Inspired by Baja. Shaped by Experience.

    CONTIGO BAJA

    Contigo Baja was founded by husband-and-wife team Karina Christensen and Ron Sprengeler with a shared vision: to create boutique homes that feel deeply connected to their surroundings. Drawn to Baja not just for its beauty, but for its rhythm of life, Karina and Ron believe that great design should enhance the land, not compete with it.

    Their work is guided by intention—blending thoughtful architecture, restrained luxury, and a deep respect for the natural environment. Each project is conceived as a place to truly live, where design feels grounded, the landscape is honored, and homes are created to endure—both in spirit and in time.

    CONTIGO CERRITOS

    Contigo Cerritos™ is a reflection of our deep respect for the natural beauty of Baja and our belief in the transformative power of living well within a thoughtfully curated community. Set in a remarkable coastal landscape, our project is designed to feel both expansive and intimate—where open space, privacy, and connection coexist with ease.

    Here, luxury is expressed through balance. Homes are carefully integrated into the land, allowing nature to remain present and uninterrupted, while the community itself is shaped to foster a sense of belonging without sacrificing independence. Contigo Cerritos™ offers a holistic way of living—one that feels grounded, restorative, and deeply connected to place.

Meet the Team

  • Community-Builder

    Karina Christensen brings more than two decades of experience to Contigo Cerritos™, shaped by a career rooted in design, development, and relationship-driven real estate. Her work spans residential development, luxury sales, and long-term brand building, including ownership roles within Keller Williams Realty franchises and leadership of an exclusive residential team serving high-end clients from Denver and Aspen to Baja California Sur.

    With formal training from the Parsons School of Design, Karina’s foundation in design deeply informs her approach to space, flow, and livability. Earlier in her career, she designed and managed private jet interiors—an experience that led her to work closely with Oprah Winfrey as part of her personal flight team, where precision, discretion, and thoughtful detail were paramount.

    Today, Karina’s focus is on creating places that feel intentional, grounded, and enduring—communities where design enhances daily life and connection comes naturally. At Contigo Cerritos™, her role as a community-builder is less about scale and more about care: building places that belong to their setting and to the people who choose to live there.

  • Project Management & Construction Oversight

    Ron Sprengeler brings more than three decades of experience overseeing complex construction, safety, and operations projects at the highest level. His background includes managing large-scale initiatives for a Fortune 25 oil and gas company—work that demanded precision, accountability, and a deep respect for process.

    At Contigo Cerritos™, Ron serves as the steady hand behind the scenes, guiding development and construction with care, discipline, and an uncompromising attention to detail. His approach is grounded and methodical, ensuring that every phase of the project is executed thoughtfully, responsibly, and to exacting standards.

    Ron’s role is not just about building structures, but about stewarding quality—from the integrity of the build to the long-term experience of those who will live there. His commitment to craftsmanship and safety helps ensure that Contigo Cerritos™ is not only beautifully designed, but enduringly well built.
