Beyond RSZ Design + Development, Rosa expands her impact through Build with Rosa, a dynamic lifestyle brand that blends design, construction, and storytelling. Through her YouTube channel, social media platforms, and bilingual children’s book—Rosita’s Design Adventures – Las Aventuras de Diseño de Rosita, she makes design fun, accessible, and inspiring for all ages.

In her talks, Rosa loves to blend humor, vulnerability, and hard-earned wisdom from 28 years in design and construction to empower women to embrace authenticity, lead with impact, and choose intention over perfection.

 

Whether leading high-end design projects, mentoring the next generation, sharing her expertise with bilingual audiences, or inspiring listeners through speaking engagements, Rosa’s mission remains the same: to inspire, uplift, and prove that with passion and perseverance, anything is possible.
