ARMONK, NY, July 30, 2026 /24-7PressRelease/ -- Joseph D. Mastromonaco has been selected for inclusion in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.

Marked by over five decades of progressive leadership and operational expertise, Mr. Mastromonaco has led a distinguished career in the electrical industry. Since 2000, he has served as co-president and board member of JDC Power Systems, a company he co-founded in Manhattan, New York, and has guided for over 26 years. In this capacity, he managed daily operations from an executive perspective, oversaw corporate sales and vendor management and maintained direct engagement with customers to complement the presence of a dedicated sales department. His stewardship has been pivotal in shaping the company's mission to provide its data center partners with individualized design, training and servicing electrical solutions.

A defining milestone in Mr. Mastromonaco's tenure at JDC occurred in 2024, when he and his founding partner executed a private equity agreement that enabled them to position the organization for aggressive expansion, resulting in significant growth. JDC Power Systems earned the Great Place to Work Certified USA distinction from the Great Place to Work Institute for 2025 to 2026, reflecting his company's commitment to fostering a supportive and team-centered workplace culture.

Central to Mr. Mastromonaco's legacy is his dedication to leading with integrity and building trust, both with clients and employees. He emphasizes that securing multimillion-dollar contracts depends on clients' confidence in the company's integrity and ability to deliver on commitments. This philosophy extends internally; he has prioritized hiring experienced professionals, particularly those who joined in recent years with two decades or more of industry know-how.

Notably, about 18% of JDC's workforce is comprised of military veterans who are supported by an on-site training center designed to bridge technical gaps and facilitate their transition into specialized roles. The company's "We Made the Employer Pledge" emblem underscores this ongoing commitment to veteran employment and development.

Prior to founding JDC Power Systems, Mr. Mastromonaco spent 20 years as chief operating officer at an electrical wholesaler, honing his skills in managing business operations and driving sales growth across the electrical supply chain. He began his foundational professional experience in 1969 as a field electrician at age 15 — a path influenced by his father's insistence on learning a trade through hands-on work rather than solely academic study. Throughout his college years, he worked as both an electrical contractor and electrician, laying the groundwork for his lifelong commitment to the electrical field.

Today, Mr. Mastromonaco is widely recognized for his expertise in corporate operations, management and sales — skills that have been critical to his sustained success and industry prominence. Alongside his primary work at JDC, he is an active member of professional organizations such as 7x24 Exchange and DCD, keeping himself connected to evolving trends and best practices within the sector.

Happily married and the proud father of three children, Mr. Mastromonaco enjoys playing golf as well as buying, selling and renting real estate properties — a pursuit where he once applied his construction skills but now focuses on investment rather than physical renovation. He is also a grandfather to seven granddaughters with whom he cherishes spending time together.

Looking toward the future, Mr. Mastromonaco remains committed to ensuring that JDC Power Systems continues as a stable and financially robust organization for its employees following any future changes in ownership structure. He believes that true accountability comes from treating business not merely as a financial venture but as a personal passion — one where every decision carries weight for employees' livelihoods, families and long-term security.
