    I’m so sorry to hear this news. I was a student at St. Anne’s School in Garden City while Sister de la Salle was principal. I remember her fondly. May she rest in peace. My condolences to her family.

    The Cooney family was saddened by the passing of S, Maureen! Richard Lisa and Noelle were students at St. Anne’s Garden City while S. Maureen was principal! Many fond thoughts of her during that time! In the blizzard of 1978 when my sister was operated on for cancer at Sloan Kettering, the RSHM under S. Maureen took care of my three children when I couldn’t get back home! You never forget the people in this life who were so good to you! Rest In Peace S Maureen! You will always be remembered and never forgotten! Thank you. Sincerely, Marie Cooney 🙏❤️

    Parents of three graduates of Marymount Paris, members and once President of the Marymount Paris board and most of all friends of Sister Maureen, we deeply regret her passing but are so profoundly grateful that she was part of our lives. Her intense desire to give the very best to all of the young people who came under her care and their families inspired us all. Patrick & Christine Murray

    Sister Maureen was one of those people who changed lives. She certainly changed ours. She made my husband, Harry, a member of Marymount’s Board; hired me as a Kindergarten aide and then encouraged me to train as a Montessori teacher, resulting in many happy years at Marymount. Our two sons have many memories of Sister Maureen (some of which I only recently discovered!) but she clearly made an impression because Sean very proudly sent his daughter, Chloe, to Marymount while they awaited the birth in Paris of their younger daughter. I will miss her twice yearly “check-in” calls at Christmas and our one-day-apart birthdays. It was said, somewhat humorously, that the two most powerful American women in Paris were Pamela Harriman, US Ambassador at the time, and Sister Maureen who held the keys to Marymount! On a another funny note: whenever you were in the car with her and looking for parking in Paris or Neuilly, Sister Maureen would say “Little Flower, in this hour show your power” and voila there would be the perfect parking space!
    A truly wonderful lady. May she rest in peace.

    We knew Sr Maureen at Marymount Paris, where I was privileged to serve as PTA Board chair under her. She was a special lady who warmly welcomed us all into Marymount. It became our special home while in Paris. My daughters never had better teachers than at Marymount, because of Sr, Maureen’s leadership. She lived life to the fullest and will be remembered fondly by all who knew her,

    sad to hear the passing of Sister Maureen. I was a student at Marymount School in Neuilly/seine from 1981 till 1984. Sister Maurern was an excellent Headmistress and cared for us all. I, then worked at Marymount from 1990/1991 as an Aide Maternelle teacher. They were good memories and enjoyed those years. Sister Maureen will be dearly missed

    I am so grateful that during Sr Maureen’s time in Rome I was able to once again spend time with her. We had a joyful and reminiscing dinner along with several of the other sisters at Marymount Rome. I met Sr Maureen when she hired me as a curriculum consultant in Paris, but later, I became chair of her board. I was chair during the time of EuroDisney’s beginning in Paris and we had many children from the Disney families. It was an exciting time, and she was an inspiration. I can only imagine the number of lives she touched during her lifetime. She was compassionate and smart, and fun.

    So sorry to hear of Sr. Maureen’s passing. Our daughters spent 4 years at Marymount in Paris. We were extremely grateful that the girls had this experience. Our sincere condolences to all affected by her passing. She was an inspirational leader of the school and will be remembered fondly forever.

    The best boss that I ever had in my working career.
    In my opinion, the Marymount School in Paris was at its best when Sr. Maureen was at the helm.
    The amount of respect to her from the students, teachers, parents and international people was amazing but not surprising. A very intelligent person with a good sense of humor.
