The Bell Mare at River Road to Offer Luxury Senior Living in the Metro DC Area

Opening in Fall 2028, the 94-unit community will offer senior living — assisted living and memory care.

POTOMAC, Md., Nov. 10, 2026 /PRNewswire/ -- The Bell Mare at River Road will bring a modern, upscale senior living community to a 5.93-acre site in Potomac, one of Maryland's most desirable suburbs. Twenty-four percent of Montgomery County residents are age 60+, a population projected to grow nearly four times faster than younger age groups. Nationwide, the 75+ population is expected to grow nearly ten times faster than the rest of the country over the next five years, signaling a growing need for senior living options.

Slated to open in Fall 2028, The Bell Mare at River Road will offer 68 assisted living residences and 26 memory care residences, with studio, one- and two-bedroom options ranging up to 1,554 square feet. Apartment homes will include granite countertops, walk-in showers, private patios or balconies and in-unit laundry.

Designed by Vessel Architecture and Rodrigo Vargas Design, the two-story community will feature refined masonry, structured trellises, shaded patios, tree-lined views and expansive windows.

AARP ranked Montgomery County the second-best place to live for older adults among U.S. communities with populations of 500,000 or more, making Potomac an ideal senior living location for developer Harbert South Bay Partners and management company Momentum Senior Living.

"Our approach has always been to create senior living communities connected to the places and people they serve," said Zac McCullock, Director of Development & Construction at Harbert South Bay Partners. "Potomac is an opportunity to bring our upscale senior living expertise and create a community that reflects the area's lifestyle, distinctive character and commitment to a high quality of life."

Isolation is one of the most commonly identified concerns among Montgomery County's older adults, making social connection a key priority for The Bell Mare at River Road.

"Senior living can help older adults stay connected to the community around them," said Josh Johnson, CEO of Momentum Senior Living. "The Bell Mare at River Road will combine exceptional amenities with a holistic approach to daily living, creating a place where seniors can build meaningful friendships and find a sense of belonging."

Elevated amenities, including a movie theater, game rooms, a pet park, beauty salon, library, chapel, indoor pool, fitness center, bistro and coffee bar, will support an active and enriching lifestyle. Located 20 minutes from downtown Bethesda and 30 minutes from Washington, D.C., the prominent River Road property offers convenient access to top-tier healthcare, shopping and cultural experiences.

The media is invited to attend a groundbreaking ceremony for The Bell Mare at River Road at 9:30 a.m. on Tuesday, Nov. 17, at 9545 River Road, Potomac, MD 20854. Speakers will include: Zac McCullock of Harbert South Bay Partners, Gilbert Carrasco of Momentum Senior Living, Todd Donze of Vessell Architecture and others.

The leasing office will open in Summer 2027, with occupancy beginning in Fall 2028. For the latest construction updates or more information about the community, please contact 214.370.2627
