Lindsey Miller, ARNP is a Board Certified Psychiatric Mental Health Nurse Practitioner, who provides diagnostic assessments and psychiatric medication management for children, adolescents, and young adults experiencing:

  • Autism

  • Depression

  • Anxiety

  • OCD

  • ADHD

  • Other related emotional and/or behavioral concerns

Lindsey also specializes in identifying autism across the lifespan, from young children to adults. Autism diagnostic evaluations are conducted through a team-based model with a clinical psychologist. Lindsey also supports autistic individuals and their families with resource navigation and treatment planning. She provides limited caregiver coaching and counseling support and, when needed, helps individuals and families connect with appropriate longer-term coaching or therapy services.

Lindsey also completes diagnostic evaluations for ADHD and other psychiatric conditions. However, please note that Lindsey does not administer neuropsychological tests. Evaluations will include patient and caregiver interviewing, coordination with collateral contacts, and completion of standardized questionnaires to assist in diagnostic clarification and treatment planning.

Lindsey strives to be evidence-based in her practice, and she understands that there is often the most benefit to medication when combined with therapy. She looks forward to being a resource to patients and families already established with a therapist at CAPSS, as well as with other community-based therapists. Lindsey will work collaboratively with a patient’s therapist to ensure clear understanding of treatment goals and progress.
