Dr. Marion Sewer served as a member of the Mentoring Committee of WE from 2010 to 2012. When she joined the committee, the committee was just embarking on new collaborations with the Trainee and Career Development Core Committee of The Endocrine Society. Dr. Sewer’s participation facilitated the committee’s discussion and decision making on a number of trainee development programs. These programs have benefited many endocrine trainees, particularly female trainees, in their career development. Dr. Sewer will be missed and remembered as a valuable committee member and caring colleague. Her dedication as an active member of WE was also notable for her annual attendance at board meetings to make contributions and lend support to other aspects of the organization and the mission.
