Andrea has been trained in AF-CBT to give families a different way to deal with conflict. Andrea has been trained in EMDR (Eye Movement desensitization and Reprocessing) which is a way to heal from past trauma so you can life in your preset life without being triggered by situations from the past.

Philosophy of Care

Holly Claire Werstein, Psychiatric Nurse Practitioner has 12+ years of experience in mental health.  Holly completed her BSN and MSN from the University of Texas at Austin. She became a psychiatric nurse practitioner in 2015. She also has a BA in Psychology, BCom in Management, and an MBA from the University of Otago in Dunedin, New Zealand.  She cares a great deal about people and wants to support her clients becoming their best selves. She knows that mental health is a foundational pillar to personal and community wellness. Without mental health, clients, relationships, careers, and families can falter. With it, they thrive!

From outpatient to inpatient care to emergency rooms and corrections, Holly has helped heal afflicted minds and emotions and assisted clients to find peace. With patient-centered medication prescribing, a trauma-informed approach, mindfulness, therapeutic laughter, and up-to-date neurobiological research, Holly supports both adolescent and adult clients.

Holly’s ideal clients are adolescents and adults seeking to be free and find peace from post traumatic stress disorder (PTSD), depression, anxiety, panic attacks, nightmares, disordered eating, psychotic and mood disorders, family conflict, existential crises, and/or life transitions. She is a member of the LGBTQ+ community and welcomes the opportunity to serve those questioning gender, orientation, and identity.
