Sydenham High Alumnae Network

Every Sydenham High student automatically becomes an alumna when they leave the school. They also join an unrivalled worldwide network of more than 70,000 women who have experienced a GDST education.

There’s no charge to belong to the alumnae network, so if you don’t already hear from us or the GDST, please register here to receive our termly Sydenham High alumnae e-newsletter and GDST e-zines, as well as to gain access to exclusive events and career networking opportunities. By registering with the GDST, we will also access your details and be able to contact you about upcoming events or special projects should you so wish.

Visits & reunions

Former pupils are always welcome back at Sydenham High, in and out of term time. If you’d be interested in visiting the school, have plans to organise a class reunion, or just want to let us know what you’ve been up to, we’d love to hear from you! Contact us at:  or call us on 020 8557 7066.

Mentoring and career guidance

In a time-honoured tradition, we look to our alumnae to help current pupils as mentors and career guides. We would be delighted to hear from former pupils who can offer their time by way of talks, individual mentoring or offers of work experience. Please contact us at  or call us on 0208 557 7011 if you can help.

Staying in touch

To update your details, you can email , or post a letter to the school for the attention of Wonnie Sayama. Alternatively, you can update your basic details on the GDST website.
