Our Mission

Gender Spectrum’s mission is to create a gender-inclusive world for all children and youth. To accomplish this, we help families, organizations, and institutions increase understandings of gender and consider the implications that evolving views have for each of us.

Who We Are

Our Board of Directors

Our Staff


Joel Baum (he/him)
Senior Director, Professional Development

I facilitate trainings, conduct workshops, develop curriculum, consult with parents/professionals, and provide resources in service of a more compassionate understanding of gender and young people. I have served in a leadership role as the Director of Education and Advocacy with the Child and Adolescent Gender Center at UCSF-Benioff Children’s Hospital. An aspect of my job that I enjoy the most is working throughout the United States (and beyond), to help institutions think more expansively about the gender diversity of all children and teens, and ways to create more inclusive conditions accordingly.

I’ve worked as an educator focused on issues of social justice and equity for over 30 years. My education career began as a middle school science teacher and school administrator. I have also served as a district administrator in Oakland, California, as well as a school reform coach with the National Equity Project and professor at California State University, East Bay in the Department of Educational Leadership.

Yarrow Halpern (they/them)
Manager of Online Programming

Yarrow (who is Non-binary) began their role at Gender Spectrum in June 2019. They graduated with Honors from Mills College with a BA in International Relations and a double Minor in African Diaspora Studies & Spanish. They speak Spanish, English and French. They are a radical, queer, black, brown, and indigenous femme and healer. Bay Area born and raised, community work is incredibly important to them and they have worked in nonprofits for 13+ years. When not working at Gender Spectrum, they facilitate groups and workshops as a Fat Positive Facilitator and also do Diversity, Equity and Inclusion consulting. Their lens is intersectional. They are committed to uplifting the voices of black and brown folx doing this work. Making the world a more equitable place is at the heart of everything they do.


Jenna Hackman (they/them or she/her)
Director of Online Programming 

Jenna identifies as a non-binary queer person. They have been involved with Gender Spectrum since 2014 starting out as a volunteer at the annual conference. Jenna is passionate about social justice and creating accessible online spaces and resources for youth, parents and professionals to gain better understandings around gender and the intersections within that. They enjoy creating resources, presenting at conferences and simply having conversations about how rigid ideas around gender impact all youth. Jenna has been working with youth in various capacities for the past decade and enjoys empowering young people to be their authentic selves and supporting adults in creating affirming environments for youth to thrive. In their free time Jenna enjoys spending time with her wife, 3 pups, queer community and family (they love being a queer, non-binary aunt!)


Lisa Kenney (any pronouns are ok)
Member of the Board of Directors and Executive Director

As a member of the Board of Directors, my role is to work with my fellow board members to create a vision for the organization and establish the strategic priorities to help ensure that the organization is able to further its mission to create gender inclusive environments for all children and youth. As Executive Director, my role is to successfully lead and manage the organization consistent with the direction set by the Board of Directors.

I’m thankful to be a part of the Gender Spectrum team and to have such a talented, passionate, and dedicated staff to work with. Before joining Gender Spectrum, I served in a number of corporate leadership roles, including VP of Strategic Technology at Incyte Genomics and VP of Global Marketing at Genedata. I often speak at conferences and consult with organizations on the changing understanding of gender and the implications this has for families, social institutions and corporations. With Stephanie Brill, I co-authored “The Transgender Teen: A Handbook for Parents and Professionals Supporting transgender and Non-binary Teens.”

Candace Lopez (she/her)
Development Director

I’m grateful to come on board as Gender Spectrum’s first Development Director.  My job is to ensure that we have the resources needed to sustain this very important work.  As a non-profit organization we rely solely on community support. That means individuals, organizations, foundations, and others have a profound opportunity to help us sustain this life-changing programming.  I’m here to help our supporters and potential supporters understand the depth and breadth of what we do and find out how we can partner together to continue building a gender-inclusive world.

I have worked in non-profit development for over 10 years for varying organizations and causes including civil liberties, worker advocacy, sexual assault and domestic violence, higher education, and the arts.  I enjoy learning about people, their philanthropic interests, and matching these interests with giving opportunities. The mission of Gender Spectrum is a deeply personal one for me, and I look forward to working hard to ensure this organization remains thriving for years to come.  


Charles Margulis (he/him)
Communications Director 

I am happy to work in support of gender inclusive environments for all children and youth as Gender Spectrum’s Communications Director. Previously I worked to end the uses of toxic chemicals that threaten the health of children and adults, and to address the health and environmental risks of genetically engineered foods. Prior to that I served as a volunteer workshop facilitator for a men’s anti-violence and anti-sexual assault nonprofit. I also spent many years as a baker and pastry chef, including working at the United Nations where I made petit fours for Nancy Reagan (she said they were delicious).  



Kim Westheimer (she/her)
Director of Strategic Initiatives

I engage partners, funders, policy, and research to support the fundamental mission of Gender Spectrum. I also conduct program development and evaluation, develop written materials, and present at national education conferences. I believe strongly in the power of relationship building and collaboration to bring together diverse organizations committed to the health, safety, and well-being of all children and youth.

My career in nonprofits and education has centered on generating opportunities for educators, students, and parents to work together to create inclusive spaces for all students. Immediately before joining Gender Spectrum, I directed the launching of at the Human Rights Campaign Foundation’s Welcoming Schools Program, created in 2007 to foster LGBT inclusion in elementary schools. I also directed the Safe Schools Program for LGBT Students at the Massachusetts Department of Education and chronicled the lessons learned from that time in the book When the Drama Club is Not Enough which I coauthored with Jeff Perrotti.
