Joel Baum

Senior Director, Professional Development

(pronouns: he/him/his)

As a cisgender man, our binary model of gender should serve me well. Theoretically, it is literally designed around my experience. But like so many others, it has failed me. The expectations in every dimension of gender--to have particular physical attributes, to dress and act in rigidly masculine ways, to carry a sense of self that is "manly"--have resulted in a great deal of unhappiness and damage as I have sought to reach these imposed definitions of who I am supposed to be. I truly believe that a more gender inclusive world will liberate all of us, and am proud to play even a tiny role in that process.

Jenna Redmond (Hackman)

Director, Online Programming

(pronouns: they/them or she/her)

I strongly believe that gender should unleash the possibilities in every human instead of limiting them. As a queer & non-binary person the world often feels like it wasn't set up for me. I feel so grateful to get to spend my time at Gender Spectrum creating Online Spaces for youth, families and professionals to build community and simply not feel alone. Being outside of traditional gender norms can be exciting and energizing but also terrifying and lonely. I can't wait for a world in which Gender Spectrum is no longer needed and all kids are celebrated for who they are!

Yarrow Halpern

Manager, Online Programming

(pronouns: they/them/their)

I am a femme and I am non-binary. One does not negate the other, they exist in duality. My gender ebbs and flows like the tides. This has allowed me to truly redefine the role gender plays in my life.  I no longer follow gender like a map, I follow my heart and my body and my mind follows suit. My gender is intuitive.

D Han

Administrative Assistant

(pronouns: they/them/their)

I am glad to have found myself in the cozy corner of the world that is Gender Spectrum. In what has heretofore been an unplanned and probably illogical work life, spent primarily contributing to a few too many missions (youth services, environmental causes, public health) of Bay Area mission-driven organizations, it's been a breath of fresh to participate in work that has a more personally meaningful focus, and that opens doors to other aspects of my experience that intersect with gender: family, culture, and faith upbringing.

Kim Westheimer

Director of Strategic Initiatives

(pronouns: she/her)

When I think about gender in my own life I recall that as a child I knew there were rules about gender but these notions didn't speak to me. I really didn't understand them and didn't know what to do with them. In contrast, it's exciting to be living in a moment in which people - especially young people - are creatively taking the lid off of gender boundaries and binaries. I truly believe that this will be a positive thing for all of us!

Liam Day

Interim Executive Director

(pronouns: he/him/his)

Gender Spectrum is the first stop in my professional career where I have grappled with gender as a concept, but I realize that I have been grappling with it in practice all my life, even when I didn't know I was. The strictures of what our society has traditionally defined as masculine leave a large number of people outside that definition. In some ways, I fit perfectly society's traditional definition of masculinity; in others, I did not. I am happy to be at Gender Spectrum both to share my knowledge of and background in nonprofit management, and to expand my learning of gender and reflect on it in my own life.

Carla Peña

Program Coordinator

(pronouns: they/them or she/her)

I am thrilled to be a part of the Gender Spectrum (GS) team! As a queer, non-binary person of Cuban and Puerto Rican descent, I struggled growing up to find folx whose gender experience mirrored my own. As the youngest of three children, and the only child raised as a girl, I quickly learned what was deemed appropriate gender behavior for me and what was not. So when I first learned about Gender Spectrum, I couldn’t help but imagine how much heartache I could have been spared if an organization like GS had existed when I was younger. Because of this, my wish for all people, but most especially, young people is: that the world they inherit be one where they are able to grow into themselves and their gender, free from expectation, limitation, and judgment, and full of joy and acceptance.
