CORE Commitment to Excellence.

CORE Beginnings.

With over 20 years of hands-on experience in the construction industry, I’ve built my career on a foundation of technical expertise, strategic leadership, and an unwavering commitment to exceptional customer service.

My journey began in the trades, where I developed a deep understanding of quality craftsmanship and attention to detail. Over the years, I advanced into account management and senior leadership roles, serving as Director of a transportation company and successfully opening and managing a large company branch in Southern California. Most recently, I held the position of Chief Operating Officer at a design build construction company, where I refined my ability to deliver outstanding results for discerning clients who expect nothing but the best.

These experiences taught me that true excellence in construction goes far beyond technical skill—it’s about listening to clients, anticipating their needs, and executing every project with precision, integrity, and care. Driven by this belief and a passion for raising the standard of service in the industry, I founded Core Build Group, Inc. and Core Paintworks.

Today, through Core Build Group and Core Paintworks, I bring the highest level of professionalism, unparalleled attention to detail, and personalized customer experience to clients across both Northern and Southern California. Whether it’s a commercial, complex build, a luxury remodel, or premium painting and finishing work, my team and I are committed to delivering results that exceed expectations—every time.

I look forward to the opportunity to partner with you on your next project and to create spaces that truly reflect your vision.
