Charlestown in Catonsville, MD, delivers three levels of residential care—Assisted Living, Independent Living, and Memory Care—allowing residents to transition without leaving the community. Clinical capabilities include monitoring residents who are up all night, administering oxygen, supporting special diets, and managing diabetes by oral medication, injections, or sliding-scale insulin. The Memory Care neighborhood is structured for individuals with moderate dementia, combining secure surroundings with the same medical resources available elsewhere on campus.

Registered nurses or licensed practical nurses are on site around the clock, backed by an on-call nurse for added coverage. All employees undergo background checks, and the building is staffed by awake night-shift personnel as well as an asleep shift for added redundancy. Rooms are equipped with door alarms and pull cords that either alert staff directly or connect to 911 through the PERS system. An activity director coordinates daily programs, and 24-hour security safeguards every entrance. For personal care, staff can assist with bathing, eating, and dressing when only some physical help is required; full assistance is available for toileting. Transfer support ranges from standby supervision to one-person transfers with walkers or wheelchairs.

Residences vary by size and layout, and not every unit offers every feature. Options can include a private bathroom, kitchenette, furnished living spaces, independent temperature controls, cable service, and the ability to paint or decorate. Some apartments have in-unit laundry, while others rely on scheduled community laundry services. Housekeeping is included for residents who need it, and those in Independent Living can opt for periodic housekeeping on a preset schedule.

Dining service provides both set menus and on-order meals, with snacks always available and the option for in-room dining or a private dining room for family gatherings. The culinary team accommodates diet modifications such as gluten-free, vegetarian, mechanical-chop, purée, and thickened-liquid textures. Independent Living residents may choose a monthly meal plan and can receive medication-management monitoring if desired; they can also add housekeeping and laundry services on an as-needed basis.

Amenities on campus include wheelchair-accessible paths, a barber and beauty shop, exercise room, movie room, wellness center, internet access, communal gardens, on-site religious services, a concierge desk, library, and scheduled transportation for shopping or medical appointments.
