HDC is entering an exciting new chapter. 🏗️

For more than 30 years, John Harmon’s leadership has shaped HDC into the company it is today. Built on quality, integrity, strong relationships, and an unwavering commitment to our clients and team.

As we honor that incredible legacy, we’re proud to announce the next generation of HDC leadership: Kristen Mills as President and Nick Mills as Principal and co-owner.

Kristen and Nick bring a deep connection to HDC, tremendous respect for its history and team, and a shared vision for its future, including an exciting path forward as a woman-owned business.

Leadership may be evolving, but the values and relationships at the heart of HDC remain the same.

We’re incredibly grateful to John for the foundation he built and the culture he created. Now, we look forward to building on that legacy, strengthening the relationships that have made HDC successful, and creating new opportunities for the future.

Here’s to the next chapter of HDC. ❤️

Labor Day is a reminder that every successful project is built by people. Owners, designers, contractors, trades and consultants working toward a shared goal. HDC helps owners create alignment across that entire team while protecting budget, schedule, quality and project priorities.

Excitement is brewing at The Maryland Zoo in Baltimore! We can’t wait to welcome the Red Pandas next year.

RED PANDA UPDATE: A new building is taking shape between the future red panda yards! This space will give our amazing animal keepers the room they need for daily care and operations, while also providing separate indoor areas for the red pandas. 🐾
