What it is like to work with me
My style is warm, direct, collaborative, and structured.
I listen for patterns, help you make sense of what is happening, and look for places where a different response is possible. Sessions may include conversation, psychoeducation, whiteboard work, practice, or something to try between sessions.
A Good Fit
Research indicates that the relationship, or therapeutic alliance between therapist and client is essential for positive outcomes. While part of being a good fit can not be expressed on paper, here are some ways I have been described.
Sex is welcome here
You do not need to be coming to sex therapy to talk about sex. If sexuality or intimacy affects your relationship, your sense of self, or your ability to communicate, it belongs in the room.
A relational and systemic lens
- I pay attention to what happens within you and between you and other people.
- That includes the ways family, culture, identity, power, relationships, and life circumstances affect the problem you are trying to solve.
Systemic thinker
I consider your immediate concerns through an anti-racist and anti-oppressive lens. This means naming and considering the way race, gender, sexual orientation, socio-economics, family dynamics, culture, generational and relational stressors impact you. We name power imbalances in and out of the room.
Sex-positive and body-positive care
Sexuality develops across a lifetime and is shaped by relationships, experiences, values, culture, and our relationship with our bodies. I approach these conversations slowly and collaboratively, with attention to consent, autonomy, and what matters to you.
Areas of interest
People often come in with concerns that overlap. This list gives you a sense of the themes that are welcome here.
Approaches
I draw from relational, developmental, behavioral, and nervous-system-informed approaches depending on what is useful for the person or couple in front of me.
Developmental Model
The Developmental Model views relationships as evolving through stages, focusing on increasing differentiation and mature connection rather than treating pathology. It combines attachment theory, differentiation, and neuroscience to support facing challenges, improving communication, and building resilient relationships for the long-haul.
Common questions
What is a CST?›
CST means Certified Sex Therapist through AASECT and reflects advanced training and supervised experience in sexuality and intimacy.
Do I need a specific reason to bring up sex?›
No. Sex does not have to be the main reason you came to therapy. If it affects your relationship or sense of self, we can talk about it.
Is sex therapy only for couples?›
Sex therapy is available to individuals and couples. You can come on your own to discuss sexuality or intimacy; a partner does not need to attend.
What are sessions like?›
Sessions are collaborative and structured around what you bring in. I listen for patterns, ask questions, and help you identify a useful next step.
Do you work with faith transitions and mixed-faith relationships?›
Yes. I work with people navigating changes in faith and with partners whose beliefs differ. We can talk about how those differences affect identity, communication, and your relationship.
Do you work with LGBTQIA+ clients?›
Yes. I welcome LGBTQIA+ clients for individual, couples, and sex therapy. We can focus on your relationships, sexuality, identity, or whatever brought you in.
For Healthcare Professionals
If you are a clinician referring patients or clients for specialized sex therapy or couples therapy, I welcome collaboration with therapists, physicians, prescribers, and other healthcare providers.
