The facility is located on a pleasant six-acre wooded estate in Huntington, Long Island. Hilaire provides around-the-clock care and treatment by registered nurses under the direction of the resident's individual physicians; the community hospital is just a mile away. Physical and occupational therapists, and other specialists, are available as needed. Dental care and podiatry services are performed on the premises.

Meals, taken either in the main dining room or at bedside, are planned by a registered dietitian. An activity program is carried out by personnel trained in therapeutic recreation. Twice-daily activity programs, designed to satisfy a variety of interests, are supplemented by special luncheons and other events. Religious services of all denominations are scheduled as part of the weekly routine.

Visiting is strongly encouraged and made more convenient by a lack of restricted visiting hours. Indoor and outdoor settings provide private and pleasant areas for visits with family and friends. The professional staff is available to meet with family members, and the Social Worker meets with all new residents and their families in order to better understand any particular problems, and to provide ongoing support. All residents will be urged to reach their fullest potential in the areas of emotional and physical health, in an atmosphere which continually offers encouragement and help.
