As a psychiatric prescriber, Guillermo specializes in medication management for ADHD, anxiety, and mood disorders such as depression and bipolar disorder, while also treating alcohol and drug use issues through evidence-based medication approaches. He works with children and adolescents experiencing behavioral or emotional concerns, as well as adults facing midlife and later-life transitions. Guillermo integrates Cognitive Behavioral Therapy–informed principles, mindfulness strategies, and collaborative decision-making into his care, and offers additional areas of focus to meet diverse mental health needs.
He also serves select populations including individuals on the autism spectrum, members of the LGBTQ+ community, and military veterans. Guillermo is particularly passionate about supporting individuals who have been recently discharged from a psychiatric hospital.
He understands that this transition can feel overwhelming and vulnerable, and he prioritizes continuity of care, medication stabilization, and relapse prevention during this critical period.
