Iconic attraction and new development to accelerate demand for local healthcare services

NATIONAL HARBOR, MD / ACCESS Newswire / April 29, 2026 / National Harbor continues to grow as a major mixed-use destination with the announcement of a new Sphere entertainment venue, which will be the facility of its type in the U.S.

Solidifying the area's status as a premier regional destination, the high-profile project is expected to bring increased foot traffic, residential growth, and economic activity, driving demand across the area and creating new opportunities for medical practices located nearby.

As activity and investment increase, Medical Pavilion I & II at National Harbor, owned by Rethink Healthcare Real Estate, is well-positioned to serve a growing population of residents, workers, and visitors seeking convenient outpatient care.

"You don't see an entertainment project like the Sphere land in a market unless there's long-term confidence in the location," said Peter Papantoniou, principal at Gittleson Zuppas Papantoniou Medical Realty, leasing broker for Medical Pavilion I & II at National Harbor. "For healthcare providers, that kind of momentum matters. It signals a growing, active community where accessibility, visibility, and patient demand are only going to increase and where available high-quality space is becoming increasingly limited."

The National Harbor Sphere, a 6,000-seat, smaller version of the globally recognized Las Vegas venue, will deliver immersive entertainment experiences to the waterfront district, complementing National Harbor's existing mix of retail, dining, residential, office, and hospitality offerings.

In addition, the Prince George's County Planning Board recently advanced a $720 million mixed-use development plan located near Medical Pavilion I & II. The project includes more than 1,000 market-rate multifamily units, 485 affordable senior apartments, as well as new retail and office space, further expanding the population base that Medical Pavilion I & II is positioned to support.

"Developments like the Sphere and the recently advanced mixed-use projects nearby reinforce why we invested in National Harbor," said Malika Peltier, Managing Director of Asset Management for Rethink Healthcare Real Estate. "Medical Pavilion I & II was designed to support long-term growth, offering healthcare providers a platform to establish and expand within a dynamic, evolving community."

Medical Pavilion I & II at National Harbor is uniquely positioned to meet the area's expanding healthcare needs. The property offers approximately 190,000 rentable square feet of Class A outpatient medical space in a walkable, waterfront environment with convenient access to surrounding residential communities, retail amenities, and public transportation.

Located just eight miles from downtown Washington, D.C., the property provides an attractive opportunity for medical practices and healthcare systems seeking to grow within an expanding, mixed-use setting. With leasing activity increasing alongside new development in the district, a limited number of spaces remain available for providers seeking to establish or expand their presence at National Harbor.
