Meet The Family

Meet the people behind YBL Design & Build. As a family-run company, we take a hands-on approach to every project and value clear communication, organization, and quality execution from start to finish.

Isaac Efraim

Owner

Isaac leads YBL Design & Build with a hands-on approach shaped by both construction experience and a strong background in project management. After graduating and spending three years at Blackstone, he returned to grow his family’s construction business with a more organized, client-focused approach.
As a former Division I athlete, Isaac brings discipline, focus, and a strong sense of accountability to the way he manages each project. He is deeply involved from the early planning stages through construction, with an emphasis on clear communication, attention to detail, and a well-managed client experience.
His goal is not only to deliver a beautiful finished result, but to make the process feel structured, transparent, and professionally handled from start to finish.
