Michael G. O’Mara is a senior executive, entrepreneur, and strategic advisor whose career of more than two decades spans the ownership, operation, and transformation of businesses across the United States and Mexico. His professional life has been defined by a recurring challenge — entering organizations at critical inflection points and leaving them structurally stronger, more profitable, and better governed than he found them. His formation as an operator began in the mid-1990s as President and equity holder of JSC Corp., a Connecticut-based mechanical contractor employing more than 200 people, which he recovered from multi-year losses and positioned for a successful sale to a public utility in 1997. That experience gave way to a four-year run as Managing Partner of Acquisitions Management Group in Houston — a boutique M&A practice focused on the HVAC, mechanical, and electrical contracting sectors — where he represented more than 40 companies and conducted formal valuations of more than 200 businesses. In 2004, he joined Quanta Services (NYSE: PWR) as a Vice President of Operations, overseeing a 140 million P&L and executing a landmark California subsidiary turnaround — from an 8% operating loss to a 14% operating profit.
Beginning in 2012, O’Mara co-founded and led Meridian Energy Group, LLC, and its Mexican operating entity, Meridian Energy Solutions S. de R.L. de C.V., operating out of Mexico City and Monterrey. He built a cross-border energy services company delivering engineered conservation measures — lighting, HVAC, refrigeration, and building controls — to large commercial and institutional clients across Mexico. Concurrently, from 2007 to 2025, he served as Chief Financial Officer of Gemstone, LLC, a Florida-based national bridge and structural coatings contractor, where he helped build the company’s financial infrastructure — installing accounting controls, cash management systems, and the company’s first surety line of credit — driving approximately 90% of projects to gross margins exceeding 30% and creating the conditions for a successful company sale in June 2023.
Since 2021, O’Mara has served as Director of Business Strategy at Alvarez Plumbing & Air Conditioning, a 50-year-old, 3rd generation, Tampa-based home and building services enterprise, delivering consecutive annual revenue growth exceeding 19% while lifting net profitability above 5% and expanding the workforce by 58%.
O’Mara holds a Master of Science in Business Administration from the University of South Florida and a Bachelor of Science in Business Administration from the University of Louisville. He has been a recognized speaker on organizational growth, data-driven management, and contractor finance across Tampa Bay’s business and civic community.
Behind Michael O’Mara’s approach to institutions, governance, and leadership lies a family heritage that reaches to the earliest foundations of the American republic. He is a fifth great-nephew of James Madison — principal architect of the United States Constitution, co-author of The Federalist Papers, and the fourth President of the United States — whose enduring conviction that free societies require carefully designed institutions, checked power, and written codifications of rights has shaped O’Mara’s own philosophy of leadership: that durable organizations, like durable republics, are built on structure, discipline, and the deliberate development of systems that outlast any individual.
O’Mara serves as the personal custodian of a remarkable collection of Madison family artifacts, including the President’s pocket watch (c. 1812), Madison’s Presidential decanter, and several original Madison documents. Most notably, he has served as steward of Madison’s personal copy of the Declaration of Independence, recently entrusting its future care and management to David Rubenstein — the prominent historical philanthropist and co-founder of The Carlyle Group — whose lifelong commitment to preserving America’s founding documents ensures that this singular artifact will endure for generations to come.
