I’m Greg Desir, a Board-Certified Psychiatric-Mental Health Nurse Practitioner and founder of Brain Wave Psychiatry Services. My path into mental health care began at the bedside as a registered nurse, where I witnessed how deeply psychiatric symptoms affect every part of a person’s life. This experience inspired me to specialize in psychiatry so I could partner with patients in finding meaningful, lasting change. I provide comprehensive psychiatric evaluations and evidence-based medication management for adults ages 18 to 55 across California through secure telehealth. My areas of focus include anxiety, depression, ADHD, and mood disorders. While I do not provide psychotherapy directly, I work closely with patients to ensure they receive the right referrals for counseling and supportive services when needed. My goal is to create a space where you feel heard, understood, and supported. Together, we will develop a treatment plan that fits your unique needs and helps you move toward greater stability, clarity, and peace of mind
