“For the past 15 years we've had numerous successful forensic projects working with Bethco Builders. They are always responsive, timely and willing to assist on a moment's notice.” 


Private Residence, Oak Knoll Area of Pasadena 

"We had a major dispute with our original contractor over the quality of work. In preparation for our litigation, we engaged Dave Bethany of Bethco Builders to conduct some forensic assessment and destructive testing of the work that had been done, and to recommend remedial plans and estimates.

Dave and his team did a very thorough and professional job in supporting our construction lawsuit.  He and his team were extremely experienced, professional, efficient and thorough throughout the process. They quickly identified what areas needed to be opened up, and took meticulous records with written notes, photographs and videos. Their final report was both comprehensive and compelling, and served as the strong evidence in support of our claims.

We found Dave to be very knowledgeable, experienced, organized, responsive and, most important, highly ethical.  In fact, once the legal process was over, we decided to hire him and his team to do the actual repair work as well, which has been done to spec, within budget, and on-time.  It was a real pleasure to work with Dave and his team."


Founding Director of the PACIS Project in Faith Based Diplomacy at the Straus Institute of Pepperdine University School of Law

“Dave’s easy manner and leadership allows him to become part of the planning / policy team seamlessly. His profound knowledge of the field allowed for insightful and creative options. As an expert witness, Dave was unassailable knowing not only the client’s point of view but the perspective of the other side as well… and then became an advocate for a comprehensive mutually satisfactory outcome. Dave has enormous energy, empathy and focused attention and commitment to the work at hand! I’d hire him again, in a NY minute!” Mr. Pownall has known (and hired) David Bethany since 2005 and thinks his top qualities are: “Great Results, Expert, and High Integrity”

Brian Daly

President, Hygiene Technologies International, Inc.

“I have known and have worked with David and others at his firm, Bethco Builders for over ten years. I am a senior level industrial hygienist and I am occasionally hired as an expert by law firms that have also hired David because of his expertise in construction and his capabilities as a construction expert. I believe that I have worked in that capacity with David one or more occasions every year of the past decade. David has consistently demonstrated a high level of professionalism and knowledge, not only of construction, but also of abatement needs, costs, and of other matters that are of critical importance to cases involving construction defect or other related matters. David and his colleagues at Bethco are “top drawer” construction experts and I have enjoyed my professional relationship with he and his firm.” 

Grace Fogg Miranda

Leader of The Miranda Team at Keller Williams Realty

“David Bethany is one of the most experienced and capable contractors I have ever had the pleasure of working with. He has consulted me and my clients on a wide range of construction challenges over the years, including a particularly memorable home with severe earthquake damage. (My clients wisely moved on to purchase a different property!) David has a great work ethic and honestly seems to know how to do almost anything. I would highly recommend him.” 


Past President, View Ridge Townhome Owners' Association Board of Directors

“Over a period of three years, our homeowners’ association worked closely with Dave Bethany and his company, Bethco Builders, on a multimillion-dollar renovation to our Pools, Tennis Courts, Private Streets, Roofs, Landscaping, Drainage and Fences. Dave and Bethco were responsive to our concerns, timely in their responses, and always honest and complete in their recommendations. Keenly aware of the unique needs and problems related to HOAs, Dave and his company were able to anticipate our questions and requests, and were always prepared to make the process as easy as possible for our homeowners. As President of the Association Board of Directors during the renovation, I was able to cope with the demands of the position because Bethco Buildings was always available and helpful – we could have not have done it without you!” 


President of Cascade Builders & Consultants, Inc.

“If there is anyone who can vouch for Dave Bethany’s integrity and honest business practices, it would be me. When you partner with someone in business for eleven years you get to know them very well. […] Our success was only made possible in our commitment to our clients and each other. We have since moved on to our own ventures and I have watched Dave build a very successful business of his own. Success is only built with sound principles that include honesty, integrity and trust. If you want someone who you can trust to do the job right and carry honesty and integrity throughout the process, I can say that Dave and his team will provide you with those very important characteristics.”


CCAM Association Manager

“As manager of many community associations, I have worked with several vendors and tradesman. In the course of the past 2 years, I have had the good fortune to have been recommended to Bethco Builders. What began as a very difficult case of defect litigation became a much easier prospect after hiring Bethco Builders. From the destructive testing to the actual mediation, then construction management, all aspects have been smoothly executed and the burden of the process taken away from my Board of Directors and management. The construction crews that Bethco Builders have helped to engage, have exceeded expectations as well – all part of a service I would highly recommend. I would be happy to discuss any of the details of working with Bethco Builders at any time.”


Manager at Century Towers

“Thank you for resolving the matter with the Engineer. Your idea to offset his cost of redrawing new plans for the one configuration by giving us a credit on the first set of plans was ingenious. As Joe and I told you at yesterday’s meeting, both the A/C Drain Project and Gym Project are going very smoothly.  […] How pleased we are with your performance as Construction Manager and as General Contractor. Going back to the cooling tower / roof job from five years ago to the electrical system near-disaster you helped us avoid last year, we kept finding ourselves in the position of thanking you. So this time is no different. Just so you know, we truly appreciate your ability to keep our costs down, keep our homeowners happy, and execute high-quality work on projects that end up being a lot more complicated then we first thought. Keep up the good work Dave!”


President of McDaris Construction, Inc.

“I have known David Bethany for over 30 years. He is a very competent builder in both field operations and project management. In David, you will find someone that you can rely on to listen to your ideas and give you direction on how to accomplish them.”
