Mentoring programs for career and personal development have shown to be incredibly beneficial for mentees, boosting their work and life satisfaction. Mentoring programs are particularly important for women in academia, where they are usually a minority. In 2021, in the context of the commission of Women in Astronomy of the Spanish Society of Astronomy, we started a mentoring program for female astronomers to support their careers. In the first two editions, we have more than 50 participants between mentors and mentees. In the mentoring program, we assigned a mentor to each mentee, according to their preferences and objectives. To encourage networking, we carry on group peer-mentoring sessions among mentors and mentees. Finally, we organized training sessions for mentors and mentees with the aim of boosting their career development.
