Clinical Director | Licensed Professional Counselor (LPC)

Collin has been a part of Peaceful Practices’ clinical team since 2022. His clinical work blends several modalities, with intensive training in Internal Family Systems (IFS), Exposure and Response Prevention (ERP), Dialectical Behavior Therapy (DBT), and Rational Emotive Behavioral Therapy (REBT). For the last decade, Collin has been working extensively with ADHD, neurodivergent, LGBTQIA+, and identity-focused populations. Collin’s clinical style integrates these relational, psychodynamic, behavioral, and experiential therapies, particularly for individuals who have spent much of their lives feeling misunderstood, marginalized, “too much,” or somehow out of step with the world around them.

He believes meaningful therapy happens when people feel genuinely seen. His approach combines warmth, humor, curiosity, and deeply personal clinical training to create spaces where clients and clinicians alike can show up as full human beings. In clinical practice, he helps clients examine the dynamics behind their motivation and momentum, working with (not against) the miraculous complexity each person brings to their lives and the lives of those around them.

In addition to his extensive clinical work in attachment and identity, he supervises a multidisciplinary team of talented clinicians and is passionate about helping therapists grow into thoughtful, confident, and deeply attuned practitioners. He holds that creating a culture where authenticity, compassion, accountability, and the occasional well-timed meme, can coexist.

Collin previously worked with high-acuity patients facing chronic illnesses such as HIV/AIDS and opioid and stimulant addiction, and contributed to the University of Delaware attachment lab as well as research for the KiVa anti-bullying initiatives. His master’s thesis explored the experiences of chronically ill patients struggling with medication adherence. He has also worked across partial hospitalization, residential, and addiction treatment programs supporting individuals with bipolar disorder, schizophrenia, borderline personality disorder, and dissociative identity disorder. Over the past decade, Mr. Maier has helped hundreds of patients from diverse backgrounds, guided by Marcel Proust’s words: “The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.”

To Collin, that’s what therapy is about: not becoming someone else, but learning to see yourself, your life and influence on others with new eyes – compassionately and more fully, whatever your circumstances may be.
