SMLS Alumnae

Girls who attend SMLS enjoy lifelong friendships with their fellow students, and are welcome back to their school anytime! We have a strong Alumnae Association of empowered women who can be found living and working across the globe. A number of our alumnae have sent their daughters to the school, constituting second and third generation Millies - a testament to our exceptional educational experience. Once a Millie, always a Millie!
