My qualifications and experience

I have a PhD in Education at the University of Modena and Reggio Emilia.

I have been working with children for over 12 years and have been living in Australia for the past 8 years. During my time in Australia, I have always worked in the early childhood sector in leadership positions.

I joined SDN Mosman as Centre Director in 2023.

What I’m most passionate about in my role

I am passionate about the co-creation of projects with children, families, and staff. In project-based learning, we don’t impose a vision on children, but we work collaboratively with children to build a vision based on their interests. This way of practice supports children’s ability to think critically and flexibly and make them active citizens of this world.

I am also passionate about quality approaches to early childhood and care, and attending professional development conferences, both local and international.


What I love about working with SDN

I love that at SDN we plan and practice with intentionality, such as in preparing learning environments for children.

I also really love that our families feel secure and supported here, and in-turn they support our centre back with warm participation. Our team feels a real sense of honour in building reciprocal relationships with families.


A little bit more about me

I see myself as a global citizen of the world. I have completed internships and worked in Rome, New York and Sydney. This is why I believe so passionately about children becoming citizens of the world.

In my spare time I take dancing classes. I am a people person, who treasures friendships and building connections. I can also speak Italian and English.

Infant & toddler educational program
Toggle Accordion

Growing bodies need movement and exercise. Growing minds need stimulus and exploration. Growing hearts need opportunities to play and mix with others.

At SDN we know that the best thing we can do for your infant or toddler is to support them to grow and develop in safe, unhurried, nurturing and challenging environments.

Because infants and toddlers are naturally curious, our centres have well-equipped indoor and outdoor areas that will keep your child moving and give them daily opportunities to explore their limits and grow their abilities.

Your child is unique and so we will devise a learning and development program within our curriculum pillars, based on what we know about your child’s interests, learning and development. Because they will always be changing and growing, we consistently review the program to ensure we are keeping up with your child’s development, providing them with the best learning opportunities.

Preschool educational program
Toggle Accordion

Get more than school-ready, get life-ready 

Getting school-ready is a journey. It begins with your child’s very first day at our welcoming early education and care centres and continues with our dedicated preschool program.

Developed by university-trained early childhood teachers, our preschool program focuses on the whole child. Children learn to make friends and work together, while gaining the skills and independence they need to thrive through the big transition to school.

Our preschool program follows an evidence-backed, play-based learning approach. Children have fun and follow their curiosity, while we weave in vital skills and learning outcomes.

SDN uses Australia’s Early Years Learning Framework to explore a diverse curriculum from science to social justice. Our days are predictable but flexible, blending structured and spontaneous learning, free play, movement and quiet time.

Our curriculum pillars are:

 Relationship and social skills

 Critical thinking and problem solving

 Early literacy and numeracy

 Health, wellbeing and movement

 Science, technology, construction and design

 Nature play and sustainability

 Creative arts

 Equity and social justice

Our centres have a transition to school program where our teachers and educators work together with local schools to prepare your child for a smooth transition, and support families through the process.

Outdoor space
Toggle Accordion

Families in our urban based centres often call our outdoor areas their “green oasis”.

SDN's outdoor spaces provide opportunities for children to enjoy themselves and have adventures. They’re safe environments for children to run, jump and yell, make mud cakes, and use their energy.

Outdoor spaces provide more than physical benefits. Even though you may think that children only play outside to have fun, they're also improving their thinking, social, and emotional skills. When they’re playing outside, they’re inventing games, learning about the world at their own pace, and figuring out social customs like turn-taking.

These are just some of the reasons SDN invests in developing new, award-winning outdoor spaces with natural designs that inspire children’s curiosity, physical play, and social play.

Centre history
Toggle Accordion

The traditional owners of the area now known as Mosman are the Kuringgai People.

SDN Mosman opened in 1944 at 33 Brierley Street, a residential house that had been purchased by SDN in 1943 and converted into a nursery school.

Mosman’s large Federation-style houses were home to professionals and artists. During the Second World War, the need for long daycare and nursery schools in the Mosman area became apparent as more women took up work, or worked for long hours.

In 1976, the nursery school’s ‘old cottage’ house was replaced with the current building, which still provides a light-filled, modern environment for the education and care of children more than 40 years later.

Since its beginnings, SDN Mosman has reflected a strong connection with local families, and supported SDN's vision and commitment to enhance the wellbeing and development of all children.

From 7 August 2023, our fees will be $218 per day for children under three years old and $199 per day for children three years and over.

SDN Mosman also offers half day sessions. Half days are $129 for 0-3 years and $117 for 3-5 years, from 9am to 2pm.

The majority of families in our centres do not pay the full daily fee because they receive Child Care Subsidy (CCS) from the government.

The subsidy you may receive through the CCS will depend on:

  • Your combined family income
  • The number of hours you work, study or participate in recognised volunteer work. This is called the ‘activity test’. If your child is in the year before school, if you are on a very low income, or if you are on parental leave, you will not have to pass the activity test to receive some CCS.

Your child will need to meet immunisation requirements and you will need to meet residency requirements to be eligible to receive the CCS.

Try our CCS estimator tool here.

You can also calculate what your out of pocket child care costs will be on the government’s child care subsidy calculator.

Additional Preschool fee relief

In addition, the NSW Government is providing up to $2110 in fee relief for preschool aged children who are enrolled in the preschool program at SDN Children’s Services from 2023.

If your child will be 4 on or before 31 July 2023, this additional funding could mean up to $40 a week in fee relief to your family, on top of the existing child care subsidy.

If you’ve read this information and you’re still unsure about what you’ll pay, please call us or book a centre tour. We’re happy to answer your questions.

Occasional care for your child
Toggle Accordion

At SDN we want to ensure that all families have access to high quality, inclusive education and care as we provide at SDN Mosman. That’s why we offer the opportunity to enrol for occasional care at this centre.

Families in flexible care have the opportunity to take a full or a half-day place and must make at least one booking every 8 weeks.

Occasional care bookings are taken subject to availability on the day and you can book occasional care for either a full day or a half-day.

Half day fees will be $129 for children under three years old and $117 for children three years and over.

To find out more call us on 1300 831 445.
