My Ideal Client

I work with neurodivergent adults who are exhausted from trying to function in ways that don't fit their brains. Many of my clients are Autistic, ADHD, or AUDHD adults navigating burnout, masking, trauma, anxiety, or difficult relationships. Whether you're newly diagnosed, self-identified, or have known for years, we'll work toward greater self-understanding and practical sustainable ways of living that honor who you are rather than who you've been told you should be.

My Approach to Helping

I believe that people make sense. Rather than asking, "What's wrong with you?" I want to understand what you've experienced, how your brain and nervous system learned to respond, and what you need now. My approach is humanistic, neurodivergent-affirming, trauma informed, and collaborative. You are the expert on your own life; therapy is something we do together, not something I do to you. I draw from EMDR, ACT, narrative therapy, neuroscience-informed psychoeducation, and other approaches based on what works for you. We might process experiences that still feel stuck in the past, untangle shame and expectations you've carried for years, or develop practical strategies that fit your actual life. My goal isn't to make you more "normal." It's to help you understand yourself, have more choices, and build a sustainable life that works with your brain rather than against it.

My Personal Beliefs and Interests

I'm openly Autistic, ADHD, bisexual, and a trauma survivor. Those experiences don't make me an expert on your life, but they do inform the kind of therapist I choose to me. I understand how exhausting it can be to navigate a world that wasn't designed with your brain, body, or identity in mind. I believe healing happens through genuine human connection, curiosity, and respect. Not perfection. My work is LGBTQIA+ affirming, sex-positive, disability-justice informed, and supportive of survivors of intimate partner violence. I welcome that complicated intersections of identity, relationships, trauma, disability, and neurodivergence. You are the authority on your own life; my job is to help you understand yourself more deeply and build something sustainable from there.

Techniques I Use

Specialties

  • Acceptance and Commitment Therapy (ACT) External link

    Acceptance and Commitment Therapy helps people stop fighting their thoughts and emotions and start building lives guided by their values. Rather than chasing perfection, ACT teacher psychological flexibility and self-compassion. I've received graduate training in ACT and use it as a foundation of my work with neurodivergent adults, integrating it with trauma-informed care and practical strategies tailored to each client's needs.

  • Humanistic  External link

    Humanistic Therapy is built on the belief that people grow through genuine human connections, self-understanding, and acceptance. Rather than viewing clients as problems to fix, it honors their inherent worth and capacity for change. My counseling philosophy is grounded in humanistic principles, emphasizing authenticity, empathy, collaboration, and the belief that clients are the experts on their own lives.

  • EMDR External link

    EMDR helps people process traumatic or distressing experiences that can leave the nervous system responding as though the past is still happening. Using bilateral stimulation, we gently work with memories, emotions, beliefs, and body sensations. The goal isn't to erase what happened, but to help your brain process it so the past feels like the past, and has less power over your present.

Issues I Treat

Specialties

  • Autism External link

    I offer neurodivergent-affirming therapy for Autistic adults, including those diagnosed later in life or who self-identify. I don't see autism as something to cure or overcome. We can explore masking, burnout, sensory needs, relationships, identity, self advocacy, and the experience of navigating a world that wasn't designed for you. Our goal is to understand your brain, reduce shame, and create sustainable ways of living that work for you.

  • ADHD External link

    I work with adults whose ADHD affects for more than attention. We can explore executive functioning, emotional regulation, overwhelm, shame, motivation, relationships, and the exhaustion of trying to meet expectations that don't fit your brain. Rather than simply telling you to "try harder," we'll work to understand your patterns, identify your needs, and develop practical, sustainable strategies that support the way your brain actually works.

  • Aspergers External link

    Asperger's is no longer a separate diagnosis, but many adults still identify with the term, or received this diagnosis in the past. I provide neurodivergent-affirming therapy focused on understanding your individual strengths, needs, relationships, sensory experiences, and ways of communicating. Rather than teaching you to appear more neurotypical, we'll explore what helps you live authentically and sustainably, with less masking and a greater self-understanding.

  • Domestic Abuse External link

    I work with survivors of intimate partner violence and understand that abuse can be emotional, physical, sexual, financial, coercive, or difficult to name at all. You won't be pressured to leave, stay, forgive, or make decisions before you are ready. Together, we can make sense of what you've experienced, rebuild your own perceptions, strengthen boundaries and safety, process trauma, and help you reclaim a life that belongs to you.

  • PTSD External link

    Trauma can leave your brain and nervous system responding as though the past is still happening. I work with adults experiencing PTSD and complex trauma using a compassionate, trauma-informed approach that can include EMDR. We can process distressing experiences while also working with shame, beliefs, emotions, body responses, triggers, and patterns developed to survive. The goal isn't to erase your past, but to help it have less power over your present.
