is the Director of Empresas Rivera Siaca (ERS), a family-owned conglomerate founded in 1974. The primary focus is in the commercial/housing and development of real estate primarily in Puerto Rico along with various other businesses.
Ms. Rivera-Ortiz’s set out over 28 years ago to tackle challenges that were faced by the population of PR. Pinsy’s uncanny ability to see opportunity has brought innovation and creativity to a predominately man ruled island as she was able to successfully bring an impactful result building over 1 million square feet of construction projects. Pinsy possesses the knowledge to compete and the heart to understand the vast challenges that the Puerto Rico real estate market has. She tackles each project with an assertiveness, clarity and with a unique ability to envision what others simply can’t see.
Pinsy, is one of the few women in Puerto Rico in the real estate sector. Ms. Rivera has made a steadfast commitment to carry her father’s legacy, the industrialist and engineer Luis Rivera Siaca and founder of ERS, “to improve the lives of Puerto Rican families and to look out for those less fortunate”. This has led her to incorporate her father’s vision and mission in ambitious projects to create affordable housing to underserved communities with a design that combines empathy and dignity to new homeowners.
In a parallel effort, she has assumed the responsibility for the leasing management, administration, maintenance, and development of the commercial spaces hosting the central administration offices of government agencies with an economic impact in the Island’s local construction sector, design, architecture, materials, and indirect services.
Adding to her diverse professional journey, Ms. Rivera is a turnaround senior executive where she assumed the Presidency of Grana, an iconic Puerto Rican textile company and one of ERS’s portfolio. She transformed the company’s culture and operating structure from a local conservative approach to one with a competitive global vision where profit margin grew from 17% to 32% and then sold the company 2 years later.
Most recently, Pinsy has expanded her love of nature on the premise that economic development and nature preservation can coexist in perfect balance. Her new venture Agro Excel Caribbean, where she serves as the President, is an eco-farm to grow the native Puerto Rican limes. The new farm has surpassed its production goals and is proud of its accomplishment of meeting the local demand of the Puerto Rican community.
Pinsy continues to stay focused on opportunities in and outside Puerto Rico as she searches for projects to exemplify her passion for design, sustainability affordability in both the housing, and eco-farming arena.
Acknowledging the importance of philanthropy, Pinsy serves as part of the Board of CNE (Centro para la Nueva Economía), and since 2019 she has served as the President of the Board of the Ricky Martin Foundation. In addition Pinsy is a member of the Young Presidents Organization (YPO), a prestigious global networking platform for executives.
Pinsy obtained a bachelor’s degree in Food Marketing at Saint Joseph University in Philadelphia, where she later obtained a master’s degree in International Marketing and recently, she completed the Executive Education Program at Harvard Business School. She serves and is an active member of various trade organizations such as the National Association of Home Builders, Puerto Rico Builders Association, Urban Land Institute, and the Puerto Rico Manufacturers Association.
Her biggest accomplishment ever is being the mom to her three college bound sons. Pinsy resides in San Juan, Puerto Rico and travels extensively to industry related events.
