I am an integrative clinician providing psychotherapy, coaching, and mindful medication management to support meaningful and lasting change. I am also a board-certified Psychiatric Mental Health Nurse Practitioner with a Master’s from UCSF (2018), where I trained at Langley Porter Psychiatric Hospital and Clinics. Additionally, I hold a Sociology degree from Dartmouth College, have completed coursework at the San Francisco Psychoanalytic Psychotherapy Training Program, and foundational studies in energy medicine at the Academy of Intuition Medicine. I continue to refine my work through ongoing psychoanalytic supervision.
As a Stanford-trained Psychiatrist, I offer medication management and therapy for a range of conditions including anxiety, depression, bipolar disorder, PTSD, anger, stress, burnout, divorce, addiction, and others. I see adults age 18-60. I am also board certified in Addiction Medicine. I am not treating ADHD with stimulant medications at the current time due to in-person visit requirements to prescribe controlled substances. I am unable to offer therapy only if you have another psychiatrist (I will need to manage your psychiatric medications).
Hello! I am a board-certified psychiatrist with extensive international clinical, research, and academic experience.
I completed my psychiatry residency at Texas Tech University Health Sciences Center, following a Clinical Neuroscience of Mood Disorders Fellowship at the Cleveland Clinic. Earlier in my career, I practiced as a psychiatrist in Istanbul, Turkey, after completing my medical degree at Ankara University School of Medicine.
My name is Luis Rosas, PMHNP-BC, and I’m a board-certified psychiatric nurse practitioner with a background in emergency nursing and mental health. I’ve spent years caring for patients in high-stress and crisis settings, which taught me the value of resilience, compassion, and meeting people where they are. I provide care for adults dealing with depression, anxiety, trauma, ADHD, bipolar disorder, and substance use challenges. My mission is to help clients regain balance, build strength, and move toward the life they want with clarity and confidence.
