As a shop owner, you have the ability to tune into your shop’s performance metrics, employees’ bandwidth, and overall profit margins with a few clicks.
Lucas Underwood and David Roman, hosts of the ASOG podcast, recently sat down with Tekmetric CEO Sunil Patel at the Vision Hi-Tech Training and Expo in Kansas City, Kansas.
Sunil shared some key insights into facing challenges, embracing change, streamlining processes, prioritizing customers, and the power of “always starting with why.”
Note: the following answers have been condensed for clarity.
On Facing Challenges and Handling Stress
ASOG: We spoke with PJ Leslie (Tekmetric’s Business Development Director) recently, and he was talking to us about your ability to take anything that comes your way and overcome it.
PJ shared with us that no matter the circumstance, you’re always able to say, “We’re going to get through this, and we’re going to make something from it.”
You created an amazing thing despite the adversity that you’ve faced. How were you able to do that?
Patel: My wife and I went through some hard times with our daughter, Brianna, about a year ago.
And what I told my wife during that time was, “You know what? I’m ready to face this challenge.
We’re going to find the best doctor we can find and the best solution for her. And Brianna will live life one day at a time.
We’re not going to think about the future, we’re going to live life today.”
Since that day it’s been almost ten months and everything has been great. She’s doing beautifully.
A key component to handling stress is delegation.
You’ve got to let go of some of your responsibilities no matter how unnerving it is. Remind yourself that you can continue to keep your momentum on your shop, business, and goals by delegating.
That’s why you have a team—so you can tackle and conquer each task that comes your way.
On Embracing Change and Switching Gears
ASOG: You’ve gone from being a physician to a police officer to an auto repair shop owner, and now you’re the co-founder and CEO of Tekmetric. What made you want to go from physician to shop owner?
Was there a rock bottom for you? Was there a point where you decided, “I don’t want to be a physician any longer?”
Patel: I was fortunate that I never hit rock bottom. I’ve always tried to live in the moment. And I’m always intrigued by learning new things. With that being said, it took me going from industry to industry to learn the skills that helped form Tekmetric.
Let’s say you set a goal for yourself to go to the gym more often.
Now, if you don’t want to go to the gym, then you will keep training your mind to make sure that gym is just not your thing. It’s not until you have a breakthrough that you are able to change your mindset.
You have to train your reticular activating system (RAS), a network of nerve pathways located in the brain stem that mediates overall behavior, so that going to the gym becomes a positive activity.
Along with reminding yourself that you want to go to the gym, write down when you want to make the change and why.
Let’s say this is your goal, 'In March 2023, I will feel great, I will look great, my clothes will fit me better, and I can hear my family and friends saying ‘You’ve done a fantastic job.'
You have to recognize and reframe each limiting belief that is preventing you from achieving your end goal. An example of a limiting belief would be something along the lines of, "Ah, I’ve had a long day, I can just go to the gym tomorrow.' You have to reframe it to, 'I’ve had a long day, time to finish strong with a trip to the gym.'
You have to be very intentional. You truly have to want to reach the finish line.
This concept goes for shop owners, too. If you’re wanting to expand your shop, you’ll need to change the way you’re running your business. You can do that with shop management software.
On Company Culture and Customer Feedback
ASOG: What is different about Tekmetric from the other shop management software companies on the market? What is it about Tekmetric that your supporters latched onto?
Patel: I feel that our company, our culture, and our following, are very, very strong and hard to duplicate.
And early on, we got vocal shop owners on board with Tekmetric. They bought into Tekmetric, and they ran with it. And we’ve stayed in touch with them through the years.
Additionally, we always stay connected with our customers. It doesn’t matter how big Tekmetric gets. It’s a company priority that we will always make it a point to talk to shop owners. We want to get that face-to-face time with them.
We want to see what’s bothering them, and we will never lose sight of that.
Along with talking to shop owners, we’ve always made sure that we listen to what they’re saying.
We were the first shop management software to incorporate a user group where we can actually get feedback from shop owners and have them vote on features that they would want to see in our software.
We did it manually through a Google spreadsheet at first.
Now, we have a customer success team that focuses on customer feedback.
ASOG: Everybody says it’s their company’s culture that makes them stand out. What’s unique about Tekmetric’s culture?
Patel: Some of the people on our team have been with us since day one.
And in addition to listening to our customers, we also listen to our team. As a company, we’re constantly improving our internal processes.
We never rest.
The processes that work for us today won’t work for us tomorrow—when we’re a 20-person team vs. a 50-person team vs. a 90-person team. It’s a process of constant change to make sure that we’re doing everything to the best of our ability.
On Implementing Shop Owners’ Feedback
ASOG: With customer feedback being a priority for Tekmetric, how do you balance Tekmetric’s features to avoid getting to the point that it’s overloaded with hundreds of buttons that do hundreds of different things?
Patel: Software matures over time. You're constantly bolting on features—over and over and over. However, you don't want to have this very complex software with unlimited buttons that do every single thing you can think of. It needs to be in a streamlined formatting process where you solve the issues that the shop owners are having along the way.</p>
Simon Sinek’s book, Start With Why: How Great Leaders Inspire Everyone to Take Action, is fundamental reading for our team. When we get a request saying a shop owner wants a purple button here and a blue button there, we have to be able to drill into why they want that change to begin with.
The buttons shop owners are asking for may not actually be what they need. It could be something completely different and unrelated. </p
At Tekmetric, we don’t want to do something that has been done in the past by somebody else. We’re not trying to just duplicate systems and call it a day. We want to know how we can make things even better.
We want to make the lives of shop owners easier.
As shop owners, we really resonate with this in a lot of ways. It makes a difference to hear, “This is why it's going to help you,” and actually see the difference it’s going to make within the software.
When I ran a European shop in Houston, there were times in the beginning of 2007 where, as we were just hitting the mortgage crisis, I was outsourcing myself to make the right choices business-wise, and I was pushing myself to get customers through the door.
Something that helped us immensely was adding a glass wall in our shop.
Our customers were able to see where their cars were in the repair process; they were able to see the technicians hard at work. It instilled a level of trust with our customers, and that’s how we got our following.
Transparency is key. We’ve placed transparency at the forefront of everything Tekmetric does for shop owners, their teams, and their customers.
On Finding Your Way
ASOG: Anything else you want to say to the listeners?
Patel: I enjoy getting my leadership team to think of better ways to solve problems.
We’re not going to sit and go on and on about how problems have been solved in the past. There are always better approaches.
And I wish more shop owners would realize that there’s always going to be a better way. You can reach your goals, fine-tune your shop’s processes, and give your customers the experience they deserve.
We’ve seen shop owners go from virtually nothing, going bankrupt, to making almost six figures a month.
And most importantly, never be afraid to ask for help. There are great resources out there to help you find your way.

This guide will break down the most recognized certifications, how to attain them, and why they matter for every auto mechanic who wants to stand out.
Types of mechanic certifications
Mechanic certifications come in many forms, each tailored to different specializations and career goals. The most common types include:
1. ASE Certifications
Issued by the National Institute for Automotive Service Excellence (ASE), these certifications are the gold standard for automotive mechanics. They cover a wide range of specialties, from engine repair to electronic systems and air conditioning.
ASE certification is considered the most prestigious and widely accepted credential in the automotive world.
More about ASE
Founded in 1972, the National Institute for Automotive Service Excellence sets the benchmark for automotive service technicians. ASE offers over 50 different certification tests in categories like:
Engine Repair
Brake Systems
Air Conditioning and Heating
Suspension and Steering
Electrical/Electronic Systems
Engine Performance
Manual and Automatic Transmission/Transaxle
Light Truck and Diesel Engines
Master technicians
There’s also a separate path for master technician status, which is achieved by passing all certifications in the required testing areas for that series. For example, technicians certified in tests A1 through A8 are Master automobile technicians.
Master technician status is not for life. You must keep each one of those certifications current to maintain master technician status. If you lose master technician status due to the lapse of one or more required certifications, it can be reinstated by taking and passing the recertification tests.
How long does it take to become ASE certified?
To become ASE certified, expect to spend anywhere from 1–3 years, depending on your work experience and whether you’re currently enrolled in training programs. Each certification test typically takes 1 to 2 hours to complete and can be scheduled at a local test center.
Being ASE certified shows you’ve mastered the skills needed for the job. It’s a badge of excellence recognized by employers, repair shops, and even customers looking for reliable service.
2. Student certifications
Geared toward high school and post-secondary students in automotive technology programs, these ASE certifications offer a head start in proving foundational knowledge.
What are student certifications?
Student certifications validate entry-level knowledge in core areas of vehicle repair and maintenance. These don’t require work experience and serve as a stepping stone to full ASE status.
Programs approved by the ASE Education Foundation often include student certification exams as part of their curriculum. These are excellent options for students at auto mechanic schools or in a community college training program.
Student certifications are valid for two years and help you build confidence before entering the workforce as an entry-level technician.
3. Manufacturer certifications
These certifications are specific to vehicle manufacturers and offered by companies like Ford, Toyota, GM, and others. Often, auto technicians working in dealerships will pursue these to show mastery of brand-specific systems.
For repair technicians who want to specialize in a particular brand, manufacturer certifications are essential.
Manufacturer training programs
Toyota T-TEN
Ford ASSET
GM ASEP
Honda PACT
BMW STEP
These accredited programs often partner with dealerships to offer real-world, hands-on experience while you earn your credential. These programs can take anywhere from 12 to 24 months and typically require completion of automotive technology coursework alongside on-the-job work experience at a brand-affiliated repair center.
Why they matter
Manufacturer-certified auto technicians often have a faster path to high-paying roles within dealership networks and brand-specific repair shops. These certifications also prepare you to service increasingly complex vehicle systems, especially as brands continue to innovate with hybrid and electric vehicles.
4. Specialty certifications
You’ll also find credentials related to diesel engines, heavy truck systems, collision repair, and even hybrid/electric vehicles.
Each of these certification types plays a unique role in an automotive technician’s career path, and in many cases, earning more than one will make you significantly more marketable in repair shops and beyond.
Depending on your interests, you may also want to pursue:
A/C Refrigerant Certification - Necessary if you want to be able to to buy refrigerant and work on air conditioning service.
Diesel Mechanics Certification – Focused on diesel engines used in commercial fleets and heavy truck applications.
Collision Repair Certification – Great for auto mechanics looking to work in body shops.
Hybrid/Electric Vehicle Certification – A growing field with high demand.
Each of these certifications typically requires completion of a specialized training course and a passing score on certification exams. These programs may be part of a broader certificate program or offered as a standalone credential.
Tek-Tip: Another way to get ahead as a young technician is to be experienced with auto repair shop software so your employer doesn't have to teach you how to use their system.
Benefits of mechanic certifications
Getting certified is one of the most direct ways to turn your hands-on experience into a long-term career asset. Mechanic certifications do more than look good on a resume—they deliver real-world advantages. Here are some of the benefits of completing automotive certifications:
Increased Pay: Certified mechanics typically earn higher wages. According to the Bureau of Labor Statistics (BLS), certified automotive mechanics can earn higher hourly rates, especially in competitive markets.
Job Security: The more certifications you have, the more valuable you are to auto repair businesses.
Professional Credibility: Certification demonstrates a commitment to quality and standards, building trust with customers and employers.
Career Advancement: Certified automotive service technicians are more likely to advance to roles such as shop foreman, master technician, or service manager.
Mobility: Certifications make it easier to move between different types of employers—whether that’s independent repair shops, starting a mobile mechanic business, dealerships, or specialty service centers.
What does the certification process look like?
Most mechanic certifications follow a similar pathway but always refer to the specific instructions for your program.
Step 1: Enroll
Start by enrolling in an automotive technology program. These are offered by community colleges, trade schools, and accredited auto mechanic schools. Many programs are supported by the ASE Education Foundation, ensuring alignment with real-world industry standards.
Look for certificate programs or associate degrees that offer hands-on training. Financial aid is often available for eligible students.
Step 2: Gain work experience
Work experience is critical for most certifications. For ASE certification, for example, you need at least two years of on-the-job experience—or one year plus a diploma from an accredited program. You’ll need to show that you’ve worked on everything from brake systems and axles to manual drive train repairs and electrical systems.
Step 3: Pass certification tests
Most mechanic certifications require passing written or computer-based certification exams. These are typically held at a certified test center. The exams cover a variety of topics depending on the specialty, including engine performance, electronic systems, and automatic transmission repair.
Tek-Tip: Some auto shops/employers will pay your test fees for you.
Step 4: Maintain certification
Many certifications require recertification every five years. Staying current ensures you’re up to date with the latest automotive repair techniques, tools, and systems.
