William Baerthlein, LICSW

I’m a clinical social worker with over 10 years of experience supporting individuals through some of life’s most challenging moments. I earned my undergraduate degree from Quinnipiac University and went on to complete my Master of Social Work at Boston University School of Social Work in 2015. Since then, I’ve had the privilege of working with a diverse range of clients navigating depression, anxiety, PTSD, and substance use.

I came into this field because I genuinely value the process of helping people better understand themselves and create meaningful change in their lives. I know that reaching out for therapy can feel overwhelming, and I don’t take for granted the trust it takes to share your story with someone new. My goal is to create a space where you feel comfortable, respected, and truly heard—without judgment.

My approach to therapy is pragmatic, individualized, and grounded in your unique strengths. I don’t believe in a one-size-fits-all model. Instead, I work collaboratively with each client to understand what’s most important to them and to develop tools and strategies that feel realistic and useful in everyday life. Whether we’re working through patterns of anxiety, processing past trauma, or addressing substance use, I aim to balance insight with practical steps forward.
