a ‘no power on the freeway’. As you can imagine, this can be very scary. The funny discovery was that the floor mat had creeped its way under the throttle in such a way as to prevent full acceleration.

June, 2018; I saw smoke within the block of our shop and called 911. They asked me to confirm if there was an actual fire. Meanwhile, my technicians ran around the corner, confirming it was a brushfire. I handed them a fire extinguisher over the fence. They problem solved by using a hose from a house near to the fire and were successful in putting out the fire. They saved the nearby home as well as acres near the levy. I was able to put this article in the SC Sentinel.

Stephanie Underwood: Service Advisor

Stephanie Underwood

Aspirations, beliefs, or goals as a human being: I believe in treating others how I wish to be treated. My goals in life are to do my best, try hard, and enjoy life. As a human and mother, I want my son to have faith in himself and not be scared to speak his mind.

Experience, Education, Credentials, Achievements: I’ve been working in automotive repair since 2015. Starting as a lube technician. I trained my way up to Service Advisor. I am an ASE (Automotive Service Excellence) Certified Service Consultant. I have completed Level 1 Engine and Control Emission control fundamentals and Level 2 Smog Check Procedure training. Also, I have earned Certification in Social Justice, and enjoy working with and helping people.

Unique Quirks, Soft Side of Personality: I love being a mother, friend, sister, and a woman. When I’m not working you most likely will find me with my son or curled up with a good book.

What you bring to Water Star Motors: I’d say I’m hard working, quirky, and a little bit of a clean freak. But I will always greet you with a genuine smile and a helping hand.

Anecdote (Short account of a funny incident/event in auto repair or other) A dangerous car problem I see sometimes is when the brake pads and rotors are worn-out beyond belief. Most people are good about replacing pads when they start to squeal, or the light comes on the dash. But others keep driving until they can barely stop at a red light. I've seen rotors worn down to their vanes, or so rusted that they snapped off the carrier. A few times I've seen brake pads worn past the metal backing. This means the piston was the braking surface. Yikes! It's crazy how people play with their safety like that.

Troy Bierman, Technician

Troy Bierman

Aspirations, beliefs or goals as a human being: I believe in treating others as I want to be treated. I am number one, but everybody else comes first. I love good manners – Please, may I, thank you. I strive to be the best human being I can be (by thinking first)

Experience, Education, Credentials, Achievements: With 25+ years’ experience, I feel every day is some sort of education. I learn something new every day. If you aren’t learning something new, your eyes aren’t open wide enough. I finally went sky diving with my two awesome daughters, and I am sure many more great things are to come.

Unique Quirks, Soft Side of Personality: I am totally interested in all things in life such as Bonsai, and Origami. I love the beach and making crazy sand sculptures. Now I have found a passion in sky diving and want to get certified and put on a wing suit!

What you bring to Water Star Motors: I am a willing and able body with great wit and humor. Plus, I have critical thinking skills, mechanical smarts and dedication to the company.

Anecdote (Short account of a funny incident/event in auto repair or other): Nothing funny, just a non-thinking moment. I was doing a clutch and spacing out on putting the pressure plate and clutch disc on before putting the transmission back in. (Hey, what is that on the floor over there? The clutch kit!) Ha, ha. No big deal – take the transmission back out and do it right!

Ben Marzan, Smog Technician

Aspirations, beliefs or goals as a human being: To become a great auto repair technician and a good person to everyone – especially to my family.

Experience, Education, Credentials, Achievements: 17 years working in restaurants as a dishwasher and line cook. Also, I have worked almost 30 years on cars as a mechanic and smog technician. My college degree is as a Marine Engineer from the Philippine Maritime Institute.

Unique Quirks, Soft Side of Personality: I treat my dog and my cat the same way I treat my children. Lots of love.

What you bring to Water Star Motors: My vast experience as an auto mechanic and smog technician. I also like working with this super team.

Anecdote (Short account of a funny incident/event in auto repair or other): At another shop, I was helping a new mechanic with a clutch job. “Just ask me if you need any help,” I say. The next thing you know he had the clutch back in the vehicle already. I thought to myself – that is a bit too fast. I looked around and saw the pressure plate was still on the floor. Fortunately, I caught it in time for the other tech to undo and redo the job.

Cade Martin-Hansen – Shop Helper

Aspirations, beliefs, or goals as a human being: I believe that we should all try to act in a way that promotes the behavior we would like to see in the world around us.

Experience, Education, Credentials, Achievements: I graduated from SLV High School in 2021 and completed my first year from Cabrillo College. I have been working at Water Star Motors for 1.5 years. They are teaching me so much about how cars work and how to work on cars! I appreciate this learning opportunity.

Unique Quirks, Soft Side of Personality: I really Like plants and can name/identify most of the native plants in our area. I especially love the wildflowers as I hike.

What you bring to Water Star Motors: What I bring to Water Star Motors is a positive attitude and kindness that I hope makes it a better workspace for my teammates and customers.

Anecdote (Short account of a funny incident/event in auto repair or other) Every time I can’t find a coffee cup before work in the morning, I will find every coffee cup I own at work. Hilarious.
