Diamond Hills Collision Center
Our company was founded in 2010 by two owners with a strong history in the collision industry. One brought his business acumen, experience in collision center management, and far reaching vision. The other is a technical expert who is a frequent sight at Buttonwillow Raceway where he continues to push his limits. Together, they assembled a team of professionals with a diverse background in automotive repair, automotive paint, collision expertise, and management. Utilizing the latest equipment, our OEM trained technicians are ready to repair your vehicle beyond factory standards. With two locations and over 80,000 square feet of production space, we look forward to serving you.
In an ever evolving world, Diamond Hills Collision Center looks to blend the past and the future. Willing to explore options outside of the traditional collision industry norm, the company is committed to delivering an unparalleled customer and repair experience – virtually and physically. Yet, we are also dedicated to maintaining the familial feel, care, and social responsibility of days gone by. Diamond Hills Collision Center is unwavering in our mission to not only repair your vehicle, but treat you as family.
To innovate and evolve the collision industry while providing exemplary service, quality of work, and peace of mind.
WHAT SETS US APART
Our goal is not simply to earn your business. Interaction with the local community, educating others, and making connections are what last. We are more than happy to share our knowledge, expertise, and professional opinions with our customers. Too often, we don’t have a minute to stop, think, and breathe. This is especially true when you’ve been involved in an automotive accident. Let us help you bear the load. To us, family and friends are what are most important in this world. We want to extend that level of care and compassion to our customers, as well.

Duwey Thi – Director of Operations
Possessing a nearly encyclopedic understanding of how to repair any vehicle is Dieu’s claim to fame. The man is a treasure trove of answers for anything repair and paint related. His role as the production manager for Diamond Hills Collision could not be more tailor made. Everyone from the body techs, to the parts department, painters, and the wash and detail team report to him. The company is incredibly lucky to have someone who not only manages, but also mentors. Several of our technicians started off as an assistant to Dieu who carefully cultivated, encouraged, and passed on his knowledge to them. Now, those same technicians are being certified by OEM’s such as Porsche. Kindhearted and genuinely pleasant to be around, Dieu is also a strong family man and spends most of his days off with them.
Jon Chou – Director of Business Development
Brought in for his corporate management and development skill set, Jon oversees Diamond Hill’s growth and expansion. Having worked for various firms across the country, he brings a unique perspective to a traditionally stagnant and older industry. Though much of his work is centered around long-term projects, one of Jon’s main tasks is to ensure the company is headed in the right direction. He makes certain that the management team is on the same page, that the owners’ interests and goals are being met, and that the business is healthy. When he isn’t running meetings or attending them, Jon can be found wrenching on his car or going for a run. Skydiving, tracking, and anything else that gets his blood pumping are favorite activities. When he wants to relax, he is happy to open a book or cook a gourmet meal. And, wherever he may be, his Shiba Inu won’t be far behind.
Rey Martinez – Auditor/Estimator Manager
With decades of experience in the industry, Rey confidently leads the company’s team of estimators and their assistants at all our locations. His wealth of knowledge regarding proper repair procedures, estimates, and negotiating with insurance is invaluable. That same familiarity with the industry lends him to be a perfect candidate to coordinate our OEM certifications and to ensure that we exceed any requirements and expectations set forth by our valued partners. When he isn’t busy at the office, Rey relaxes by spending time with his daughters and taking them fishing or camping. He’s also a master griller who graciously dives in and cooks whenever we have a company function. You haven’t had barbeque until you’ve tried Rey’s.

Coming from a strong financial background in banking, Wade handles the company’s finances and expenditures. Whether we are looking at purchasing new equipment or opening a new location, he provides the answers as to whether or not it is economically feasible.

It’ll save him a lot of trouble. Though the majority of his work is behind the scenes, his impact is felt at every level of the company. On his off hours you can find him underneath his E46 M3 track car, playing first person shooters online, or relaxing with friends and family.
