President and Founder

Ryan G. Christiansen, President and Founder, has been a key player in elevating commercial real estate services in Puerto Rico to compete on a global stage for more than a decade. First entering the industry as a commercial brokerage professional in 2004, Christiansen quickly became one of the island’s most sought-after real estate advisors. Striving to establish a new standard of industry excellence, he created Christiansen Commercial Real Estate in 2012 and has since grown the full-service firm into one of Puerto Rico’s leading commercial brokerages.

While success has led to the growth of a talented support team, Christiansen’s passion for brokerage keeps him involved in nearly every transaction that passes through the firm. As one of the island’s leading brokers, he is equipped to handle the needs of both private and institutional investors of office, industrial, retail, land and most all other commercial properties.

With more than $1 billion in gross sales volume, Christiansen brings with him superior market knowledge, deal-making expertise, and influential industry relationships.

In 2019, Christiansen was selected to represent the buyers in a joint acquisition of the island’s largest industrial portfolio. Following the transaction, the new ownership group was in need of a trusted and dependable property management and leasing team for the properties. Once again seeking to raise the industry bar, Christiansen partnered with Hector Del Rio Jr to create Puerto Rico Industrial Solutions Management (PRISM), where he concurrently serves as the Chief Executive Officer.

Ryan G. Christiansen was born in Springfield, Virginia and graduated in 2002 from the University of Dayton with a Bachelor’s degree in International Business. Dedicated to his craft, he went on to earn CCIM designation from the Certified Commercial Investment Member Institute and served as President of the Puerto Rico CCIM Chapter from 2012 to 2014.
