A Humble Consultant: Master Builder, Trusted Advisor, Relentless Learner
I am not just a consultant—I am a builder at heart. With over 30 years of experience spanning architecture, development, and construction, my career has been a relentless pursuit of understanding how things come together—whether it’s a structure, a business, or a life of purpose.
I started my journey as an apprentice to my father, a semi-successful general contractor, where I first saw the raw beauty and brutal challenges of the trades. From vocational high school drafting tables to earning an architecture degree, from designing buildings to running multi-million-dollar real estate developments, I’ve lived every facet of the AEC industry. I’ve been an architect obsessed with buildability, a developer balancing vision and viability, and a contractor navigating the realities of construction.
I’ve worked in the trenches, sketched ideas that turned into thriving spaces, and led projects that transformed communities. Through recessions, reinventions, and relentless learning, I’ve come to embrace a philosophy I call The Tao of the Unfinished Masterpiece—the understanding that mastery is never complete, and the best builders never stop refining their craft.
The Perspective That Sets Me Apart
Most consultants offer theories; I offer lived experience. I’ve stood where my clients stand—making payroll, chasing payments, negotiating with GCs, and managing the chaos of construction. I know the pressure of balancing cash flow while trying to grow a business. I know the frustration of being treated as a commodity when you should be valued as a trade partner.
I don’t just advise—I teach, coach, and build systems that work in the real world. My approach is grounded in humility and radical pragmatism—no fluff, no corporate jargon, just actionable strategies that create tangible results.
​
Who I Serve & Why
I work with general contractors, subcontractors, architects, and non-profit developers who are ready to break through limiting patterns and build thriving, resilient businesses. I help subcontractors shift from being just another vendor to an indispensable trade partner. I guide design firms in bridging the gap between vision and execution. I assist contractors in streamlining operations, fixing cash flow problems, and securing the right projects. I support non-profit developers in balancing mission and financial sustainability.
More than anything, I help my clients build a business—and a life—they don’t need a vacation from.
