Are you living with anxiety that won't quiet down, no matter how hard you try? Struggling with depression, or watching your teenager lose their footing? At Collaborative Therapy Clinic, we go deeper than symptom management. Our team of mature, experienced therapists brings not just clinical training, but real life experience to every session. You won't feel like a case file here. Using Internal Family Systems (IFS), we help you understand the parts of yourself that unconsciously drive your patterns — and create real, lasting change. We'd love to meet you. Start with a free 15-minute intro call.
We specialize in anxiety, depression, trauma, and relationship issues using Internal Family Systems (IFS), EMDR, and CBT. IFS is our core approach — helping you understand the parts of yourself driving your patterns, so you can heal rather than just cope. We offer individual, couples, teen, and family therapy, in-person and online.
We know reaching out takes courage. Whether you've never tried therapy before or have had experiences that left you uncertain, we meet you exactly where you are — without judgment. Our warm, experienced team is here when you're ready. You deserve more than just getting by. Take the first step — we've got you.

Therapy at our clinic begins with building a genuine sense of safety — because real change can't happen without it. Our therapists draw from a range of evidence-based approaches including CBT, DBT, EFT, ACT, and Attachment-based therapy, with some specializing in the deeper parts-work of IFS. Together we match the right approach to the right person — because no two clients are the same.

We don't believe one approach fits everyone. Our therapists are trained in multiple evidence-based modalities — CBT, DBT, EFT, ACT, IFS, EMDR, and Attachment-based therapy — and thoughtfully match the approach to each client's unique needs, history, and goals. The result is therapy that feels personal, not prescriptive.
