About
Hi, I’m Dr. Tim Streitwieser. I help adults who feel worn down or stuck—whether from insomnia, chronic pain, health challenges, or the weight of depression, anxiety, trauma, or everyday stress. Many of the people I work with feel overwhelmed, exhausted, or not like themselves anymore. My role is to help you feel understood, supported, and capable of making meaningful, lasting change. I use evidence-based approaches, including CBT, to help improve sleep, manage pain, and build steadiness in both mind and body. From our first sessions, you can expect empathy, validation, and a clear, practical plan tailored to who you are and what matters most to you. With over 17 years of experience, I take a holistic approach that looks beyond symptoms to your whole life—your values, relationships, and goals. I’ve seen people genuinely get better and reconnect with what gives their lives meaning. Seeking help is a sign of strength! It is important to live well, and seeking help is a sign of strength! Specialties: When challenges arise, all areas of life are impacted. I use a comprehensive approach that works with psychological experiences (difficult thoughts & emotions), stuck behavioral patterns, social changes, cultural differences, and physical health problems. Your unique profile informs impactful treatment targets. Most of my clients see meaningful change within first month of therapy. Credentials & Experience: I have over 17 years of clinical experience, at the doctorate-level. Additionally, I have worked as Deputy Chief at major medical center and as a university professor. Extensive training has occurred with Health Psychology, including advanced insomnia, chronic pain, and adjustment challenges.
