Transforming Underperforming Office Assets
into High Value Investments since 1991
“Over the course of my 30-year career, I’ve had the good fortune of executing over $4.95 billion in institutional-quality real estate transactions across more than 200 assignments. Throughout that time, I’ve worked with some of the most sophisticated sponsors in the business—and Dave stands out as one of the most creative and financially disciplined among them. Dave has a rare talent for optimizing commercial real estate in the built environment—balancing bold vision with investor-focused precision. He’s not only a capable operator; he’s a thoughtful, forward-looking partner I would endorse without hesitation.”

"Our firm negotiated a long-term extension and relocation deal with David and his team. David was pragmatic, attentive, and quick to meet in-person to discuss and resolve issues when needed."

"I’ve known Dave for over ten years and have worked with him on many commercial projects in the Phoenix Metro area. Dave elevated the design of any space we collaborated on. He has always understood the value of a well-designed interior space, and how that impacts the people who work in that space."

"Stevens Leinweber Construction has worked with Dave Warren for almost 20 years. I can honestly say I have never worked with a better developer in the Phoenix area. Dave, himself is highly involved in all aspects of his projects and is always reachable and open to discussing any issues that may arise. Good communication is important to the making of a successful project and Dave certainly has the skills required to make any project successful."

Project Manager; Stevens Leinweber Construction
"As an office leasing broker, I’ve had the opportunity to represent Dave on many of his commercial property ventures. Dave utilizes a thoughtful approach and understands the risks and complexities that are inherent with high stakes real estate investments. This includes implementing creative solutions to various aspects of real estate investing such as design and construction decisions, leasing challenges, and financial considerations. Importantly, Dave is persistent which reflects his commitment to ensuring a successful outcome for stakeholders in his ventures. It’s been a privilege to have Dave as a client over the years."
