Justin Nicolas, MSN, PMHNP-BC, Psychiatry in Lake Oswego, Oregon

Justin Nicolas helps teens, adults, and older adults throughout Oregon navigate mental health challenges with a thoughtful, evidence-based approach that combines medication management and therapeutic support. As a psychiatric nurse practitioner at LifeStance Health, he works collaboratively with patients to better understand their symptoms, build resilience, and create treatment plans tailored to their goals. His clinical interests include treating anxiety, depression, and ADHD, while also supporting individuals facing a wide range of other mental health concerns. Justin is particularly passionate about working with first responders and supporting women’s health needs. He recognizes the unique pressures that can come with demanding careers, life transitions, caregiving responsibilities, and hormonal or reproductive health changes. His approach emphasizes creating a safe, respectful environment where patients feel heard and empowered to take an active role in their mental health journey. By combining compassionate care with clinical expertise, he helps patients develop practical strategies for lasting emotional well-being. Drawing from interventions such as Cognitive Behavioral Therapy (CBT) and mindfulness-based techniques, Justin incorporates therapeutic tools alongside medication management when appropriate. He believes effective psychiatric care should address the whole person, considering biological, psychological, and lifestyle factors that influence mental health. In addition to his primary areas of focus, he works with individuals experiencing a variety of other concerns, including mood disorders, trauma-related conditions, sleep difficulties, grief, and life transitions. He also values staying informed about advances in psychiatry and neuroscience so he can provide high-quality, patient-centered care. Outside of work, Justin enjoys spending time with his family, exploring the outdoors, traveling, and photography. He also has a strong interest in lifelong learning, personal growth, psychiatry, and neuroscience, interests that reflect the curiosity and compassion he brings to his work with patients every day.
