THE PARENT+DIAMOND STORY

Ralph Parent and Merrill Diamond share a personal relationship built on more than 30 years of trust and collaboration. Their connection began when Diamond coached Parent in Little League baseball, and over time evolved into a long-standing professional relationship. Throughout Parent’s career growth, Diamond has been a trusted advisor and colleague, creating a foundation of respect that now defines their business partnership.

Following the retirement of Merrill Diamond’s longtime partner at Diamond Sinacori, the two saw an opportunity to combine their complementary strengths and rebrand the firm as PARENT+DIAMOND, LLC. Together, they continue the company’s legacy of socially responsible development in both the private and public sectors.

Both Parent and Diamond bring extensive real estate experience and share responsibility for all aspects of the firm’s work, from deal negotiations and securing financing to overseeing development and guiding projects to completion. Each also contributes individual strengths that enhance the firm’s capabilities. Parent has a particular focus on entitlement and market positioning, ensuring projects move smoothly from approvals through sales. Diamond contributes deep expertise in development strategy and execution, building on decades of successful projects. Together, their collaboration ensures that every project benefits from a full range of skills and perspectives.
