David Olson
General Contractor, Principal
I was born and raised on the vibrant westside of Los Angeles, where I developed a passion for competition, teamwork and dedication to service greater than myself. During my time at Loyola High School, I had the privilege of not only playing on championship varsity football and volleyball teams, but volunteering for various school & community causes; experiences that taught me the value of commitment, perseverance, and humility.
I continued my academic and athletic journey at Harvard College, where I earned my degree with Magna Cum Laude honors while lettering on the varsity volleyball team. After graduating, I began my professional career in commercial real estate development at Majestic Realty Co. in City of Industry, CA. There, I served as a Development Partner and Director of Capital Markets, gaining invaluable experience in the world of construction management, capital markets, development and real estate.
My path then took me up north to San Francisco, where I founded the development arm at West Valley Properties, further honing my skills in the development sector.
For the past 15 years, I have ventured out on my own as a residential real estate investor and licensed broker, developer, and general contractor. My specialty lies in custom residential remodels and ground-up developments from concept design, architectural and engineering, through entitlement, permit processing and general contracting / building.
My success is a direct product of the expertise I’ve refined from the wide range of experiences earned in real estate, design, general contracting and construction. It is amplified by my proven ability to combine structure, organization, vision, and construction knowledge seamlessly with well-developed project management skills and leadership qualities through every phase of the construction process. I am devoted to creating meticulously crafted, thoughtful spaces that enhance and enliven those who inhabit them.
Thank you for taking the time to learn more about me. I look forward to connecting with you and working together to bring your project visions to life.
