Ryan McCarthy, Our Founder

Ryan McCarthy, founder of GC Builders, began his career in residential construction while in college and went on to take on many roles across the industry—framing, supervision, project management, budgeting, and full project coordination. That range of experience gives him a practical, ground-up understanding of how great homes are built.
‍
Ryan is a builder at his core. He stays closely involved in every major step of each project, working directly with architects, designers, subcontractors, and clients to maintain clarity, precision, and consistently high standards. He built GC Builders the same way he builds homes: with discipline, craftsmanship, and a commitment to strong relationships—earning repeat clients, referrals, and a reputation for thoughtful, high-quality work across Greater Boston.
