Kenneth DeRiggi

Partner & Project Executive

Kenneth DeRiggi

After being introduced to the industry by his father at the age of 19, Ken Deriggi began his career working in his family-owned architectural millwork company focusing on luxury and single-family residential homes. Without initial interest, his abilities soared but still, he wanted to follow his passion in finance. Ken received his B.S. in Finance at Montclair State University in New Jersey; while expanding the family company into the New York market, growing twenty times greater than it began. Newly inspired, Ken excelled and focused on high-profile opportunities for the next ten years working on some of the most prestigious projects and architects throughout New York City, such-as; The Tribeca Grand Hotel, Covington & Burling Law, The Dalton School, Soho Grand Hotel to name a few in addition to colleges, auditoriums, and trading desk targeting a facet of interior design divisions producing high-quality outcomes. Ken became passionate about turning raw products into mesmerizing final products. He acquired several large-scale warehouses and generated higher income streams through renovation and efficient management to increase net values. It wasn’t until the industry dynamics changed when Ken realized it was time to make his dreams a reality.

In 2001 Ken advanced his career and co-founded CitiStructure, focusing on general contracting, construction management, and real estate development, reintroducing true art and talent back to the construction industry. Clients have included and not limited too, Manatus Development Group, NYC DDC, SLSCO, Cayuga Capital Management, Lend Lease Turner Joint Venture, Metropolitan Lighthouse Charter School, NY Economic Development Corporation, Turner Impact Capital, U.S. Secret Service, Internal Revenue Service, Jacob Javitz Expansion Center, General Service Administration, MetLife, and Housing Preservation and Development. As Partner and Project Executive, Ken brings the skills of interior design, manufacturing, construction, sub-contracting proficiencies, land development, and finance to the team while overseeing day-to-day aspects of the company, including R&D, financial management, and marketing. He directly managed projects such as SoHo Grand Hotel, Metropolitan Lighthouse Charter School, Bethesda Baptist Church Restoration, SkyClub Fitness & Spa, and Luxury Condominiums at 40 East 72nd St. Ken continuously evolve in his expertise from his knowledge of how to build to gain the ability to visualize the whole project. Ken is a problem solver and a visionary with a perpetual focus on growing the business and utilizing resources within his reach. Working with some of the most brilliant architects worldwide with a plethora of knowledge allows him to analyze and value engineer through design projects. He understands the importance of key decision-makers and how a decision at the moment would impact layers of a project and overall business. This mindset is pressed upon many of his employees, giving them the capability to learn daily and use mistakes as lessons on the pathway towards their own success goals.

Today, Ken is inspired by seeing the completion of a project and knowing that major components were developed by his team. In no form does he see construction as an individual task reminding us that “there’s no I in TEAM.” Regardless of being the decision-maker, he encourages his team to feel confident and knowing he’s there to support them. Ken invests in his staff to direct them to the next level. He impresses upon his mentorship and teaching – he loves to teach, loves to challenge, and love to be challenged regardless of status to seek new perspectives. More importantly, he takes time to be a great leader and wants everyone to have the opportunity to be great in their role as he culminates a true power team. A huge incentive for Ken is working with his staff, building trust to lead, and teaching while building – it’s tangible to Ken.

Family is Ken’s top priority; he carefully balances business, home, fun at the golf course, and activities with his son. Ken finds the utmost importance in teaching the value of education and building a strong foundation of respect. Friendship is also greatly valued to Ken; he’s considered a close friend to many and hold relationships to his heart. In the near future, Ken hopes to work with veteran and children organizations. Ken takes pride in hiring people from within developing communities and is an advocator for redefining the position of previously incarcerated people, bringing hope, and helping them see bright futures.

Throughout Ken’s career, he has been striving for greatness and has taken the honor of being an intricate part of CitiStructure’s thriving legacy.
