ERP Therapist for OCD and Anxiety in California

Licensed therapist Matthew Baker LCSW ERP Specialist smiling in a professional setting

Your OCD & Anxiety Specialist

I’m Matthew Baker, a California-licensed clinical social worker who works with adults, teens, and children struggling with OCD and anxiety-related conditions using Exposure and Response Prevention (ERP)—the most well-supported treatment for these conditions.


I work with people who feel stuck in cycles of worry, checking, avoidance, or mental loops that don’t seem to resolve—no matter how much effort they put into thinking their way out of them. Anxiety can quietly take over a lot of mental space and energy, even when life looks “fine” on the outside. My role is to help you change how you respond to fear and uncertainty so they have less control over your life.


ERP is the foundation of my work, but therapy isn’t one-size-fits-all. When helpful, I integrate evidence-based approaches such as Behavioral Activation (BA), Motivational Interviewing (MI), Habit Reversal Training (HRT) for body-focused repetitive behaviors (BFRBs), and Prolonged Exposure (PE) for co-occurring PTSD. These tools can support momentum and follow-through when hesitation, low motivation, or overlapping conditions make change more difficult.


I aim to create a space that is grounded, respectful, and non-judgmental. I’m genuinely curious about how your mind works and how your experiences fit together. While many people with anxiety share common patterns, your experience is unique and deserves to be understood on its own terms.

My approach is collaborative and structured. ERP is active, and progress happens through practice not just insight. I’ll help you move at a thoughtful, manageable pace while also encouraging you to gently stretch outside your comfort zone. Change is uncomfortable by nature, and you don’t have to do it alone.


I don’t just offer coping strategies to get through anxious moments. I guide you through a clear, step-by-step process designed to help you face fear rather than organize your life around it, so you can spend less time managing anxiety and more time living in line with what matters to you.

On a Personal Note

Outside of my work as a therapist, I’m a proud husband and father. I’ve always been an extrovert, though these days I’ve grown to appreciate a quieter, more home-centered life and time with my family. Over the years, my interests have ranged widely—video games, reading, yoga, cycling, soap making, cooking, coin collecting, gardening, publishing children’s books, and (unironically) baking.


People often tell me they feel comfortable talking with me quickly, which is one of the things I value most about this work. I’m naturally curious about people—how they think, what matters to them, and how they move through the world. I care deeply about connection, relationships, community, and simple living, and I try to bring that same sense of warmth, authenticity, and presence into the spaces I create with others.

Our Approach to Treatment for OCD and Anxiety

Whatif comes from the cycle of “what if…” questions at the heart of OCD and anxiety—questions that can feel urgent, insidious, and impossible to shut off. The name reflects the essence of ERP therapy: changing our relationship to uncertainty so “What if something goes wrong?” can gradually become “What if I don’t need to solve this thought?” or “What if I can handle not knowing?”


It’s also, in part, an homage to Shel Silverstein’s poem “Whatif,” which captures how worry can take over the mind. For my practice, the name marks a shift from fear-driven what ifs to a more open, curious, and hopeful way of moving through the world.

My work is grounded in Exposure and Response Prevention (ERP), the most well-supported treatment for OCD and anxiety-related disorders. ERP is an active, skills-based approach that focuses on changing how you respond to fear and uncertainty — not trying to eliminate thoughts or feelings.


While ERP serves as the foundation of treatment, I integrate additional evidence-based approaches only when clinically relevant, including:


  • Motivational Interviewing (MI) — to address ambivalence, hesitation, or difficulty engaging in exposure work 
  • Behavioral Activation (BA) — to reduce avoidance and rebuild momentum when depressive symptoms have narrowed daily life
  • Habit Reversal Training (HRT) — when body-focused or repetitive behaviors interfere with progress
  • Prolonged Exposure (PE) is used when trauma-related avoidance and fear conditioning contribute to PTSD symptoms that maintain anxiety and limit recovery.” 


These tools are used in service of ERP, not as separate or competing frameworks. Treatment is structured, goal-driven, and adapted to your specific presentation — without drifting into unfocused or exploratory therapy. Every intervention has a purpose, and progress is measured by real-world change.


The mission of Whatif Therapy is to help adults, teens and children across California break the cycle of fear, avoidance, and intrusive thoughts through effective, evidence-based treatment for OCD and anxiety-related conditions.


I work with adults, teens and children who reside in the state of California, who experience OCD, anxiety and fear based conditions (see full list of conditions).
