Hi, I'm Mitch — a psychiatric mental health nurse practitioner with a Doctor of Nursing Practice from Vanderbilt University. San Diego has been home since 2020, when the Navy first brought me here.

My background includes pediatrics at Children’s Hospital in St. Paul, inpatient psychiatry in Nashville and San Diego, crisis stabilization, and outpatient mental health care. I’ve worked with veterans, college students, LGBTQ+ individuals, people experiencing homelessness, and patients navigating anxiety, depression, bipolar disorder, ADHD, trauma, substance use, and severe mental illness.
