About - Hans Middelberg
A Life of Innovation, Adventure and Purpose
​
A lifelong entrepreneur whose story spans continents, industries, and passions. Born and educated in Germany, Hans began his career as a structural engineer, contributing to the design of early bridge systems—a foundation that would support a lifetime of visionary pursuits.
​
His journey quickly expanded beyond the drafting table. Hans launched a successful aircraft trade business, delivering products in small planes across borders with precision and ingenuity. This chapter was followed by a deep dive into equestrian interests, a reflection of his disciplined yet adventurous spirit.
​
After relocating to the United States, Hans turned his engineering expertise toward the revitalization of urban properties, restoring buildings in some of New York’s most challenged neighborhoods.
These early efforts opened the door to a flourishing career in commercial real estate—particularly in the highly specialized domain of medical facilities, where he managed not just construction, but the intricate web of installations, negotiations, and leasing.
​
His success in this sector naturally evolved into the development of high-end properties in Greenwich, Connecticut, where luxury met function in every project he touched.
​
His personal passions were just as dynamic. He brought rare vintage cars back to life with his own hands—Some that would go on to compete in some of the most grueling road rally events across the globe. For 30-day expeditions with only a road book and a machine, he pushed the boundaries of what adventure and endurance could look like.
​
Among his many avid sports hobbies included skiing. Hang gliding and Hot-air ballooning. His love of extreme sports was never for spectacle—it was a pursuit of challenge, focus, and freedom.
​
Now, he stands at a new threshold—not of conquest, but of contribution. With decades of experience across engineering, real estate, restoration, and sport, he is ready to pass the baton. Through this site, Hans offers his wisdom, guidance, and mentorship to the next generation of innovators, adventurers, and builders.
