About

Building Exceptional Golf Experiences

GHMG brings together construction, project, and agronomic management expertise built specifically for the golf industry. We've spent our careers on golf properties not adjacent to them which means we understand the operational, financial, and turf realities that generic construction or consulting firms miss.

Whether you're planning a full renovation, building new, or trying to get more out of day-to-day operations, we partner with you from first concept through completion, bringing hands-on experience across both public and private-sector golf.

Meet The Team

Mission

Discipline in the Details

We believe golf projects succeed or fail on the details: realistic budgets grounded in actual site conditions, agronomic plans built around how the course will actually be maintained, and communication that keeps every stakeholder ownership, staff, and community aligned from day one.

Approach

An Advocate for the Owner

Our approach is hands-on by design. We're on site and directly engaged with contractors, consultants, and club leadership, not managing from a spreadsheet three states away. We represent your interests directly vetting decisions, holding contractors accountable, and protecting your investment at every stage.

Why Choose Us

Golf projects demand more than general construction or consulting experience — they demand a team that's lived the details. Here's what sets GHMG apart.

Golf-Specific Expertise

Every project we take on is shaped by golf-specific realities grow-in timing, agronomic sequencing, and seasonal play not retrofitted from general construction experience.

Proven Track Record

Our team's background spans premier private clubs, municipal operations, and large-scale course construction projects delivered on time, on budget, and built to last.

Hands-On, On-Site Leadership

We're on the ground with contractors and superintendents at every stage, working alongside the people actually building and maintaining your course.

Deep Industry Credentials

From agronomy to project management, our experience is grounded in formal training and real-world execution across both public and private-sector golf.

“

As a longtime leader in the Northern California golf community, it is my honor to recommend Gradoville and Hertzing Management Group. GHMG was diligent in assessing the scope of work, collaborated closely with the city's agronomy team, and effectively managed all parties involved. Completed on time and on budget, the result is simply stunning.
