“KA Enterprises brought on Black Diamond Construction to handle a big exterior renovation job for a 47-unit apartment project in North Park, San Diego. To say that working with Black Diamond was key to the project’s success would be an understatement. They were extremely professional, patient, diligently explained the process and executed on the challenging business plan.” 

-Eugene Marini, Director of Acquisitions / Asset Management

“Devin and his entire team have done such a great job for us over the years at the Terraces at Copley Point, and also did such a great job directly for our main tenant, Guild Mortgage, as they recently expanded another 60,000 sq ft.

I am happy to help describe the great experiences we had all the way around, including all the extra “design” help that Black Diamond provided for free.” 

-George Yermanos, V.P./Director of Property Management Sudberry Properties

“When Guild Mortgage C o was looking to buildout floors 1, 3, and 6 (120,000 sq ft) of the building we signed a lease for, located at 5887 Copley Drive, we reached out for 3 bids and made the decision to go with Black Diamond.

The Property Management had Black Diamond do work in an area of the building and highly recommended Black Diamond. In addition, the bid was the most competitive. We saw the work that Black Diamond did on behalf of the property management and it was beautiful.

Black Diamond was the best choice we could have made, not only is the work that was done stunning, the project coordination, status updates, commitment to the job, attention from Devin, Robert, Juan and all staff was over and above. I would highly recommend Black Diamond.” 

-Karla Bowen, Facilities Manager Guild Mortgage

“I have worked with Devin and his team at Black Diamond Construction for 4 years and they have always been a pleasure to work with. They have built out multiple TI’s for our tenants (in excess of $3 million) and have always completed construction on time and within budget. Our tenants have always been extremely happy with their communication, on site supervision and project management deliverables. We continue to count on Black Diamond to partner up with our tenant build outs to ensure a successful project.” 

-Paul LeBeau, Principal LeBeau Realty & Associates

“Black Diamond has been instrumental to the success of our San Diego portfolio. BDC’s teams operates with an ownership mentality as they are always trying to deliver a superior project, at the most efficient price, while delivering the space faster to provide the highest return on the investment.  They have shown they are willing to go the extra step to make sure our customer is happy and comfortable in their new space and create a positive start to a long-term relationship. In closing, our partnership with Black Diamond Construction has created many wins due to the above attributes that we might not have enjoyed.” 

-Phillip Matchett, Director of Commercial Assets, MIG Real Estate

“You guys made it happen with ease! Even with our unforeseen bumps along the way (not to mention Mrs. Beale’s bump), you guys got it done.  We so appreciate your availability when we had questions, changes or requests.  We worked with several groups to make this build out happen, and by far; we can say that Black Diamond was the most professional and easiest part of this process!!!!!” 

-Gael Courtney, Exec. V.P., Flocke and Avoyer

“Black Diamond recently handled the expansion of our La Jolla office by constructing and reconfiguring offices in the new suite.  Their work was absolutely first-rate.  They finished on-time and on-budget.  Even the landlord was amazed at how quickly the project was completed.  Devin & his team were a pleasure to work with and quick to respond to questions.  I could not be happier with their performance.”
