I’m a licensed therapist with a background in social work, and I’ve worked in both clinical and community settings supporting people through anxiety, depression, trauma, life transitions, and moments where things just feel “off.” Whether you’re navigating stress, relationship challenges, burnout, or a deeper sense of feeling stuck, I’m here to help you make sense of it and move forward.
My approach is collaborative, down-to-earth, and tailored to you. I’m not the kind of therapist who just nods along—I’ll actively engage with you, offer insight, and help you connect patterns so you can create real, lasting change. I aim to create a space where you feel comfortable being fully yourself, while also gently challenging what’s no longer working.
I also specialize in Ketamine-Assisted Psychotherapy (KAP) through a partnership with Journey Clinical, working alongside medical providers who prescribe and monitor treatment. This can be a powerful option for those who feel stuck in traditional approaches or are looking for a deeper level of healing and perspective.
I work with adults from all walks of life who are ready to better understand themselves, improve their relationships, and feel more grounded and aligned in their day-to-day lives.
I always operate off of this model, "Everything I've gone through I have gotten through."
My work is grounded in behavioral therapy, and a firm belief that people can change. I prefer a flexible and collaborative approach that evolves as we work together. Though the foundation of my work is behavioral, I develop integrated treatment plans for each new client, drawing on other evidence-based modalities and new research.
Hi. I'm a therapist based in San Francisco. I provide therapy to people seeking support anxiety and depression-related issues, trauma, relationship and career challenges and those looking to change or examine their substance use patterns.

Are you are experiencing verbal and/or mental abuse from a romantic partner, a parent, sibling, friend, co-worker? Do you struggle with your own internal thoughts (e.g. "you’re not good enough”, "it's all your fault", “you are not a priority”). Maybe you’ve lost someone and you’re grieving. You are emotionally exhausted because of the pain you hide and the inability to say "no". You tell yourself the good is good but the bad is bad. You're scared and confused on what to do or how to "fix" things. These experiences create rumination, avoidance, trauma, anxiety, and more.
