173 Waterman St. Providence RI 02906

Sarah (Sid) Treaster, LCSW in Rhode Island (they/them) is a queer, nonbinary Individual, Couples and Sex Therapist at the Center for Growth. They provide in-person and virtual therapy to individuals, groups, couples, and other alternative relationship formations. Sid draws heavily from Narrative Therapy, Emotion-Focused Therapy, Strength-Based Therapy, Cognitive Behavioral Therapy, Solution-Focused Therapy, and Mindfulness practices in their work with clients.

Sid views their therapeutic practice as an ongoing collaboration with their clients. Working together, they will explore clients’ relevant histories, examine client values, set goals for treatment, and tailor any therapeutic interventions to the needs of the client (or clients) instead of using a “one-size-fits-all” approach. Sid knows that clients are the experts on their own lives and wants to help clients work towards their goals and reach their full potential through a safe, empowering, therapeutic alliance. 

Sarah (Sid) is a Licensed Clinical Social Worker in Rhode Island and is currently working toward getting their LSW in Pennsylvania and New Jersey. They offer in-person therapy sessions at the Providence, Rhode Island office as well as virtual sessions for those living in PA and NJ.



Sid was born and raised in Santa Fe, New Mexico, where they found a love of ballet that moved them all over the country throughout their high school experience. Sid received their bachelor’s degree in Gender and Women’s Studies at Connecticut College in the small town of New London, Connecticut. Following graduation, they worked at a crisis center in Lynn, Massachusetts as a Sexual Assault Counselor and Educator for a few years before enrolling in graduate school. This job allowed them to dip their toes into the world of therapy, as well as give them beneficial experience providing sex and consent education in high schools and colleges which they came to love. After a three-year dual-degree graduate program, Sid acquired a Master of Social Work and a Master of Education in Human Sexuality in which they completed the Sex Therapy specialty track. 

During their graduate degree program, Sid interned at Riverside Community Care’s transitional therapeutic day program for teens in Massachusetts that specialized in treating individuals experiencing symptoms of psychosis. Here, they regularly facilitated adolescent groups in art therapy, movement therapy, narrative therapy, cognitive behavioral therapy, and dialectical behavior therapy. Many of these groups centered around discussions of gender, identity, race, sexuality, and how those experiences intersected with mental health. In their final year of graduate school, they interned at Boston GLASS, a program of Justice Resource Institute that serves LGBTQ+ youth of color ages 13-29. Sid provided outpatient therapy to a caseload of clients who presented with issues including but not limited to depression, anxiety, mood disorders, personality disorders, gender dysphoria, body dysmorphia, self-esteem issues, disability, familial conflict, relationship issues, discrimination, and oppression.

Sid has worked with a multitude of mental and behavioral health issues, such as mood disorders, anxiety, personality disorders, trauma, and psychosis, with their most extensive experience in gender identity, depression, and sexual trauma. They have worked closely with a wide range of clients in age, race, culture, ethnicity, ability, socio-economic status, religion, gender identity, and sexual orientation. Sid recognizes that identity is deeply entangled with a person’s individual experience, and they strive to use an anti-oppression approach in their therapy practice. Ableism, ageism, sexism, racism, fatphobia, whorephobia, queerphobia, transphobia, and many other forms of oppression can all play a part in a person’s relationship to their mental health, and these factors are not to be ignored in the therapy process. Sid is dedicated to using an intersectional lens and whole-person view when engaging with their clients in an attempt to acknowledge all the factors that contribute to a person’s unique life experience. 


Therapeutic Style

There are far too many places in our world today where we are forced to face discomfort, lack of safety, and to feel deeply misunderstood. Sid’s goal is to cultivate a comfortable, relaxed, warm (but still chill), and safe environment where clients are free to be their most authentic selves. Sid prioritizes building a strong therapeutic rapport with their clients for their work together to be successful. This means leading with empathy, kindness, humor (when appropriate), and zero pressure to ever share anything that someone might not yet be ready to. Sid welcomes honest feedback from clients to better adapt to their individual needs and desires in the treatment process.

Sid strongly believes that all people have a right to pleasure and deserve a healthy, fulfilling, satisfying relationship to their bodies. As a Sex Therapist, Sid works with clients on issues of sexual function and helping clients get to the root of their issues to promote change as opposed to just sticking a band-aid on the symptoms. Sex Therapy attempts to address sexual function issues by enhancing clients’ focus to the many unique physical sensations and emotional experiences that one can discover with themselves and with partners. Sid encourages clients to allow themselves to take risks and to expand their sexual curiosity, beliefs, emotions, and definitions of pleasure to allow for change to take place. Through the use of thorough assessments, various mindfulness techniques, and take-home exercises, Sid can support clients in raising their awareness and connection to their minds, bodies, and sexual values.

Take a moment a think about what and how you learned about sexuality growing up. What did your family teach you? What didn’t they teach you? What about your school? Social media? Your friends? Religion? Your culture? What are your values now? Where did those values come from? How did they come to be? How have they changed over the years?

Here are a few things that come to mind for Sid when they think about what society taught them about sex: Sex is ever-present in our society, yet discussing it openly is often met with discomfort, shame, and seen as taboo. Society gatekeeps sexual autonomy and the open discussion of sex from certain groups of people, like people with disabilities and people who are aging. The denial of sexual agency to these individuals perpetuates harmful stereotypes and contributes to a lack of comprehensive sexual education and support tailored to their unique needs. Sex is encouraged for some genders; other genders are shamed for it. Some people are hypersexualized, reduced to narrow and often exaggerated stereotypes, while others are infantilized, denied agency and treated as if their sexuality is non-existent or irrelevant.

Many different confusing and often oppressive messages can seep into our personal experiences of sex and can have a deep impact on how we relate to ourselves, our partners, our entire worldviews. If you are experiencing difficulties in sex, these can be due to a myriad of factors including any of your answers to the questions posed above. Societal, psychological, biological, familial, religious, and other cultural influences and issues can all play a part. In the pursuit of their work as a sex therapist, Sid is dedicated to unraveling these narratives and fostering a more compassionate, inclusive, and sex-positive environment. By challenging harmful stereotypes, advocating for the rights of marginalized groups, and promoting open conversations about sexuality, Sid strives to create a space where individuals can explore, understand, and embrace their unique sexual journeys without judgment or shame.

In their sex therapy practice, Sid approaches each client with empathy and a commitment to creating a safe and relaxed space. The process often begins with a series of thoughtful, thorough, and respectful questions, allowing Sid to understand each individual’s unique history in relation to sexuality. Most importantly, clients are never obligated to answer anything they’re not comfortable with. This is a fully consent-based practice!

The sex therapy process will be more than just talking about the act of sex itself; sex therapy is about delving into the rich tapestry of a client’s attitudes, behaviors, and goals surrounding sexuality. Sexuality also extends far beyond the physical realm; it encompasses pleasure, pain, relationships, family history, emotional landscapes, and more. Through open and non-judgmental conversations, Sid aims to collaborate with clients to unravel the layers of their sexual narratives, offering support and guidance on a route towards a healthier, more fulfilling relationship with their own sexuality.

Sid has a great deal of knowledge about working with those who are poly/ENM and the intricate challenges and complexities that can arise with balancing multiple relationships and connections. Additionally, Sid welcomes clients who are in the kink and BDSM communities, as well as individuals involved in sex work. Sid strives to provide non-judgmental, supportive sex worker-affirmative therapy using a harm-reduction, workers-rights, non-pathologizing perspective. Sid works to foster a therapeutic space that recognizes and respects the diverse experiences within these communities.

Whether grappling with challenges related to communication, desire, intimacy, or any other aspect of sexual well-being, Sid’s approach is holistic and affirming. By acknowledging the interconnected nature of sexuality with other aspects of life, they empower clients to explore, understand, and ultimately transform their relationship with themselves and their partners. In Sid’s therapy room, every client is respected, heard, and supported on their unique path towards sexual empowerment, autonomy, and overall well-being.
