Transforming the harsh voice into one that heals —
for Women, Young Adults, and Couples ready to break the cycle.


Virtually across NY and MA, & in person in Fishkill, NY

Something in you already knows it's time.

Maybe you're exhausted from fighting your body, or carrying the weight of a voice inside that's never satisfied. Maybe your relationship feels further away than it used to, or you're standing at the edge of adulthood wondering why everyone else seems to have a map.

You're not broken. You're ready.

This is therapy for the cycle breaker — for the person ready to look honestly at how the past is affecting the present, and how outdated beliefs are keeping you stuck. Whether you’re struggling with disordered eating, body image, the overwhelm of early adulthood, or a relationship that needs real repairyou already have the courage. I’m here to help you build the tools.

Hi, I’m Sienna


I became a therapist because I believe healing isn’t something that happens to you — it’s something you step into,one honest moment at a time.

My approach is rooted in mindfulness — not as a technique, but as a way of learning to be truly present with your own experience, even the parts that are hard to sit with. Especially those parts. Over the years I’ve sought wisdom well beyond my own cultural horizon, and what I’ve gathered has shaped a deep conviction: that even the discomfort you’ve been running from has something to offer. That sitting with it, rather than away from it, is where the real shift begins. In therapy, you don’t have to sit with it alone.

I don’t hand out worksheets. I help you understand why you do what you do — and that changes everything.

You don’t have to downplay your story here. You will be met with full presence, deep listening, and the unwavering belief that you are more capable of putting down what you’re carrying than you know.

If you’re ready to move from managing your inner critic to listening to your own deepest wisdomwe’re going to do extraordinary things together.

Who I Work With

My work centers on three areas — each one a different doorway into the same deeper work of learning to live from your truest self.

How To get started

Reach out for a consultation. This is a chance for us to meet — for you to ask questions, share what's bringing you in, and get a feel for whether we're a good fit. No pressure, no commitment. Just a conversation.

Do the real work. This is where we dig in — honestly and at your own pace. I'll be with you every step, offering insight, new tools, and the kind of presence that makes it feel safe to go deeper than you have before.

Start living from your truest self. As the work takes hold, you'll begin to notice shifts — in how you talk to yourself, how you show up in relationships, and how it feels to move through your life. That's the point. That's what this is all for.
