About Us

Designing and Building Better, Together Since 2004

G.M. Hill Engineering, Inc. (GMHILL) is a dynamic, woman-owned small business founded in 2004 and headquartered in Jacksonville, Florida. With a bold vision from our founder, Gina M. Hill – an experienced structural engineer with over 25 years of expertise – GMHILL has grown from a one-woman operation into a powerhouse team of nearly 80 professionals. We’ve evolved from our roots in structural engineering into a full-service architecture, engineering, and construction firm, delivering innovative, integrated solutions nationwide. At GMHILL, we believe in pushing boundaries. Our team of experts brings creative, cutting-edge approaches to each project, delivering seamless results from concept to completion. Whether it's a high school renovation, a new working dog kennel, laboratory renovation, or shoreline stabilization, we thrive on tackling challenges across all sectors, including government, healthcare, education, and commercial. Our hands-on commitment to service, innovation, and quality has earned us a reputation for delivering projects on time and within budget – every time.

Integrating Excellence

We don’t just design; we build. As one of the few firms offering bonded, at-risk design-build services, we blend the best of architecture, engineering, and construction under one roof. This integrated approach allows us to execute complex structural analyses, feasibility studies, facility assessments, master planning, sustainable design, construction management, and beyond. Our latest design and drafting software ensure we stay ahead of the curve, offering unparalleled precision and efficiency.

With a bonding capacity of $20M single and $70M aggregate, we are equipped to handle large-scale, multi-phase projects, and simultaneous endeavors. From intricate federal contracts to large private developments, our work is driven by a mission to build smarter, faster, and better for our clients. Our portfolio includes successful collaborations with agencies like USACE, USAF, NAVFAC, USDA, FWC, Duval County Public Schools, and more, bringing groundbreaking solutions to life across the nation.

Our track record speaks for itself. In recognition of our excellence, GMHILL was honored with the 2023 SAME Small Business of the Year and the 2024 SBA Florida Woman-Owned Small Business of the Year. As we look to the future, we remain focused on creating forward-thinking solutions that meet the needs of today and tomorrow. At GMHILL, we’re not just building structures – we’re building legacies.
