Genevieve Marie Gellert, MSW, LCSW, CST

FOUNDER OF THE CENTER FOR IDENTITY & SEX THERAPY

Hello,

You’re here because something in your life — or within yourself — has shifted.

You can find your way back yourself, even after everything changes. You are not broken. You are becoming. Every part of you is welcome here.

You’re at a crossroads, disconnected from your body, sex, or identity. You’ve mastered distraction—scrolling or numbing out—frustrated, in pain, or isolated. You’ve tried the books and tricks, yet feel trapped by relationships or patterns you can't shake. Maybe there’s a loneliness you can't quite name. Intimacy feels overwhelming, desire muted, arousal inconsistent amid dysfunction, shame, or guilt. You prioritize others or say yes when you mean maybe. Whether navigating kink, polyamory, LGBTQ, modern dating, cultural, or faith expectations, you're torn. You can heal the deeper roots keeping you stuck, far beyond surface symptoms.

Founder of the Center for Identity & Sex Therapy, I’m an AASECT-certified sex therapist with a Master’s from the University of Pennsylvania, specializing in health, cross-cultural & life transitions impacting identity, sexuality, body image & intimacy. We offer premier relational, psychodynamic care—to hold what hurts, ease anxiety, and gain clarity.

You’re not alone. You inherently deserve safety, vibrant relationships, body confidence, intimacy, joy, pleasure, desire, and satisfaction. Sexuality is inseparable from identity. History shaped the rules. You choose the healing. And that healing begins with the freedom to be completely who you are. Ready to feel aligned? Message me here for a consultation.

Warmly,

Genevieve Marie Gellert, MSW, LCSW, CST (she/her)

    SEXUALITY & MENTAL HEALTH EDUCATION INTERN | SOCIAL MEDIA MANAGER

    Julianne Stainkamp is an undergraduate student at Stony Brook University, pursuing a bachelor’s degree in Sociology with a Psychology concentration and a dedicated focus in human sexuality and sex education. Throughout her academic career, she has conducted advanced coursework and research exploring the sociological explanations of societal taboos surrounding sex. Driven by her goal to complete a master's degree in Social Work and practice as a licensed sex therapist, Julianne joined The Center for Identity and Sex Therapy as a clinical intern. Beyond her primary research, she brings valuable experience in local community commerce and university student leadership, which she leverages to foster inclusive, destigmatized environments.

You are more than symptoms to manage.

Your relationship to pleasure, intimacy, and identity isn’t a technical dysfunction to solve.

Much of modern sex therapy approaches personal pain like an isolated medical equation—isolating the symptom, running through a structured manual, and handing you generic behavioral checklists to "fix" your intimacy.

But boundary struggles, lost desire, and blocks to pleasure are not mechanical failures. They are historical, cultural, and deeply relational. We move beyond individual self-help and into relational, systemic depth.

At the Center for Identity & Sex Therapy, we help resolve the immediate sexual health issue—but we do not stop there.

We reject the cold, detached model of the silent clinical observer. Instead, our practice integrates evidence-based sexual health expertise with warm, active, relationally-oriented psychodynamic care. Working through a collaborative two-person psychology, we use our real-time partnership to quiet the nervous system, conquer shame, and dig beneath the surface of your symptoms. Together, we unpack the systemic and generational currents shaping your desire, freeing you to claim a pleasure and an identity that is authentically your own.

Built for Vulnerability and Depth

Whether you are navigating the profound, identity-shifting matrix of a major life transition, or safely deconstructing complex, layered questions surrounding sexuality, grief, trauma, and identity—you do not have to carry the weight alone.

You are invited to move past rigid symptom management and build a foundation for radical personal victory.

Your identity and sexuality are at the heart of who you are — meant to be explored, celebrated, and accepted.

HEre’s what I believe about therapy:

This isn’t about going back to how things were.

It’s okay that change feels hard, and you don’t have to be okay with it yet. Together, we can find a way forward — in your body, relationships, and life.

The best investment you can make is in the confidence to be yourself.

Building trust in who you are, your identity, and the choices that honor your values is at the heart of this work.

You are inherently deserving of safety, joy, pleasure, desire, and satisfaction.

Exploring your sexuality and intimacy creates a path to fulfillment and genuine connection.

Where Frontline Clinical Rigor Meets Premium Care

Clinical Foundations & Experience

Grounded in intersectional feminism, I believe that sexuality and identity are entirely inseparable—shaped by how we see ourselves, how we are seen, and how we connect. My practice is built on a deep respect for your absolute autonomy, your complexity, and the unique path you take to understand yourself.

After earning a Bachelor of Science in Health Policy and Management from Providence College and following my graduate training at the University of Pennsylvania, my clinical worldview was forged through diverse, frontline experience across medical, community, crisis, and end-of-life settings in Philadelphia, including:

  • Penn Medicine & Thomas Jefferson University Hospital: Specialized training within the Penn Memory Center and Department of Geriatric Psychiatry.

  • Crisis & Emergency Settings: Counseling sexual assault survivors through acute trauma.

  • Public Health & COVID-19 Response: Consulting on behavioral health and designing integrated care programs for low-income, pregnant, and homeless LGBTQ+ individuals in North Philadelphia.

  • Community Harm Reduction: Supporting straight and queer sex workers navigating stigma, safety, and systemic survival in a methadone clinic.

  • Hospice & Memory Care: Serving as an end-of-life social worker providing family counseling, and supporting older adults (including trans older adults) with dementia navigating intimacy, consent, and sexual expression.

Transitioning from Urban Medical Social Work to Private Practice & Healthcare Entrepreneurship

Inspired by Viktor Frankl, my entrepreneurial transition was driven by a desire to guide clients to say a resounding “yes to life, in spite of everything,” treating each day as an opportunity to live fully for a second time. Together, we explore how your deepest, most challenging life experiences can be reclaimed, integrated, and transformed into a life that feels genuinely aligned and entirely your own.

As one of fewer than 900 Licensed Clinical Social Workers worldwide who are AASECT-certified in sex therapy, I bring elite, specialized expertise to navigate complex relational dynamics, sexual trauma, dysfunction, and intimacy concerns safely and ethically.

To bring this vision to life, I developed the ALIGN Framework—my signature model of sex therapy. This boutique, integrative approach blends humanistic, meaning-centered, cognitive-behavioral, and somatic modalities, engineered to help you actively inhabit your body, heal from identity-based harm, and fully reclaim your intimacy, confidence, and desire.

Following a successful group practice launch at the Philadelphia Institute for Individual, Relational, and Sex Therapy and part-time solo private practice, I opened a full-time private practice in 2021—maintaining a 95% client retention rate and a 70% consultation conversion rate.
