Dr. Pascal Stirnimann is a board-certified Psychiatric Mental Health Nurse Practitioner in California who has been practicing since 2022. He has a BA in Psychology from University of Miami, a Master of Science in Nursing from Columbia University, and a Doctor of Nursing Practice from Columbia University. Dr. Stirnimann specializes in the treatment of young adults, adolescents, and children (4+), as well as other vulnerable populations including those in foster care and emancipated minors. He has experience in both inpatient and outpatient settings, including training at a women’s shelter.

Dr. Stirnimann takes a whole health, whole family, holistic view of treatment to determine the best personalized approach for an individual and their family. Using a shared decision-making model, he collaborates with clients to find the right blend of interventions to meaningfully improve the critical areas of life needed for a well-rounded and balanced way of living. Outside of work, Dr. Stirnimann loves discovering and immersing himself in the cultures of new hobbies. He has always found it fascinating that every hobby has its own language, slang, ideals, and gatekeepers. He also enjoys many forms of exercise including cycling, swimming, and hiking. He loves to cook, read, play video games, and is hoping to develop a green thumb.
