Dan Spiegel in Los Angeles, CA on Houzz

Dan Spiegel and Christopher Hollenbeck founded DMS Contractors, after previously growing companies like CH Construction. Together, Dan and Chris have over 60 years of experience.


DMS Contractors prides itself on maintaining the highest quality of service in all phases of the construction process.

Compared to other construction companies, DMS Contractors goes above-and-beyond by providing unmatched communication skills, from the beginning of a project to the end. In doing so, DMS ensures that home/business owners, architects, subcontractors, and other involved parties remain up-to-date on all aspects of the project. DMS provides its clients with unique, personalized and locked blogs, through its website, that provide pictures and updates from start to completion -- a communication tool unique to DMS. By providing clients with these personalized "portals," DMS ensures that its clients readily have access to all details of a project in progress. 

In addition to excellent communication, DMS prides itself in the quality of materials and our fine attention to all details. We make sure that every project is completed to the highest of standards.

At DMS, many of our subcontractors have been with us for several years -- some as many as 20. In addition, most of our in-house staff is family, ensuring trust in all of our staff. Every member of the DMS team, from subcontractors to Dan and Chris, is screened to make sure that they live up to our standards of excellence, including impeccable work quality and unmatched communication skills.

By using DMS for your next project, you're not only counting on us as a company, but as a family that takes pride in all of our work.

When receiving a bid from us, please be sure you are comparing it to companies that meet the same quality of work.

I have worked with DMS for over 25 years. They have remodeled rooms, added rooms and helped me with complete renovations as well as assisting with the construction of pools and new buildings.

I cannot recommend them any higher. I would rate them a ten out of ten. They are artistic, ethical and moral. They are hard working nd completely reliable.

PERHAPS MOST IMPORTANT, THEY DELIVER. What they say is what they do. That goes for cost and for quality. When they say they will do something, it is done exactly as they design and finish. If there are any surprises, they warn me and discuss solutions.I would use them for new or renovation construction; from the planning to the finish stage. I stake my own reputation on these facts.

I have worked with DMS and recommended them to several of my clients and they continue to impress. They are prepared for any situation, thorough, professional, easy to work with, clean, and most importantly on budget.

I would recommend DMS for any scope project you may have. Their quality of work is unmatched in the industry.

I cannot emphasize enough how amazing DMS contractors are. Every aspect of my house was organized and finished with style and confidence. I will work with them exclusively on all of my projects. Their customer service is unparalleled and unlike most contractors, they are responsive and are real team players.

I have hired DMS for multiple projects of mine and I cannot say enough about the quality of craftsmanship to the great communication they display through every step of the way. This has ranged from a complete remodel which turned into a BEAUTIFUL home to also a couple kitchen and bath remodels. Dan and Chris at DMS always do a wonderful job of communication and more importantly even do VERY high end work which comes out about as nice as you can get it! This is why I continue to go back to them for my needs whether on my own home or on spec houses that I have done. I’m always skeptical to recommend contractors but they have earned my trust over the years!

Dan Spiegel
Founder, Co-Owner

A native Angeleno, Dan began his professional career as a platinum smith, working in his family's business. While working as a jeweler, Dan began moonlighting in various construction jobs. For years after, Dan worked as a finish carpenter and later transitioned into a foreman role, where he specialized in recording studio remodels and the construction of high-tech, custom home theaters.

In order to venture out on his own, Dan obtained a general contractor's license. While Dan's construction knowledge and experience is diverse, he is highly skilled in finish carpentry, rough carpentry, cabinets and drywall. Dan's experience in construction spans all type of architectural styles, from Gothic to contemporary. 




Christopher Hollenbeck

Originally from Syracuse, New York, Christopher Hollenbeck grew up in and around the construction business, as his father was a prominent building contract in Central New York. In 1983, Christopher gained his own general contractor's license and established the company C.H. Construction in Los Angeles. 

Over the many years since creating C.H. Construction, Christopher has developed a network of highly-qualified sub contractors, craftsmen, vendors, architects, and other professionals -- connections and experience he carried to DMS Contractors. Many of DMS Contractors current employees have worked for Dan and Christopher for over 20 years. Christopher's in-depth knowledge of construction and affable personality allow him to communicate effectively with each person involved in the construction process.
