Head of Department Rituals

Sandra Hiltmann, since 2022 responsible for rituals and member of the board of the section NWS.
Born 1966 in Basel, happily married, two adult children, originally mechanical engineer HF, humanist celebrant.

After becoming aware of the Giordano Bruno Foundation in Germany, she was looking for an association in Switzerland that represents the values of evolutionary humanism and is committed to rationality and above all the secularization of the state.
The training offered to become a humanist celebrant also appealed to her.
This is how she found the Freethinkers Association of Switzerland and since then she is involved as a member, since 2020 as a board member of the section NWS and since 2021 as a central board member of the FAS.

She helps with the organization and implementation of Camp Quest and through her many years of experience in the distribution of craft products, she designs the respective camp t-shirt with the kids.
In 2020, she completed the FAS humanist celebrant training and has been conducting farewell, wedding and welcome ceremonies ever since.
In 2022 she then took over the department of rituals and now also organizes the training of the humanist celebrants.
