Her main focus has been in Adult Lay Faith Formation. She has worked for the Archdiocese of Westminster, for the Archdiocese of Kingston, Jamaica and now at the Niland Centre. She loves to search the Scriptures with people, and to see them grow in their faith and realize the richness of the Christian message.  This is also true of her working with Extraordinary Ministers of Holy Communion which is a great source of joy and opportunity for growth .

Monika Cleaver

Monika is a lay person, married with 3 children and 6 grandchildren.  She has been connected to the Dominican Sisters for over 30 years and enjoyed many events at the Niland Centre. She is an Associate of the Congregation and is part of the Leadership Committee for the programme.  Sr Regina asked Monika to join her work as a speaker after she completed her theology studies at Heythrop College.  They have presented reflections together at the Niland Centre since 2014.  Monika is also very engaged in her parish, as RCIA lead catechist, bringing Holy Communion to housebound parishioners, and organising tea parties for lonely elderly people.  Monika’s passion lies in sharing her faith with adults of any age.   


Ausra Cane

Ausra works in Adult Faith Formation at the Agency for Evangelisation of Westminster Diocese, taking responsibility for short courses, small groups among many other tasks. She teaches at the Open University and the Maryvale Institute, and contributes to the formation programme for permanent deacons in Scotland. Ausra’s collaboration with the Niland Centre began providentially in 2014, and together we have created a programme of formation for parish lay ministers of Holy Communion and the Word that is offered in the Centre, Vaughan House and in a variety of parishes across the Diocese.


The vision of the Sisters was, and remains, to use the Centre as a foundation for preaching and teaching the Gospel, the Good News of Jesus Christ, in our time and society. Nearly twenty years on, this remains our priority. The Niland Centre is still administered and run by the Dominican Sisters to promote and support Christian Spirituality, Education and Formation.

A mainstay of our ministry in the Centre is hospitality—welcoming groups from various walks of life, of different faiths and no faiths, and providing them with space and facilities for their various types of meetings.

Perhaps the greatest treasure we offer is tranquility–a tranquility that comes from the prayers of Sisters over the years and decades. We are truly a sanctuary from the pressures of everyday where, regardless of the nature of your meeting, you will find your spirit nourished.

Without exception, every person who passes through the gates into the grounds of Rosary Priory on his/her way to a meeting, course or retreat, experiences the unique peace of the property and is refreshed.
