William “Billy” O’Neil

William “Billy” O’Neil is the Co-President and Owner of MC3 Solutions, LLC, a Service-Disabled Veteran-Owned Small Business focused on government construction, project management, and mission-critical infrastructure execution.

Billy brings a rare combination of special operations leadership, business operations, and acquisition-focused management experience. Prior to entering the private sector, he served 14 years in the United States Marine Corps as a Scout Sniper, Scout Sniper Instructor, and Marine Raider with Marine Forces Special Operations Command. His military career included five combat deployments to the Middle East, where he led specialized teams in combat operations, coordinated complex logistics, and operated in high-risk environments requiring disciplined execution, sound judgment, and accountability. He demonstrated leadership across 50+ combat missions in Iraq and hundreds more in Afghanistan, oversight of $20 million in equipment supporting Special Operations Marines, and management of 36+ foreign contractors on a $250,000 base-expansion effort that increased operational and defensive capabilities by 400%, all while continuing combat operations.

After transitioning from the Marine Corps, Billy built a business career centered on operational improvement, growth, and organizational execution. As an Operating Partner Intern with Windjammer Capital Investors, he supported operational improvement initiatives. In that role, he helped streamline legacy processes at a business services portfolio company, reducing merchandise picking time by 75%, and served as project lead for the relocation of more than 15,000 SKUs to a new facility approximately 800 miles away, completing the transition three weeks ahead of schedule.

Billy later served as Chief Operating Officer of Burch Barrel, an outdoor retail business in the Philadelphia area. In that role, he led strategic growth and operational turnaround initiatives, including building a new marketing and sales function, implementing a wholesale pricing and outreach system that drove a 100% increase in sales flows and a 230% increase in wholesale distributors, reducing overall company expenses by approximately 50% through contract renegotiation and cost controls, and installing an EOS operating cadence to improve communication, accountability, and culture. Separate background materials note that under his operational leadership, the company became profitable for the first time in two years within approximately three months.

Billy holds a Master of Business Administration from The Wharton School of the University of Pennsylvania, where he served as Co-President of both the ETA Club and the Veterans Club. He also earned a Master of Science in Organizational Leadership from Norwich University and a Bachelor of Science in Strategic Studies and Defensive Analysis from Norwich University, graduating summa cum laude. He currently has one semester left to complete a Master in Public Leadership from the University of San Francisco.

At MC3 Solutions, Billy applies his background in special operations, private equity operations, and business turnaround execution to help lead a growing SDVOSB construction platform. He focuses on disciplined growth, operational accountability, team development, project execution, and building durable systems that let the company scale without sacrificing quality, compliance, or financial control.
