Meet Bill

I bring a practical, compassionate, and straightforward approach to therapy. My style is collaborative and down-to-earth—I believe you should feel heard and supported while also being appropriately challenged to grow. I draw from Cognitive Behavioral Therapy (CBT), solution-focused strategies, Reality Therapy, mindfulness, and Stoic principles. Together, we focus on what is within your control, build practical skills, strengthen resilience, and help you move toward a life that feels more purposeful and authentic.
