Mario Ruiz, PMHNP, helps adults and older adults across California stabilize symptoms, restore functioning, and move forward with confidence through thoughtful psychiatric care. He provides medication management for individuals navigating complex mental health concerns, offering a collaborative and respectful approach that prioritizes safety, clarity, and measurable improvement. Mario is known for taking time to understand each patient’s full picture, including medical history, life stressors, and treatment goals, so care feels personalized and effective.

Mario treats adults ages 18 and older, including seniors, and commonly supports conditions such as ADHD, mood disorders including depression and bipolar disorder, and PTSD. His work often includes addressing sleep-related concerns, anxiety symptoms, and challenges connected to major life transitions.

His approach emphasizes careful medication monitoring, clear communication, and coordination to help patients regain stability, reduce the risk of rehospitalization, and rebuild daily routines with confidence.

Mario serves diverse populations, including military members and veterans, first responders, and individuals with autism spectrum disorders, and offers care for additional populations as well.
