Dan Rothenberg – Supervisor and Clinical Lead
Therapist & Clinical Supervisor | Specializing in Teens, Young Adults, and Neurodiversity
Dan Rothenberg’s path to clinical practice has been defined by a unique blend of humor, resilience, and a deep-seated belief in human potential. His diverse background allows him to build immediate rapport and trust with clients who may otherwise feel misunderstood or judged by traditional therapeutic models.
A Foundation of Connection
As a standup comedian, Dan developed a knack for finding humor and levity within the intricacies of family life and personal struggle. This experience taught him that humor is more than entertainment—it is a powerful tool for connection and catharsis. Today, Dan integrates this warmth and levity into his clinical work, specifically with teens and young adults. By fostering a positive and nonjudgmental environment, he helps clients navigate difficult transitions with a sense of ease and authenticity.
From Advocacy to Strength-Based Practice
Prior to entering private practice, Dan served as a therapist for foster youth in Los Angeles. Working with under-served populations, he saw firsthand how negative labels—such as being a “bad kid”—can become internalized, stifling a young person’s extraordinary natural talents. This pivotal experience shaped his clinical philosophy: approaching every individual with curiosity rather than judgment. In his current practice in Southwest Portland, Dan remains a steadfastly strength-based practitioner. He operates under the belief that young people already possess the essential qualities for success; his role is to help them identify, unlock, and harness those strengths to align with their core values.
Clinical Supervision and Neurodiversity
Expanding his impact within the clinical community, Dan now provides clinical supervision to Registered Associates in Oregon. He offers specialized guidance for clinicians working with ADHD and Autism, ensuring that neurodivergent clients receive the affirming, strength-based care they deserve.
Whether working one-on-one with a young adult or mentoring the next generation of therapists, Dan is dedicated to stripping away limiting labels and empowering individuals to rewrite their own stories.
Chad Dahlstrom – Associate Counselor and Operations Lead
At OneYou Psychology, I lead with the belief that healthy systems and healthy people are inseparable. My background in product management and operations taught me that the most meaningful work happens in environments where team members feel supported, trusted, and invited to bring their full selves to the table. I focus on clarity, collaboration, and psychological safety, creating a culture where coaches and clinicians can do their best work without ego or hierarchy getting in the way. I value thoughtful decision-making, open communication, and mentoring others into leadership, and I work to ensure our team experiences the same steadiness, compassion, and encouragement we hope to offer our clients.
As a counselor with a master’s degree in Cognitive Behavioral Psychology, my work centers on understanding people deeply and helping them feel seen, supported, and capable of real change. My approach integrates CBT, IFS, mindfulness, and a trauma-informed lens to meet clients exactly where they are. I care about helping individuals make sense of their experiences, build confidence in their strengths, and move toward lives that feel more grounded and manageable. At OneYou Psychology, I’m committed to creating a space where clients feel safe, understood, and empowered and where our team feels aligned around the shared purpose of supporting the whole person, not just the problem they bring into the room.
