Jason Halpern is the Founder and Managing Partner of JMH Development. Jason Halpern is from a third generation real estate development company with a stellar track record of more than 50 years constructing and managing numerous properties in New York. The Halpern family has built hundreds of residential apartments in Westchester County, NY and New York City, and developed several million square feet of Class A commercial space in Westchester County. With his unique development expertise, Jason’s experience, infused with his vision and foresight, have led JMH in the acquisition and development of several innovative, pioneering properties including several historically significant landmarked buildings.

What differentiates Jason from other developers is his passion and niche for building in historic districts. He builds rapport within the cities in which he builds, and is sensitive to the historic aspects of JMH Development’s historically significant properties. “Respecting the community in which you develop” is a guiding principal for both Jason and his company.

Jason is committed to allotting his personal time and resources to charitable endeavors in his community. He is heavily invested in the Joel A. Halpern Trauma Center at Westchester Medical Center. A Level I Trauma Center, it has the talent and facilities to offer open-heart surgery, complex emergency neurosurgery and orthopedic surgery, as well as the reattachment of severed limbs. The center also cares for burn victims, individuals with multiple life-threatening internal injuries, pregnant women and children, and more.

Jason has also brought his passion for philanthropy to the workplace, enacting charitable initiatives through JMH Development. In 2015, JMH launched an innovative partnership with the global water non-profit charity: water, donating $20,000 of every contract signed at the developer’s Miami-based Three Hundred Collins residential development to fund water projects in Ethiopia and Nepal. Through two of charity: water’s partners on the ground, the Relief Society of Tigray and Splash, JMH Development is bringing clean, safe water to more than 650 Ethiopian and Nepalese locals.

Today, Jason remains involved and dedicated to using his expertise in real estate development to benefit those around him.
