A Message From the Co-Presidents


Building for the Future Together is our theme for this year and our emphasis is on the word together.  It seems especially appropriate during this year of continued disruption due to the pandemic, that the Presidency is a partnership between two women who are more than ready to face the task of moving us into our 99th year.

Phyllis McMaster Moist is a retired reading specialist and Area 3 Writing Project teacher leader who joined Soroptimists in 2015 and has served on the Board since as Assistant Treasurer, Corresponding Secretary, 2nd Vice President, 1st Vice President as well as co-chair of the Scholarship Committee, the See’s Candy Fundraiser and was part of the original team that created our Dream It Be It program.

Cathy Conway Diepenbrock is a Customer Service Representative for SMUD who joined Soroptimists in 2015 and has served on the Board as 2nd VP, 1st VP and now co-President. She has also co-chaired both the Live Your Dream Committee and the Edible Garden Tour Committee for several years.

As the first co-Presidents of SIS, Cathy and Phyllis are committed to Soroptimist’s vision, mission and core values and the idea that together we can do more with our shared value— collaboration.

We are proud of our club’s long history and the contributions made to our local community. Our focus remains committed to the important work of Soroptimists, locally and globally:

  • Gender Equality
    • Women and girls have the resources and opportunities to reach their full potential and live their dreams
  • Empowerment
    • Women and girls are free to act in their own best interest
  • Education
    • Women and girls deserve to lead full and productive lives through access to education
  • Diversity & Fellowship
    • Women from varied backgrounds and perspectives work together to improve the lives of women and girls

We are grateful to be a part of a diverse, inclusive and talented group of women leaders, ready to empower all women and girls to make our world a better, more equitable place.

With sincere gratitude,

Phyllis McMaster Moist and Cathy Conway Diepenbrock
