Next Service Smart℠ Saturday: April 18th!

Professional Auto Care Since 1983


In The Beginning...

In The Beginning...

Our principles have remained the same. We feel we have a fiduciary duty to advise our clients honestly and offer services at a fair price for quality labor and parts while providing an environment for teammates to thrive and accomplish their professional goals. 

Professional Auto Care was started by a husband and wife team back in 1983.  Everardo and Claudia are still involved with the operation of the business. Karolena, Everardo and Claudia's daughter, runs the shop day-to-day.  

In The Beginning...

In The Beginning...

In The Beginning...

The philosophy has stood the test of time.  

By developing an honest relationship with our clients we can better understand their needs and advise them accordingly.

Other shops have come and gone but the systems developed at Professional Auto Care are as applicable today as their original iterations were back in April of 1983. 

While other shops focus on repairs, we always have focused on THE CLIENT AND MAINTENANCE

...Still Running

In The Beginning...

...Still Running

Our primary purpose is to help people understand and take care of their car by giving them all the information and options needed to make an appropriate decision fitting their needs through the Service Smart℠ program. 

Founder and co-creator of our system grew up on a farm and understood when you take care of something it will last and if you don't , you may have a bad season. The same principle applies to cars! Take care of your car and it will take care of you!

Meet the Founders

Everardo and Claudia Serratos

Everardo's love for cars has been with him ever since he was a child. With some pals, he built his first car at age fifteen and they raced another team from a rival school. He attended and completed automotive technical school before moving to the United States. When Everardo first came over to the States he began working on Rolls-Royce and other high end luxury vehicles by day and attending the University of Houston by night seeking a degree in computer science. When the opportunity to own his own shop arose, he took a leap with his wife, and they became business owners.

Claudia's involvement with the automotive industry began when she was a child as well. Her father owned a successful parts store in Argentina. When she was young, she would often sort and pull various items or work the register (even before she could count!). When Claudia first came to the States, she was involved in Hotel Management, but when presented with a chance of becoming a business owner and specifically starting an automotive garage with her husband, she seized it. 

The husband and wife team started Professional Auto Care back in 1983 and they continue to have a strongly felt presence in the day-to-day operations of the company. The duo has always felt that family is important and so they involved their children in the business.

About Professional Auto Care

There is no such thing as over-night success

Our automotive repair shop has undergone many changes since the 1980s. When we first opened in 1983, the shop was half the size of today’s main building at 9916. Even this expansion proved insufficient so in the mid 90’s we purchased the lot of land across the street (9913) and constructed a much larger building – more than double 9916’s size! With all the space, we were able to store parts elsewhere and turn the parts room into an open concept office for our service consultants and writers.

In the early 2000’s, a concrete parking lot was poured down as more and easier client parking became necessary. When the concrete had just been poured, Karolena and Kimberly signed their names and pressed their hands into it. You can see their handprints and names on your way to our 9913 waiting room. The waiting room was built in 2007 and gave our clients much more space to relax and do what they needed while waiting for their vehicle to be maintained or repaired. Around 2012, we moved our inventory into two large containers. The containers have proved most useful because different manufacturers have begun to require specific fluids in recent years.

Fast forward a few years and we have three maintenance bays, one alignment bay, two dedicated Service Smart℠ check out bays, one dedicated inspection bay, two minor repair bays, five major repair bays, and two detailing bays, and a super comfy waiting room for clients.

I will not use any other auto repair shop but Professional Auto Care from now on. Professional Auto Care does professional and precise work that is guaranteed."

Marceal owner of 1991 Ford Tempo

Angel owner of 2008 Chevrolet Silverado

"I come [to Houston] every 1,000 miles every 3 months for medical care. I could have my routine maintenance done at home, but I prefer to return to PAC as I know they will not try to sell me an unneeded repair or maintenance. They have my car's record of maintenance as well as future anticipated needs on their computer and we discuss what needs work now, and what can wait."

Marianne owner of 2013 Chrysler Town + Country 

"Wonderful! Very female forward which is a nice change to the norm. The level of professionalism is very high as well as the attention to detail. I love the detailed reports with pictures. By the time I'm done reviewing the materials for each issue I feel as though I have a full scope of the work and that it's rational and supported by evidence. I've never had that feeling in a shop and it's very nice when you're handing over significant money. I think I've taken my car there 4 times and 3 of the times they washed and vacuumed the inside of my car without me having to ask, just as a courtesy. A very nice touch in addition to their amazing waiting room, free WiFi, etc. I also enjoy being able to see the parts that were replaced after each round of work so it all comes together visually what was needed and done. I won't be going anywhere else for a long, long time!

Andrew owner of 2009 Honda Odyssey

"Very good job!"

James owner of 2011 Land Rover Range Rover

"Exceedingly well. The people I have worked with at PAC are scrupulous and charge fair prices. They go the extra mile to make sure that you understand and are satisfied with the process. The shop is open and tidy and you get the sense that there is nothing to hide -- they just do good work."

Michael owner of 2006 Ford Fusion

"They found an obscure problem with the brakes that could have cost us a repair on the road. That's why we use PAC. They're reasonable, honest, terrific communicators (hats off to Karolena!) and they really know their stuff."

Sue owner of 2005 Chrysler Town + Country

"Great as usual. Very friendly staff and technicians. Explained everything clearly what was done to my truck. They did the oil change in a timely manner. I take both my vehicles there and would recommend to everyone."

Daniel owner of 2012 Toyota Tundra

"Everything is working fine at the moment. Thanks for the follow up!"

Rae Ann owner of 2002 Infiniti G20

Allen owner of 2004 Nissan Quest

"This pic of what's growing in the sample of fluid from my ac is simply gross. I was sure there was something wrong. You can use it for your records. My ac doesn't smell anymore. I'm happy I did clean it!"
Iwona owner of 2016 Mercedes C300

The car felt brand new, which was a pleasant surprise. The car has been sold and I am happy knowing the car is good to go for the new owners. I gave them the receipts of all the work done and told them if anything comes up to give you guys a call. Thanks again for everything."

I have decided on a 2019 Subaru Forester Sport -- probably gonna complete the purchase today. Thank you for helping me out with the discussion. I really appreciate how straightforward and approachable you and your staff are with advice, repairs and everything. Normally in mechanic shops there seems to be layers of BS and y'all don't have any of that. Thanks for your professional friendly service. We will be back for sure."

I also love how my van, "Cindy," comes back to me better than ever each time I leave her with you! I feel like you even wash her and/or vacuum her a bit! I feel valued here. The waiting room in the building across the street was so great this time!! It's great every time, but this time, my eight year old (who LOVES the car rug and the car models) and I noticed not only were there drinks in the fridge, but there were snacks for us, too! LOVE that."

When I need the pros, I feel I can trust Karolena and her team to give me fair prices and do great work. Suggestion: I would like to be able to easily see a service history report.
