About Us

Our small family of senior caregivers and operators in the Greater New Orleans area including Metairie, Lakeview, and Jefferson, have over thirty years of healthcare and senior living experience including nursing home and assisted living administration, home health and hospice management, nursing care and nurse education.   It is our collective experience and the feedback from those we have served that has motivated us to offer our alternative to traditional senior living facilities. Frequently, senior living facilities use words like ‘homelike’ in marketing materials to convey a more appealing setting, but even when done well, traditional models cannot escape the institutional feel. A true family home offers what large operations can only hope to emulate. The Peristyle Residences team of professional senior caregivers includes a Registered Nurse who serves as our Wellness Coordinator, an RN who manages Medication Administration, Music Therapy Department, an Program Director, and each home is served by a dedicated House Manager and a caring team of CNAs. 

If you are interested in our residential assisted living and memory care services please schedule a tour or contact us for more information.
